Liposuction Glossary

American Association for Accreditation of Ambulatory Surgery Facilities. The most common accrediting body for office-based surgical suites where liposuction is performed. AAAASF accreditation requires facilities to meet stringent standards for equipment, safety, personnel, and emergency preparedness.

Accreditation Association for Ambulatory Health Care. An accrediting organisation for ambulatory healthcare facilities, including surgery centers. AAAHC accredits over 5,000 organisations in the United States. AAAHC accreditation indicates a facility meets high standards for patient safety and quality care.

The area of the body between the chest and pelvis, commonly referred to as the belly or stomach area. The most frequently treated area in liposuction, including upper abdomen, lower abdomen, and the area around the navel (umbilicus). Abdominal liposuction accounts for the largest share of all liposuction procedures performed.

/ab-DOM-in-oh-plas-tee/

Commonly known as a "tummy tuck." A surgical procedure that removes excess skin and fat from the abdomen and tightens the underlying abdominal muscles. Often combined with liposuction for comprehensive abdominal contouring. Abdominoplasty addresses loose skin, which liposuction alone cannot.

American Board of Medical Specialties. The umbrella organisation that oversees 24 recognized medical specialty boards in the United States, including the American Board of Plastic Surgery (ABPS). ABMS recognition is the gold standard for verifying board certification.

American Board of Plastic Surgery. The only ABMS-recognized certifying board for plastic surgeons in the United States. ABPS certification requires graduation from an accredited medical school, at least five years of surgical residency training, and passing comprehensive written and oral examinations. This is the certification to look for when choosing a liposuction surgeon.

/AD-ih-poh-site/

A fat cell. Each adipocyte stores fat (triglycerides) and can expand or shrink depending on energy balance. Liposuction permanently removes adipocytes from the treated area. Remaining adipocytes can still enlarge with weight gain.

/AD-ih-pohs/

The medical term for body fat. Adipose tissue is composed of fat cells (adipocytes) that store energy in the form of triglycerides. Liposuction targets subcutaneous adipose tissue — the fat layer between the skin and the muscle. Visceral adipose tissue surrounds internal organs and cannot be treated with liposuction.

A small incision (typically 3–5 mm) through which the liposuction cannula is inserted. Adits are strategically placed in natural skin creases or areas concealed by clothing. Most heal to nearly invisible scars.

Surgical procedures performed to improve appearance rather than to treat a medical condition. Liposuction is classified as an aesthetic (cosmetic) surgery procedure when performed for body contouring purposes.

A healthcare facility where surgical procedures that do not require overnight hospitalisation are performed. Most liposuction procedures take place in ambulatory surgery centers or office-based surgical suites. Accredited ASCs are required to meet standards for safety, staffing, and equipment.

A physician (MD or DO) who specialises in administering anesthesia and monitoring patients during surgery. Board-certified anaesthesiologists complete four years of specialized residency training after medical school.

/an-es-THEE-zhuh/

The use of medications to prevent pain during surgery. The three main types used for liposuction are local anesthesia (numbing the treatment area only), IV sedation / Monitored Anesthesia Care (systemic relaxation combined with local numbing), and general anesthesia (complete unconsciousness). The type chosen depends on procedure extent and patient factors.

American Society for Aesthetic Plastic Surgery. A professional organisation exclusively devoted to cosmetic surgery, with approximately 2,600 members. Membership requires ABPS certification, at least three years of practice, sufficient cosmetic case volume, and peer sponsorship. ASAPS membership indicates a focus on aesthetic surgery.

/AS-pir-ayt/

The material removed during liposuction — a mixture of fat, tumescent fluid, and a small amount of blood. The aspirate is collected in a transparent canister during the procedure, allowing the surgeon to monitor volume and composition. Total aspirate volume is a key safety metric; volumes exceeding 5 liters are classified as "large volume" liposuction.

American Society of Plastic Surgeons. The world's largest organisation of board-certified plastic surgeons, representing over 90% of ABPS-certified surgeons in the United States. ASPS membership requires board certification, continuing education, and adherence to a code of ethics.

Unequal appearance between the two sides of the body. Some asymmetry is natural and present before surgery. Post-operative asymmetry may occur due to uneven swelling (temporary) or unequal fat removal (may require revision). Minor asymmetry is common during the healing phase and often resolves as swelling subsides over 3–6 months.

