ABDOMINOPLASTY & THIGH LIFT Liposuction for localised fat deposits and thick subcutaneous fat layers Excisional lifting for significant laxity of skin and soft tissues Occasionally, combination of both techniques needed Don’t forget body contouring is three-dimensional Consider effect of altering one aesthetic unit on others Indications for trunk and thigh lifts: 1) Skin laxity without significant fat deposits 2) Excessive skin laxity and cellulite 3) Patients where skin tightening is primary goal 4) Medial thigh deformities in over 35s 5) Buttock ptosis Lifts can be used either at time of initial liposuction or deformities that appear after SURGICAL OPTIONS FOR ABDOMINOPLASTY 1) LIPOSUCTION ONLY Localised deformity Satisfactory skin turgor – primary determinant of success Potential for skin to contract after suctioning 2) TRADITIONAL ABDOMINOPLASTY Deformity above and below umbilicus 3) MINI-ABDOMINOPLASTY Deformity below umbilicus 4) FLANKPLASTY 5) ENDOSCOPIC ABDOMINOPLASTY PATIENT SELECTION Age no barrier – liposuction into 80s Aspirin and anti-inflammatory agents- discontinue 2 weeks before surgery Smoking – stop 2 weeks before surgery Classfication (sugested by Glazer) Group 1 Good skin turgor Small amount fat deposit Usually liposuction in one stage good result Usually under 30 years Group 2 Skin good to mild turgor No eveidence flaccidity Moderate to localised fat deposits Liposuction in one or two stages Usually 40s or under if weight loss Group 3 Skin faccidity Fat deposits in increased volumes Usually surgery followed by liposuction Group 4 Patients with skin laxity No fat deposits 50 – 65 years or younger if massive weight loss Surgery only solution COMPLICATIONS Grazer & Goldwyn 1977 1)Seroma 2)Wound infection 3)Wound separation 4)Haematoma 5)Nerve damage Some is inevitable Mostly transitory and sensory Small areas of permanent anaesthesia around and below umbilicus 6)Pulmonary fat embolism 7)Thromboembolism – one in 100 patients develop serious thromboembolic problem Approx 1 in1000 die Grazer uses standard 5% dextrose & 5% alcohol IV solution Contains 50g alcohol administered 30 mins – 3 hours Prevents breakdown of free fat to fatty acids (which lodge in lungs and produce fat embolism) Stimulates formation of tPA prostacyclin (anti-platelet, antithrombolic) 8)Skin and subcutaneous tissue necrosis – keep patient well hydrated 9)Hypovolaemic shock Floros & Davis 1991 (BJPS) – 6 year retrospective 133 abdominoplasties; 34 followed up long term 2 groups : Group A 34 patients who atended review Group B – remaining patients surveyed through records only Results Type of Complication Group A(%) Group B(%) Infection Stitch abscess Skin necrosis Oedema Wound dehiscence Haematoma Seroma Nerve injury

third cases) No evidence that specific surgical technique is to blame In both groups, SMOKERS haad twice as many complications with skin necrosis, wound dehiscence or infection Two diabetics had infection and seromas Overall complication rate 34.6% Difference between groups really nerve injury and it may be that this is not detected early in follow up SURGICAL TECHNIQUES ISOLATED FLANKPLASTY Specific procedure to reduce flank volume, to lift or reduce buttock and to leave skin in tightened or firm condition Extended fusiform skin and subcutaneous fat resection along the flank long axis Uses ant and post iliac spine as reference Resection takes all skin and sc tissue down to muscular fascia Pinch test with patient standing best way to estimate amount of resection Skin and fat dissection limited to what should be resected – no undermining done If limited resection, post suture may stop at different distances from post mid-line If buttocks and thighs involved, include extensive undermining in affected regions Buttocks and lateral femoral skin undermined at fascial layer to allow all of skin flaps to lift SUCTIONING ABDOMEN ONLY Less than 750 mls can be done under local Grazer uses “lipocrit” to determine blood loss and need for replacement Stab incisions in groin, inguinal crease or periumbilical area FULL ABDOMINOPLASTY Basic principles: 1) Incision – standard transverse lower abdominal incision 2) Elevation of panniculus & decision whether to use liposuction Wide undermining of abdominal flap to costal margins 3) Plication of diastasis recti 4) Closure Resection of redundant abdominal flap Skin closure with