The Effect of Obesity, Bariatric Surgery, and Operative Time on Abdominal Body Contouring Outcomes.

BACKGROUND: Abdominal body contouring procedures are associated with the highest rates of complications among all aesthetic procedures. Patient selection and optimization of surgical variables are crucial in reducing morbidity and complications. OBJECTIVES: The purpose of this single-institution study was to assess complication rates, and to evaluate BMI, operative time, and history of bariatric surgery as individual risk factors in abdominal body contouring surgery. METHODS: A retrospective chart review was performed of all patients who underwent abdominoplasty, circumferential lower body lift, fleur-de-lis panniculectomy (FDL), and circumferential FDL between August 2014 and February 2020. Endpoints were the incidence of venous thromboembolism, bleeding events, seroma, infection, wound complications, and reoperations. Univariate statistical analysis and multivariate logistic regressions were performed. Covariates in the multivariate logistic regression were BMI, procedure time, and history of bariatric surgery. RESULTS: A total of 632 patients were included in the study. Univariate analysis revealed that longer procedure time was associated with infection (P = 0.0008), seroma (P = 0.002), necrosis/dehiscence (P = 0.01), and reoperation (P = 0.002). These associations persisted following multivariate analyses. There was a trend toward history of bariatric surgery being associated with minor reoperation (P = 0.054). No significant increase in the incidence of major reoperation was found in association with overweight or obese patient habitus, history of bariatric surgery, or prolonged procedure time. BMI was not found to be an individual risk factor for morbidity in this patient population. CONCLUSIONS: In abdominal body contouring surgery, surgery lasting longer than 6 hours is associated with higher incidence of seroma and infectious complications, as well as higher rates of minor reoperation.

Safety of Rivaroxaban for Postoperative Venous Thromboembolism Prophylaxis Following Abdominal Body Contouring Surgery: 600 Patients.

BACKGROUND: Reducing the incidence of venous thromboembolism (VTE) following abdominal body contouring surgery remains a top priority for patient safety. There is a lack of consensus regarding the optimal chemoprophylactic agent for postoperative VTE prophylaxis, and the role of oral anticoagulants warrants further investigation. OBJECTIVES: The aim of this multisurgeon, single-institution study was to determine the safety and efficacy of a 7-day postoperative rivaroxaban regimen for VTE prophylaxis in abdominal body contouring surgery. METHODS: A retrospective chart review was performed of all patients who underwent abdominoplasty, circumferential body lift, fleur-de-lis panniculectomy, or circumferential fleur-de-lis panniculectomy at our surgical center from August 2014 to November 2019. A 7-day postoperative course of once-daily 10 mg rivaroxaban, starting on postoperative day 1, was administered to every patient unless there was a contraindication. The 2 primary endpoints were the incidence of VTE and bleeding events. RESULTS: A total of 600 patients were included in the study. There were no deaths. There were 4 (0.7%) incidents of VTE events: 2 (0.3%) patients suffered pulmonary embolus and 2 (0.3%) patients suffered a lower-extremity deep venous thrombosis. A total of 13 (2.2%) patients suffered complications related to bleeding. Of these, operative intervention for control and evacuation was required in 7 (1.2%) patients. CONCLUSIONS: A 7-day postoperative course of once-daily rivaroxaban for VTE risk reduction in abdominal body contouring surgery is associated with a low incidence of VTE events and a low risk of bleeding complications.

Avulsion Fat Graft Gluteoplasty: Technique Overview.

BACKGROUND: The popularity of gluteoplasty has grown significantly in recent years, and there are a variety of techniques described to address gluteal aesthetic deformities. The aim of this study was to describe the avulsion fat graft gluteoplasty technique. METHODS: A review of all consecutive patients undergone avulsion fat graft gluteoplasty from February 2018 to March 2019 was performed. Data included demographics, operative details, and clinical outcomes. RESULTS: A total of 7 patients with a minimum of 6 months follow-up were analyzed and included in the study. The avulsion fat graft gluteoplasty technique is described in a step-by-step fashion and illustrated by preoperative, postoperative, and intraoperative photographs, as well as video. The average total weight of the avulsed specimen was 372 g (range, 176-596 g) per patient. The average total volume of fat grafting was 593 mL (range, 344-900 mL) per patient. CONCLUSIONS: The avulsion fat graft gluteoplasty is a powerful technique with consistent results and low-risk profile. It provides durable lift and augmentation and produces a predictable and aesthetic scar.