A procedure that combines liposuction (to harvest fat from areas like the abdomen or thighs) with fat transfer (injecting the harvested fat into the buttocks for augmentation). BBL carries significantly higher risk than liposuction alone, primarily due to the risk of fat embolism during fat injection.

A measurement calculated from height and weight (weight in kg ÷ height in m²) used as a general indicator of body fat. Ideal liposuction candidates typically have a BMI under 30. Published studies show that complications like VTE and death are associated with higher median BMIs (approximately 30 kg/m²). BMI does not distinguish between fat and muscle.

A credential indicating that a physician has completed specialized training and passed rigorous examinations in a specific medical specialty. For plastic surgery, the relevant board certification is from the ABPS, which is recognized by the ABMS. Be cautious of certifications from non-ABMS-recognized boards.

A category of procedures designed to reshape and sculpt the body's silhouette. Liposuction is the most common body contouring procedure. Other body contouring procedures include abdominoplasty, arm lift (brachioplasty), thigh lift, and body lift.

/dis-MOR-fik/

A mental health condition characterized by obsessive focus on perceived flaws in appearance that are not observable or appear minor to others. Patients with BDD may seek cosmetic procedures but are unlikely to be satisfied with results. Ethical surgeons screen for BDD and may recommend psychological evaluation before surgery.

A surgical procedure that removes excess skin and fat from multiple areas, typically including the abdomen, buttocks, hips, and thighs. Often performed after massive weight loss. More extensive than liposuction alone, addressing loose skin that liposuction cannot correct.

The area of fat that bulges around the bra line on the back, typically between the armpit and waist. A common treatment area for liposuction, particularly in women. May also include fat extending towards the flanks.

/BRAY-kee-oh-plas-tee/

An arm lift procedure that removes excess skin and fat from the upper arms. Sometimes combined with liposuction of the arms for more comprehensive contouring.

Discoloration of the skin caused by blood leaking from damaged blood vessels into surrounding tissue. Bruising is universal after liposuction and typically resolves within 2–4 weeks. Severity varies by technique, treatment area, and individual healing factors.

/KAN-yoo-luh/

A thin, hollow metal tube used to suction fat during liposuction. Cannulas come in various sizes (typically 2–4 mm diameter for modern liposuction) and designs. The cannula is inserted through small incisions and moved through the subcutaneous fat layer in a back-and-forth motion to break up and remove fat.

A validated clinical tool used to assess a patient's risk of venous thromboembolism (blood clots) before surgery. The Caprini Score considers factors such as age, BMI, history of blood clots, type of surgery, and other risk factors. A responsible liposuction surgeon uses this or a similar tool for preoperative risk stratification.

A healthcare-specific credit card commonly used to finance cosmetic procedures, including liposuction. CareCredit offers promotional 0% interest periods, but charges deferred interest (typically 27–29% APR) on balances not paid in full by the end of the promotional period.

The dimpled, uneven appearance of skin caused by fat pushing through the connective tissue beneath the skin. Liposuction is not a treatment for cellulite and may in some cases make cellulite more visible by reducing the fat layer beneath the skin surface.

A tight-fitting elastic garment worn over treated areas after liposuction. Compression garments reduce swelling, support the skin during contraction, minimise fluid accumulation, and improve comfort. Typically worn 24/7 for 2–4 weeks, then during the day for an additional 2–4 weeks. Proper fit and consistent wear are important for optimal results.

Unevenness, asymmetry, lumps, or depressions in the treated area after liposuction. The most common complication, occurring in approximately 2.35% of patients according to meta-analysis data. May be caused by uneven fat removal, healing variability, or poor skin retraction. Minor irregularities often improve as swelling resolves; persistent ones may require revision.

An insurance program that covers the cost of treating complications from cosmetic surgery. CosmetAssure's claims database has been used in major published studies analysing complication rates for cosmetic procedures, including liposuction.

Certified Registered Nurse Anaesthetist. An advanced practice registered nurse trained to administer anesthesia. CRNAs provide anesthesia for many liposuction procedures, either independently or under the supervision of an anaesthesiologist.

/throm-BOH-sis/

A blood clot that forms in a deep vein, usually in the leg. DVT is a serious potential complication of any surgery. If the clot breaks free and travels to the lungs, it becomes a pulmonary embolism (PE), which can be life-threatening. DVT risk increases with obesity, immobility, general anesthesia, combined procedures, and certain genetic conditions.