hips flexed 5) Tailoring of umbilicus 6) Suctioning of upper abdomen if indicated 7) Suctioning of adjacent deformities 8) Trimming of flaps and dog-ears 9) Drains and dressings 1) Incision selection Patient body type Bathing suits If long waisted, may not be possible to obliterate umbilicus & inverted T is used Historically, several different incisions used Baroudi (1987) bicycle handlebar incision Recent inverted W 2) Elevation of panniculus Can suction either before or after panniculus is elevated Elevate with electrodissection Circumscript umbilicus Elevate or xiphoid and costal margins 3) Plication of recti Non-absorbable suture for first layer of closure Then running layer of absorbable – avoids palpable knots 4) Closure Patient in flexed position Vertical cuts made to fit panniculus Excess tissue resected Panniculus pulled down and tacked into position 5) Tailoring umbilicus Position about 15 to 17 cm from vulvular ant commissure Beforehand, suction median raphe to give more youthful appearance Vertical incision through skin to make opening for umbilicus Can use this opening to suction through Suture abdominal skin to rectus fascia at 3, 6 and 9 o’clock positions (prevents umbilicus being pulled back into wound) No 12 o’clock suture means no hooding – as a youthful umbilicus Suture remainder 6) Suctioning of upper abdomen Controversial issue, since possible compromise of upper skin flap Smaller cannulas reduce risk 7) Suctioning of adjacent deformities Esp hips and flanks Can also suction medial thigh 6) Trimming of flaps and dog ears If high umbilicus, which doesn’t extend beyond transverse pubic scar when flap pulled down, then can compensate with small vertical scar ?use of quilting sutures for undermined regions Makes a smoother more refined incision line 8) Drains and dressings Two drains stab incision in mons pubis or through incision itself Supportive garment – Velcro abdominal binder MINI-ABDOMINOPLASTY Less extensive operation Indicated if deformity primarily below umbilicus Choice of incision essentially same as for full abdominoplasty – lateral extent of incision is not as long Suction entire abdominal wall before elevation After elevation to umbilicus, can determine if plication is necessary Same suturing technique as for full abdominoplasty Can extend dissection 3-4cm above umbilicus for putting plication sutures above umbilicus Final closure as before Same aftercare ENDOSCOPIC ABDOMINOPLASTY Potential Benefits: 1) Decreased scarring 2) Extended reach Allows entire abdo fascial surface to be exposed through single incision 3) Excellent visualisation 4) Surgeon positioning 5) Preservation of anatomical structures Skin incisions and dissection limited eg. superficial inferior epigastric vessels 6) Augmented flap vascularity Vessels preserved No skin excision so no tension on wound 7) Decreased morbidity Shown with other endoscopic abdo procedures Patient Selection: Little or no excess skin Mild or moderate amounts of fat can be liposuctioned Supraumbilical laxity can be corrected also by this technique REVERSE ABDOMINOPLASTY Deformity (including surgical scars) confined to upper abdomen Incision in upper abdominal region under infra-mammary fold Can be done with breast reduction as a combined procedure COMBINED PROCEDURES Combined procedures with abdominoplasty not resulted in increased morbidity if patient selection appropriate and autologous blood available MEN Body deformities differ in men Localised fat deposits commonly chest, abdomen, flanks, back, medial thighs Skin and soft tissue laxity occur in lower abdomen, medial thighs, chest Rarely have laxity problems in anterior or lateral thighs POST-OPERATIVE MANAGEMENT Flexed position on day of surgery Mobile 24 hours following surgery Semi-flexed position for 24 hours Suctioned patients don’t have to be flexed Removal of drain 24 – 48 hours Velcro binder for 2 – 3 weeks after surgery Prophylactic antibiotics Ultrasound may help resolve lumps and eccymoses Given a few days post surgery depending on patient’s level of comfort Twice a week for 2 – 3 weeks Resume normal activity in 3 – 4 weeks For suction alone this is when eccymosis and oedema subsides 4-6 weeks before aerobics REVISION PROCEDURES Suction techniques not recommended earlier than 4 months post operatively Following abdominoplasty, preferable to wait 6 months to a year