The Three-Triangle Rotation Flap Technique for Aesthetic Ear Lobule Reduction.

BACKGROUND: Although the effect of normal aging on the appearance of the ear lobule is well known and defined, this often a neglected aspect of facial rejuvenation. Rhytidectomy offers a great opportunity to surgically enhance the aging earlobe. The objective of this study was to provide a step-by-step description of the execution of the three-triangle rotation flap technique for aesthetic ear lobule reduction. METHODS: The three-triangle rotation flap technique is described in a step-by-step fashion and illustrated by photographs and videos. All ear lobule reduction procedures that took place at our practice from December 2016 to February 2020 were retrospectively reviewed. RESULTS: A total of 16 patients underwent bilateral ear lobule reduction during face lift, neck lift, or both, and 7 patients underwent bilateral lobule reduction in isolation. None of the patients experienced complications, and revisions were not performed or required. CONCLUSIONS: The three-triangle rotation flap technique relies on simple principles that can be adjusted to address all shapes and degrees of true ear lobule ptosis, as well as patient desire. It is employed in isolation or synchronous with rhytidectomy. When performed during rhytidectomy, it provides lobule stability and fixation.

Four-Position Four-Entry Site Circumferential Arm Liposuction: Technique Overview and Experience.

BACKGROUND: In attempting to overcome the challenges associated with arm contouring, arm liposuction has been an area of focus in recent years. In appropriately selected patients, circumferential liposuction is the procedure of choice. The objective of this study is to describe our experience with the four-position four-entry site circumferential arm liposuction technique. METHODS: All consecutive circumferential liposuction procedures that took place at our ambulatory surgical facility from January 2015 to November 2019 were retrospectively reviewed. The four-position four-entry site circumferential arm liposuction technique is described, and photographs as well as videos are presented. RESULTS: A total of 35 patients underwent circumferential bilateral arm liposuction via the four-position four-entry site technique. All patients were female, and their average age was 43 years. The average BMI was 28.4 kg/m2, and the average follow-up was 481 days. The average volume of lipoaspirate was 1,514 ml per patient, and the average volume of aspirated fat was 1,052 ml per patient. There was no incident of infection, seroma, bleeding event or venous thromboembolism. CONCLUSIONS: For the right candidate, the four-entry site four-position circumferential arm liposuction is an efficient and reproducible technique, which produces predictable and pleasing results.

A Multicenter, Prospective, Randomized, Contralateral Study of Tissue Liquefaction Liposuction vs Suction-Assisted Liposuction.

BACKGROUND: Tissue liquefaction liposuction (TLL) deploys a novel energy source utilizing a stream of warmed, low-pressurized, and pulsed saline to extract fat tissue. OBJECTIVES: Compare TLL to suction-assisted liposuction (SAL) to determine which device is more efficient for surgeons and provides better recovery for patients. METHODS: Thirty-one adult female patients were followed prospectively in a contralateral study design comparing differences in bruising, swelling, tenderness, and incision appearance ratings between TLL and SAL procedures. Surgical efficiency and appearance of the lipoaspirate were also compared. RESULTS: All 31 patients successfully completed the study. For TLL and SAL procedures, the average volumes of infusion (1.242 vs 1.276 L) and aspirated supernatant fat (704 vs 649 mL) were statistically similar. TLL median fat extraction rate was faster than SAL (35.6 vs 25 mL/min; P < 0.0001), and stroke rate was reduced in TLL vs SAL procedures (48 vs 120 strokes/min; P < 0.0001), and both were statistically significant. The mean total scores for bruising, swelling, treatment site tenderness, and incision appearance were lower, indicating improved patient recovery on the TLL side. CONCLUSIONS: TLL and SAL techniques produced comparable volume of fat aspirate. TLL demonstrated a 42% faster fat extraction rate and a 68% reduction in arm movements needed to complete the procedure compared to SAL, both of these differences are statistically significant. The TLL side was noted to have reduced bruising and swelling and improved incision site appearance with less tenderness compared to the SAL side.

Rivaroxaban for Venous Thromboembolism Prophylaxis in Abdominoplasty: A Multicenter Experience.