/DER-mis/

The layer of skin beneath the epidermis (outer skin), containing blood vessels, nerves, hair follicles, and connective tissue. The dermis provides skin with its elasticity and strength. Damage to the dermis during liposuction can cause scarring or contour irregularities.

A small tube sometimes placed in the surgical site to allow fluid to exit the body. Drains are not routinely used in liposuction — many surgeons instead leave incision sites partially open to allow natural drainage of residual tumescent fluid. When used, drains are typically removed within a few days to two weeks.

The original liposuction technique (largely abandoned) in which fat was removed without injecting any fluid into the treatment area beforehand. The dry technique was associated with significant blood loss and has been replaced by tumescent, wet, and superwet techniques.

Preventive measures taken to reduce the risk of deep vein thrombosis. For liposuction, these include sequential compression devices on the legs during surgery, early ambulation after the procedure, chemical prophylaxis (blood-thinning medication) for higher-risk patients, and adequate hydration.

/ek-ih-MOH-sis/

The medical term for bruising; discoloration of the skin resulting from bleeding underneath. Common after liposuction and varies in extent based on technique, treated area, and individual factors. Progresses through purple, blue, green, and yellow phases before resolving.

/ih-DEE-muh/

Swelling caused by excess fluid accumulation in body tissues. Post-operative edema is universal after liposuction and is the primary reason final results are not visible immediately. Swelling peaks at 2–5 days, improves substantially by 4–6 weeks, and fully resolves by 3–6 months in most patients. Compression garments, elevation, lymphatic massage, and movement help reduce edema.

/EM-boh-lizm/

A blockage of a blood vessel caused by a substance traveling through the bloodstream. In the context of liposuction, the two relevant types are pulmonary embolism (a blood clot blocking a lung artery) and fat embolism (fat particles blocking blood vessels). Both are rare but potentially life-threatening.

/ee-mul-sih-fih-KAY-shun/

The process of breaking down fat into smaller particles, making it easier to remove. VASER liposuction uses ultrasound energy to emulsify fat before suctioning; laser liposuction uses thermal energy. Emulsification may allow gentler fat removal and potentially better skin retraction.

/ep-ih-DER-mis/

The outermost layer of skin, providing a waterproof barrier and creating skin tone. Liposuction is performed beneath the epidermis in the subcutaneous fat layer. The small incisions through the epidermis typically heal with minimal scarring.

/ep-ih-NEF-rin/

A hormone and medication that constricts blood vessels. Epinephrine is a key component of the tumescent solution used in liposuction — it dramatically reduces bleeding during the procedure by constricting blood vessels in the treatment area. The inclusion of epinephrine in tumescent solution was a major safety advance in liposuction history.

The surgical removal of tissue by cutting. In the context of body contouring, excision refers to removing excess skin (as in abdominoplasty), as distinct from liposuction, which removes fat by suction.

/FASH-ee-uh/

A thin sheath of fibrous connective tissue that surrounds muscles and organs. In liposuction, the superficial fascia separates superficial fat (which can be suctioned) from deeper tissues. The deep fascia should not be penetrated during standard liposuction procedures.

/AD-ih-poh-sites/

Specialised cells that store energy as fat. Adults have a relatively fixed number of fat cells; liposuction permanently removes fat cells from treated areas. Remaining fat cells can still enlarge with weight gain, which is why maintaining stable weight after liposuction is important.

/EM-boh-lizm/

A rare but serious condition in which fat particles enter the bloodstream during surgery and travel to the lungs, brain, or other organs, causing blockages. Fat embolism is more likely with large-volume liposuction, aggressive technique, and combined procedures (especially BBL). It was the most common cause of death in CDC investigations of cosmetic surgery fatalities. Symptoms include breathing difficulty, confusion, and rash. Requires immediate medical attention.

A procedure in which fat removed by liposuction is purified and then injected into another area of the body for augmentation. Common applications include the buttocks (BBL), breasts (fat transfer breast augmentation), face, and hands. Not all harvested fat survives transfer.

/fy-BROH-sis/

The formation of excess scar tissue in the treated area after liposuction. Fibrosis can cause firmness, lumps, or a hard feeling under the skin. It typically develops 2–8 weeks after surgery and often improves with lymphatic massage, time, and in some cases ultrasound therapy. Severe fibrosis may require additional procedures.