Steroid injections for hypertrophic scars EXCIONAL LIFTING (LOCKWOOD) Aesthetic Abdominal Features (Lockwood) 1) Tight lateral trunk and inguinal tissues with deep waist concavity 2) Central tissues not tight with mild convexity of hypogastrium and mild concavity of epigastrium 3) Midline epigastrium valley between rectus muscle bulges 4) Vertically orientated umbilicus 5) Vertical valley lateral to rectus muscle bulges below costal margins 6) Smooth, gentle, S-shaped outlines of anterior and lateral silhouette Consider aesthetic relationship of hypogastrium and pubis In women, vertical distance between umbilicus and exc vulvular commissure should be 60% non-hair bearing (hypogastrium) and 40% hair bearing (mons pubis) In addition to resection of lower abdominal tissue, the stretched vertical height of the mons pubis may have to be shortened to meet these aesthetic goals. In men, the vertical distance between umbilicus and base of penis should be 70% hypogastric and 30% pubic tissue. Classic abdominoplasty based on two theoretical principles which may be proved inaccurate 1) wide direct undermining to costal cartilages is essential for abdominal flap advancement In fact, discontinuous undermining allows effective loosening of abdominal flap while preserving vascular perforators/ 2)assumed that with ageing and weight fluctuations (incl pregnancy abdominal skin relaxation occurs primarily in the vertical direction from the xiphoid to the pubis This is true in lower abdomen, but in most people a strong superficial fascial system (SFS) adherence to linea alba in epigastrium limits vertical descent Epigastric laxity frequently results from a progressive horizontal loosening due to relaxation of the tissues along the lateral trunk. Standard abdominoplasty tightens centrally, thus increasing laxity laterally Wide undermining prevents circumferential liposuction High lateral tension abdominoplasty designed to produce more aesthetic body contours KEY TECHNICAL POINTS (Plast Reconstr Surg 96: 603, 1995) 1) Direct undermining limited to the paramedian area 2) Discontinuous undermining to costal margins and flanks as needed 3) Skin resection pattern with significant lateral resection 4) Highest-tension wound closure placed laterally 5) Superficial fascial system repair with permanent sutures along the entire incision 2) Liberal use of adjunctive liposuction in upper abdomen and lateral and posterior trunk Thus only perforators cut when plicating rectus Other perforators preserved thus allowing more liposuction Advantages: High tension laterally: More natural abdominal contours Strong lift of lax inguinal tissues Mild lift of ant medial thigh tissues Decreases tension on suprapubic wound closure (reducing risk of skin necrosis and superior migration of pubic hair) SFS suspension with permanent sutures: More natural contour lines Late suprapubic depression eliminated Disadvantages of high tension laterally: Tendency for dog-ear formation due to quick transition from high tension in inguinal area to usual laxity of lateral trunk May require minimal lengthening of abdominoplasty incision Patient Selection: Designed as alternative to standard abdominoplasty so same patient selection Ie. where soft tissue laxity is a major component Pre-op markings with patient standing Short horizontal suprapubic line that angles towards ASIS then curves horizontally, but maintained in bikini outline Amount of inguinal laxity inferior to this is then marked (initial incision line) When sutured, inguinal flap elevates only to proposed line of closure due to tethering effect of SFS zone Exact amount of resection determined at end of procedure, although can be estimated Localised fat deposits marked for liposuction Operative Technique Inferior anchor resection line incised Inferior abdomen undermined to umbilicus If umbilicus not to be transposed, stalk is resected for better exposure and later resutured to muscle fascia 1-2cm below original position Direct undermining superior to umbilicus limited to medial rectus border to allow muscle plication Discontinuous undermining of remaining abdomen performed with vertical-spreading scissor dissection Table flexed to 30 degrees and redundant abdominal flap resected Max tension placed along lateral incision limbs Haemostasis Any restricting fibrous septae dimpling skin released deeply Drains brought