The sides of the torso between the ribs and hips, commonly called "love handles." One of the most popular treatment areas for liposuction in both men and women. Flank liposuction can create a more defined waistline and is a key component of Lipo 360.

The medical management of fluid balance during and after liposuction. Large volumes of tumescent fluid are injected during the procedure, and maintaining proper fluid balance is critical to preventing complications such as pulmonary edema and hypovolaemia.

A state of controlled unconsciousness induced by inhaled and/or intravenous anesthetic medications. Under general anesthesia, the patient has no awareness of the procedure. A breathing tube or laryngeal mask airway is placed to maintain the airway. General anesthesia carries specific risks (DVT, airway complications, nausea) that are not present with local anesthesia.

/gy-neh-koh-MAS-tee-uh/

Enlarged breast tissue in males. Liposuction is a common treatment for gynecomastia, often combined with direct excision of glandular tissue. Liposuction for gynecomastia may be covered by insurance if specific diagnostic criteria are met.

/hee-muh-TOH-muh/

A collection of blood outside of blood vessels, forming a firm, sometimes painful lump under the skin. Hematomas occur in approximately 0.27% of liposuction patients. Small hematomas typically resolve on their own; larger ones may need to be surgically drained. Risk is minimized by avoiding blood thinners before surgery.

An advanced technique that sculpts fat to enhance the visibility of underlying muscles, creating an athletic, toned appearance. Often uses VASER to precisely remove fat around muscle groups. Popular for creating visible abdominal etching, defined chest, and athletic contours. Requires a highly skilled surgeon and a lean patient with good skin elasticity.

/hy-per-pig-men-TAY-shun/

Darkening of the skin in treated areas, caused by haemosiderin (iron from degraded blood cells) depositing in the skin during bruise resolution. Occurs in approximately 1.49% of patients. More common in patients with darker skin tones. Usually fades over 3–12 months. Sun protection of treated areas during healing is essential.

/hy-poh-der-MOK-lih-sis/

The injection of fluid into subcutaneous tissue. The tumescent technique is essentially a specialized form of hypodermoclysis — delivering large volumes of dilute anesthetic solution directly into the fat layer.

/in-SIH-zhun/

A surgical cut made in the skin. Liposuction incisions (adits) are typically 3–5 mm in length and heal to nearly invisible scars. They are placed in natural skin creases or areas concealed by clothing.

/in-doo-RAY-shun/

Hardening or firmness of tissue that can occur after liposuction due to swelling, fibrosis, or healing. Common in the first few weeks to months after surgery. Usually resolves over time with massage and patience. Persistent induration may indicate fibrosis.

The process of injecting tumescent fluid into the treatment area before liposuction. The fluid contains saline, lidocaine (anesthetic), and epinephrine (to constrict blood vessels). Proper infiltration numbs the area, reduces bleeding, and makes fat easier to remove.

The process by which a patient gives permission for a medical procedure after receiving comprehensive information about its risks, benefits, alternatives, and expected outcomes. Informed consent for liposuction should cover specific risks, realistic expectations, alternative treatments, recovery timeline, and costs.

International Society of Aesthetic Plastic Surgery. A global organisation that verifies plastic surgery specialisation for its members. ISAPS membership is a useful credential marker when evaluating surgeons abroad.

Joint Commission International. The international arm of the Joint Commission, which accredits healthcare organisations worldwide. JCI accreditation is the gold standard for evaluating surgical facility safety outside the United States.

An independent, not-for-profit organisation that accredits and certifies healthcare organisations in the United States. Joint Commission accreditation represents the highest standard of healthcare facility evaluation. Sometimes referred to by its former name, JCAHO.

/KEE-loyd/

A type of raised, thickened scar that grows beyond the boundaries of the original wound. Keloid formation is a genetic predisposition more common in patients with darker skin tones. Patients with a history of keloid scarring should discuss this with their surgeon before liposuction.

Liposuction in which the total aspirate (fat plus tumescent fluid) exceeds 5 liters. The ASPS considers large-volume liposuction to carry higher risk and recommends additional safety precautions, including overnight monitoring in a medical facility.

A liposuction technique that uses laser energy delivered through a thin fiber optic probe to melt fat before suctioning. Marketed for skin tightening via collagen stimulation, though evidence for clinically meaningful skin contraction is debated. Carries a specific risk of thermal burn injury.