out through mons pubis 3-layer wound closure Umbilicoplasty MEDIAL THIGH LIFT (Lockwood) Skin laxity in medial thigh is often earliest sign of ageing in thighs Skin of medial thigh is thin and inelastic By 35 years, skin laxity usually means disappointing results by liposuction alone Classical medial thigh lift problems: Inferior migration and widening of scars Lateral traction deformity of vulva Early recurrence of ptosis Modifications: Modified to allow anchoring of inferior skin flap to the tough, inelastic deep layer of the superficial fascia of perineum Using Colles fascia as central anchor for medial thigh lift has produced more consistent, longer lasting results Indication: significant actual or potential laxity of medial thigh tissues Liposuction often leads to skin relaxation, esp after age 30 years Majority of skin laxity occurs at junction of anterior and medial thighs Modification has rotated the standard surgical resection pattern anteriorly, allowing entire procedure to be performed in supine position Incision should not extend to buttock fold posteriorly Markings: In standing position with knees apart Extent of medial fat thigh deposits marked Estimate amount of skin redundancy Actual resection averages 5 – 7cm stretched skin at anteromedial corner of thigh Anchoring of perineal-thigh crease into Colles fascia provides additional 3-5cm of lift Operative Technique: Patients supine with hips flexed to 20 – 30 degrees Stockinettes placed to knees Excision of redundant tissue and subsequent repair performed with knees shoulderwidth apart Initial deep liposuction followed by skin-only incision along superior resection line After skin incision, undermine inferior flap posterior to pubic tubercle Undermining extends 3-4 cm beyond planned line of resection Undermining is post to pubic tubercle and superficial to adductor muscle fascia Cannulae undermining more distal may be helpful for laxity problems extending to knee Take care of soft tissue between mons pubis and femoral triangle Superficial undermining here preserves ext. pudendal blood and lymphatic vessels Blunt dissection through this bundle at mons exposes Scarpa’s fascia or muscular fascia which can be used to anchor thigh flap in pubic region Once flap undermining complete, identify Colles’ fascial roll Permanent anchoring sutures used Scarpa’s fascia is used as anchor anteriorly and buttock-fold SF post Drains generally not used Complications Delayed wound healing (30%) Scar widening and migration (due primarily to over-resection) Wound infection Transient perineal lymphoedema Persistent deformity due to inadequate resection Thigh paraesthesia/anaesthesia , which improves over 1 year TRANSVERSE THIGH/BUTTOCK LIFT Classic is Pitanguy lift (1964) Allows direct excision of trochanteric fat deposits Also used for laxity of lateral thigh and buttock However problems of noticeable scars and early recurrence of deformities Lockwood: Transverse resection of redundant skin and fat of trunk with incisional scar within high-cut bikini lines Can be used alone or in combination Operative Technique: Markings made standing in high cut bikini line Amount of soft tissue redundancy superior to planned line is iestimated (knees 6 in apart) Usually 4-5cm – about ¼ of vertical excess along lat body Redundant tissue inferior to planned line is estimated Usually 10-15cm vertically along lateral contour Patient in lateral decubitus position Hip flexed anteriorly to 30-45 degrees (overcorrection) Thighs abducted with foam blocks to keep knees 15 in apart Liposuction of trochanteric and post thigh deposits if needed Incision through superior resection line Undermining along lateral countour just superficial to muscle fascia, staying lateral to femoral triangle lymphatics Undermining then sweeps posteriorly over deep fat of buttocks Direct undermining should extend beneath flap to be resected and into trochanteric region, releasing SFS zone of adherence that extends from lateral gluteal recess around to femoral triangle lymphatics No direct or discontinous undermining performed over buttocks Discontinous cannulae undermining is performed more distally if aesthetic deformit extends into lower half of thigh Redundant soft tissue now resected Drains Post op compression garment Hips flexed post op 20-30 degrees and thighs abducted 1-2 weeks to reduce wound tneison