/LY-doh-kayn/

A local anesthetic medication that blocks nerve signals to prevent pain. Lidocaine is the primary anesthetic agent in the tumescent solution used for liposuction. The established safe upper limit for tumescent liposuction is 35–55 mg/kg. Peak blood levels occur 12–14 hours after injection due to the slow absorption from subcutaneous fat.

A serious condition that occurs when blood levels of lidocaine rise above the safe threshold. Early symptoms include ringing in the ears (tinnitus) and numbness around the mouth. Progressive toxicity can cause muscle twitching, seizures, and cardiac complications. Rare (0.016% of patients) but requires awareness during the first 24 hours after a tumescent liposuction procedure.

/lip-eh-DEE-muh/

A chronic medical condition characterized by abnormal, symmetrical fat accumulation — typically in the legs and sometimes the arms — that does not respond to diet or exercise. Lipedema is distinct from obesity and lymphedema. Liposuction for lipedema is a therapeutic (not cosmetic) procedure and may be covered by some health insurance plans.

A colloquial term for circumferential liposuction of the midsection — treating the abdomen, flanks, and lower back in a single procedure to contour the waist from all angles. Lipo 360 involves larger treatment areas, longer operative time, and greater total aspirate volume than single-area liposuction.

/lip-oh-ab-DOM-in-oh-plas-tee/

A combination procedure that includes both liposuction and tummy tuck (abdominoplasty) performed together. Allows comprehensive body contouring by removing excess fat and loose skin while tightening abdominal muscles. More extensive than either procedure alone.

/LIP-oh-fill-ing/

Another term for fat transfer or fat grafting. The process of injecting processed fat (harvested through liposuction) into areas requiring volume enhancement. Common applications include buttock augmentation (BBL), breast enhancement, and facial rejuvenation.

/ly-POL-ih-sis/

The breakdown of fat. In the context of body contouring, may refer to surgical fat removal (liposuction) or non-surgical fat reduction treatments that destroy fat cells through cold (CoolSculpting), heat, or injection (Kybella).

/LIP-oh-suk-shun/

A surgical procedure that removes localised deposits of subcutaneous fat through small incisions using a hollow tube (cannula) connected to a vacuum. The most commonly performed cosmetic surgical procedure in the United States, with over 490,000 procedures annually.

Anesthesia achieved by injecting numbing medication directly into the treatment area, without rendering the patient unconscious. In liposuction, local anesthesia is delivered via the tumescent technique. Patients remain fully awake and can communicate with the surgical team. Safer than general anesthesia for smaller procedures.

A specialized manual massage technique that promotes the movement of lymphatic fluid through the body. Frequently recommended after liposuction to reduce swelling, prevent fibrosis, and promote smoother healing. Typically performed by a trained lymphatic massage therapist starting 1–2 weeks after surgery.

A type of anesthesia in which sedative and analgesic medications are administered intravenously while the treatment area is also numbed with local anesthesia. Often called "twilight sedation" or "IV sedation." The patient is relaxed and drowsy but not fully unconscious. An anaesthesiologist or CRNA monitors the patient throughout. MAC is commonly used for liposuction when the patient prefers not to be fully awake but the procedure doesn't require general anesthesia.

/MAY-lar/

The fat pad in the cheek area of the face. May be treated with buccal fat removal or facial liposuction for facial slimming. Careful assessment is needed as excessive removal can cause premature facial aging.

Professional liability insurance that protects physicians against claims of medical negligence. A surgeon who carries adequate malpractice insurance provides a layer of financial protection for the patient in the event of a complication caused by error. Some surgeons operate without malpractice coverage ("going bare"), which is a red flag.

/BYU-pih-vay-kayn/

A long-acting local anesthetic sometimes used in conjunction with or as an alternative to lidocaine. Occasionally added to the tumescent solution or injected at incision sites to extend post-operative numbness.

An informal term for liposuction involving very large volumes of fat removal, typically exceeding 5 liters of total aspirate. Mega-liposuction carries significantly higher risks and is not routinely recommended by most board-certified plastic surgeons.

A non-surgical technique involving injections of medications, vitamins, or other substances into the fat layer to dissolve localized fat. Mesotherapy is not liposuction and is not endorsed by most plastic surgery professional organisations due to limited evidence for efficacy and safety concerns.

A very small cannula, typically under 3 mm in diameter. Microcannulas allow for finer, more precise fat removal and smaller incisions. Often used for delicate areas such as the chin, neck, and inner thighs.

/neh-KROH-sis/

The death of body tissue, usually due to insufficient blood supply. Skin necrosis is a rare complication of liposuction (approximately 0.046% of patients per meta-analysis data), more likely with aggressive superficial liposuction, thermal injury from laser or ultrasound devices, or in patients who smoke.

Injury to sensory or motor nerves in the treated area. Temporary numbness, tingling, or altered sensation is very common after liposuction and typically resolves within weeks to months as nerves regenerate. Permanent nerve damage is rare with modern techniques and appropriately sized cannulas.

A category of non-surgical treatments that reduce localized fat without incisions or anesthesia. Examples include CoolSculpting (cryolipolysis), SculpSure (laser), and Kybella (injectable). These treatments produce more modest results than liposuction and require multiple sessions, but involve no surgical risk or downtime.

Non-Steroidal Anti-Inflammatory Drug. Common NSAIDs include ibuprofen (Advil, Motrin) and naproxen (Aleve). NSAIDs must be discontinued before liposuction because they inhibit platelet function and increase bleeding risk. Paracetamol (acetaminophen/Tylenol) is not an NSAID and is generally safe to take before and after liposuction.

Temporary or permanent loss of sensation in treated areas. Common after liposuction due to nerve irritation or disruption during fat removal. Usually temporary, resolving over weeks to months as nerves regenerate. Permanent numbness is rare but possible, especially in areas with extensive treatment.

Surgical procedures performed in a physician's office-based surgical suite rather than in a hospital or ambulatory surgery center. Many liposuction procedures are performed in office-based settings. When the facility is accredited (AAAASF, AAAHC, or Joint Commission), outcomes are comparable to hospital-based procedures.

A rare but serious complication (approximately 0.04%) in which the liposuction cannula penetrates through the muscle wall into the abdominal cavity, potentially puncturing an internal organ. Risk is highest during abdominal liposuction, particularly in patients who have had previous abdominal surgery (which can thin the muscle wall). Prevention depends on proper technique and experienced hands.

A liposuction technique in which the cannula vibrates mechanically (typically using a reciprocating or oscillating motion), allowing the surgeon to remove fat more efficiently with less physical effort. PAL is particularly useful in fibrous areas (male chest, back, scar tissue from previous liposuction) and for large-volume cases.

/par-es-THEE-zhuh/

Abnormal sensations such as tingling, pins-and-needles, burning, or crawling feelings on the skin. Temporary paresthesia in the treated area is common after liposuction as nerves recover and typically resolves within weeks to months.

The flow of blood through tissue. Adequate perfusion is essential for wound healing after surgery. Smoking impairs perfusion by constricting blood vessels, which is why smoking cessation is required before liposuction.

/per-ee-OP-er-uh-tiv/

The period encompassing the time before (preoperative), during (intraoperative), and after (postoperative) surgery.

A component of blood that contains concentrated platelets and growth factors. Some surgeons inject PRP into liposuction treatment areas to potentially improve healing and skin quality. Evidence for PRP's effectiveness in this context is limited.

The small incision through which the cannula is inserted; also called an access site, entry point, or adit. Strategic placement minimises visible scarring. Common locations include natural skin creases, the navel, and areas hidden by clothing.

The period after surgery. Post-operative care after liposuction includes compression garment wear, activity restrictions, wound care, pain management, and scheduled follow-up appointments. The post-operative period is crucial for achieving optimal results.

The period before surgery. Pre-operative preparation for liposuction includes medical evaluation, medication adjustments, laboratory testing (if required), smoking cessation, and practical arrangements for recovery.

/TOH-sis/

Sagging or drooping of tissue. In the context of liposuction, ptosis refers to skin sagging that may result from removing fat without addressing excess skin. Patients with significant ptosis may need skin excision procedures (abdominoplasty, arm lift, etc.) in addition to or instead of liposuction.

/PUL-moh-ner-ee EM-boh-lizm/

A blockage of one or more arteries in the lungs, usually caused by a blood clot that has travelled from the legs (DVT). PE is the most serious thrombotic complication of liposuction and a leading cause of liposuction-related deaths. Symptoms include sudden shortness of breath, chest pain, coughing up blood, and rapid heart rate. PE requires immediate emergency medical treatment.

A small clip-on device (usually placed on the fingertip) that continuously monitors blood oxygen levels and heart rate. Pulse oximetry is a standard monitoring tool used during all liposuction procedures regardless of anesthesia type.

Systematic processes used by healthcare facilities to monitor outcomes, identify problems, and improve care. Accredited surgical facilities are required to maintain QI programs, including tracking complication rates and implementing corrective actions when needed.

The healing period following surgery. Liposuction recovery is progressive: initial discomfort and swelling improve over 1–2 weeks, most normal activities resume within 2–4 weeks, and final results are visible at 3–6 months.

A secondary surgical procedure performed to correct or improve the results of a previous surgery. In the context of liposuction, revision may be needed to address contour irregularities, asymmetry, or areas of over- or under-correction. Approximately 6–9% of liposuction patients undergo revision. Revision should not be performed until at least 6 months after the original procedure.

A balanced crystalloid solution sometimes used as the base fluid in tumescent solutions instead of normal saline. Ringer's lactate more closely mimics the body's natural electrolyte composition.

A sterile solution of 0.9% sodium chloride in water. Normal saline is the base fluid in most tumescent solutions used for liposuction. It serves as a carrier for lidocaine and epinephrine and provides the volume that swells the fat layer.

A mark left on the skin after a wound heals, formed by the body's production of collagen during tissue repair. Liposuction incisions are small (3–5 mm) and typically heal to minimal, nearly invisible scars. Scar appearance is influenced by genetics, skin color, wound tension, and post-operative care.

Medication that induces a state of relaxation and reduced awareness, used in combination with local anesthesia for patient comfort. IV sedation ("twilight") keeps patients drowsy but arousable. Different from general anesthesia in that the patient breathes independently. See also: MAC (Monitored Anesthesia Care).

Inflatable cuffs placed on the lower legs during surgery that intermittently inflate and deflate, mimicking the action of walking to promote blood flow and reduce the risk of DVT. SCDs are a standard safety measure during liposuction and most surgical procedures.

/suh-ROH-muh/

A collection of serous fluid (clear, yellowish body fluid) that accumulates beneath the skin after surgery. Seromas occur in approximately 0.65% of liposuction patients. Small seromas may resolve on their own; larger ones may need to be aspirated (drained with a needle) by your surgeon. Consistent compression garment wear helps prevent seromas.

The ability of skin to stretch and then return to its original shape. Good skin elasticity is important for achieving smooth, tight results after liposuction — the skin must contract to conform to the reduced fat layer. Elasticity is determined by age, genetics, sun exposure, smoking history, and previous skin stretching (from pregnancy or major weight changes).

Surgical removal of excess skin, performed in procedures like tummy tucks, arm lifts, and thigh lifts. May be necessary when liposuction alone cannot address loose or excess skin. Results in longer scars but addresses issues that liposuction cannot.

The process by which skin tightens and contracts after liposuction to conform to the new body contour. Good skin retraction is essential for a smooth result. Techniques such as VASER and radiofrequency-assisted liposuction may enhance skin retraction.

A brand name for laser-assisted liposuction. See: Laser-Assisted Liposuction. Claims to liquefy fat and stimulate collagen production for skin tightening. The laser fiber is inserted through a small cannula. Results vary; traditional liposuction remains the gold standard.

/sub-kyoo-TAY-nee-us/

Beneath the skin. Liposuction targets the subcutaneous fat layer — the fat that lies between the skin and the underlying muscle fascia. This is distinct from visceral fat (fat around internal organs), which cannot be removed by liposuction.

/sub-MEN-tal/

Liposuction of the area under the chin and along the jawline, performed to reduce a "double chin" and define the jaw and neckline. Submental liposuction is typically a shorter, less invasive procedure often performed under local anesthesia.

Liposuction performed in the fat layer just beneath the skin (as opposed to the deeper fat layer). Superficial liposuction can enhance skin retraction and definition but carries higher risks of skin irregularity and necrosis if performed too aggressively.

A variation of the tumescent technique in which the volume of fluid injected equals the expected volume of fat to be removed (a 1:1 ratio). This is less fluid than the full tumescent technique but more than the "wet" technique. Some surgeons prefer superwet technique for larger procedures performed under general anesthesia.

A stitch used to close a wound. Liposuction adits may be closed with a single suture, surgical adhesive strips, or left open to drain. When sutures are placed, they may be absorbable (dissolving on their own) or non-absorbable (requiring removal at a follow-up appointment, typically at 5–7 days).

Accumulation of fluid in tissues after liposuction; a normal part of healing. See also: Edema. Peak swelling typically occurs 2–5 days post-surgery. Most swelling resolves within 4–6 weeks, but residual swelling can persist for 3–6 months. Compression garments and lymphatic massage help reduce swelling.

Damage to tissue caused by heat. A specific risk of laser-assisted and ultrasound-assisted liposuction techniques, in which energy devices generate heat in the treatment area. Thermal burns occur in approximately 0.25% of liposuction patients (meta-analysis data) and are more common with laser-assisted techniques.

/throm-boh-FIL-ee-uh/

An inherited or acquired condition that increases the tendency to form blood clots. Patients with known thrombophilia are at higher risk for DVT/PE during and after surgery and require haematology consultation, aggressive prophylaxis, and careful risk-benefit analysis before elective liposuction.

/too-MES-ent/

The modern standard technique for liposuction, developed by dermatologist Dr. Jeffrey Klein in the 1980s. Large volumes of a dilute solution of lidocaine and epinephrine in saline are injected into the fat layer before suctioning. The tumescent technique revolutionised liposuction safety by dramatically reducing blood loss, providing effective local anesthesia, and enabling outpatient procedures.

The pattern of cannula movement during liposuction. The surgeon creates multiple overlapping tunnels through the fat layer by passing the cannula in a criss-cross pattern. This systematic approach ensures even fat removal and smooth results.

A liposuction technique that uses ultrasound energy to liquefy fat cells before they are suctioned out. VASER is the most widely used ultrasound-assisted system. Ultrasound energy selectively targets fat cells while preserving blood vessels, nerves, and connective tissue, allowing for more precise body sculpting.

/um-BIL-ih-kus/

The medical term for the navel or belly button. A common reference point in abdominal liposuction and often used as a cannula insertion site due to the natural concealment of the small scar within the navel.

/VAY-zer/

A specific ultrasound-assisted liposuction system that uses pulsed ultrasound energy to selectively emulsify fat while preserving surrounding tissue. VASER is widely used for high-definition body contouring and in areas where precision is important.

/vay-zoh-kon-STRIK-shun/

The narrowing of blood vessels, which reduces blood flow. Epinephrine in the tumescent solution causes vasoconstriction in the treatment area, dramatically reducing blood loss during liposuction. This is one of the most important safety mechanisms in modern liposuction.

/VEE-tee-ee/

A condition encompassing both deep vein thrombosis (DVT — blood clot in a deep vein) and pulmonary embolism (PE — blood clot blocking a lung artery). VTE occurs in approximately 0.017–0.06% of liposuction patients, depending on the study. Risk factors include higher BMI, combined procedures, general anesthesia, longer operative time, and personal or family history of blood clots. VTE is the most common cause of serious morbidity and mortality after liposuction.

Fat stored around internal organs within the abdominal cavity (as opposed to subcutaneous fat beneath the skin). Visceral fat cannot be removed by liposuction. It is reduced through diet, exercise, and weight loss. Patients with a large proportion of visceral fat may not see dramatic contour improvement from liposuction despite appearing to have large abdomens.

A technique using a pressurised stream of water (saline) to dislodge and remove fat cells. The BodyJet system is the primary WAL device. Claims gentler fat removal and better fat viability for fat transfer procedures. May result in less tissue trauma than traditional methods.

A liposuction technique in which a small volume of fluid (100–300 mL per treatment area) is injected before fat suctioning. The wet technique uses less fluid than the tumescent or superwet techniques and is less commonly used today, as the tumescent technique provides superior anesthesia and blood loss reduction.

The fluid injected into treatment areas before liposuction, typically containing saline, lidocaine (anesthetic), and epinephrine (to reduce bleeding). Different techniques use varying amounts: tumescent uses 2–3 mL per mL of fat to be removed; superwet uses a 1:1 ratio; wet technique uses less.

The reopening or separation of a surgical wound. Wound disruption was found to be the second most common complication in a 246,119-patient national analysis (20% of all complications) and was associated with the longest median procedure durations.

An anatomical area where the skin is naturally tightly bound to the underlying tissue by dense fibrous attachments. Aggressive liposuction in zones of adherence can cause contour deformities, depressions, or skin irregularities. Experienced liposuction surgeons identify and respect zones of adherence to achieve natural-looking results.