BACKGROUND: Abdominoplasty, a commonly performed aesthetic procedure, is considered to have an increased risk of venous thromboembolism (VTE) events. At present, routine VTE chemoprophylaxis following abdominoplasty remains controversial. OBJECTIVES: This study evaluates the authors' experience with rivaroxaban, an oral Factor Xa inhibitor, for VTE prophylaxis in abdominoplasty patients. METHODS: A retrospective case series was conducted. All patients who underwent abdominoplasty and received rivaroxaban were included. The prophylactic dose was 10 mg daily for 7 days, beginning 12 hours postoperatively. Patient demographics, comorbidities, and type of surgery were recorded. The primary outcome measured was hematologic complication, including VTE, hematoma requiring operative evacuation, and need for blood transfusion. RESULTS: From September 2012 until July 2014, 132 patients (122 women and 10 men) underwent abdominoplasty surgery and received rivaroxaban postoperatively. Mean patient age was 43.7 years, and mean body mass index was 27.1. One hundred twenty-five patients also underwent abdominal muscle plication. Eleven patients underwent a fleur de lis vertical skin resection component. One hundred patients underwent concomitant abdominal liposuction, while 79 patients also had back liposuction. Only 1 patient had a symptomatic VTE event. Three patients had a hematoma requiring operative evacuation, and all went on to heal without sequelae. Two patients received a blood transfusion for anemia during their course of rivaroxaban. CONCLUSIONS: Oral rivaroxaban administration for chemoprophylaxis in abdominoplasty patients is safe, with low rates of symptomatic VTE and hematoma formation. The authors continue routine use of the medication for patients at increased risk for VTE events. LEVEL OF EVIDENCE 4: Risk.

A Multicenter Study for Cellulite Treatment Using a 1440-nm Nd:YAG Wavelength Laser with Side-Firing Fiber.

BACKGROUND: Treatment of cellulite using a 1440-nm YAG wavelength laser with side-firing fiber has proven safe and effective, lasting at least 6 months. OBJECTIVES: The authors evaluate the safety and efficacy of a single, subdermal procedure to treat the underlying structure of cellulite for at least 1 year. METHODS: Fifty-seven patients underwent a 3-step cellulite treatment with a 1440-nm Nd:YAG laser with a side-firing fiber and temperature-sensing cannula. Efficacy was measured by the blinded evaluators to distinguish baseline photos from those taken at 12 months posttreatment, with results on a 5-point, 2-category ordinal photonumeric scale when comparing baseline photos to 12 months posttreatment. Subject and physician satisfaction was assessed based on completion of a satisfaction survey. Adverse events (AE) were recorded throughout the study. Twelve month data were analyzed and compared to 6 month data. RESULTS: Evaluators chose baseline photographs 97% on average from 6 (-1, +2) months and 91% from the 12 (-3, +2) months posttreatment photographs. At 6 (-1, +2) months, the average improvement score was 1.7 for dimples and 1.1 for contour irregularities. At 12 (-3, +2) months, the average improvement score was 1.4 for dimples and 1.0 for contour irregularities. The average satisfaction score for the physician was 5.6 and the patient was 5.3 on a 6-point scale. CONCLUSIONS: A single, 3-step, minimally invasive laser treatment using a 1440-nm Nd:YAG laser, side-firing fiber, and temperature-sensing cannula to treat the underlying structure of cellulite proved to be safe and maintained effectiveness at least 1 year post treatment. LEVEL OF EVIDENCE 2: Therapeutic.

A Prospective, Randomized, Multicenter Trial Assessing a Novel Lysine-Derived Urethane Adhesive in a Large Flap Surgical Procedure without Drains.

OBJECTIVE: To evaluate the safety and effectiveness of a lysine-derived urethane adhesive as a noninvasive alternative to closed suction drains in a commonly performed large flap surgical procedure. METHODS: One hundred thirty subjects undergoing abdominoplasty at five centers were prospectively randomized to standard flap closure with surgical drains (Control group) or a lysine-derived urethane adhesive (Treatment group) without drains. The primary outcome measured was the number of post-operative procedures, including drain removals (as the event marking the use of a surgical drain) and needle aspirations. Secondary endpoints included total wound drainage, cumulative days of treatment, and days to drain removal. A patient questionnaire evaluating quality of life measures was also administered. RESULTS: Subjects in the Treatment group required significantly fewer post-operative procedures compared to the Control group (1.8 ± 3.8 vs. 2.4 ± 1.2 procedures; p < 0.0001) and fewer cumulative days of treatment (1.6 ± 0.4 vs. 7.3 ± 3.3; p < 0.0001). A procedure to address fluid accumulation was required for only 27.3 % of the subjects in the Treatment group versus 100 % of Control group, which by study design required the use of drains. The mean duration of use of indwelling surgical drains for the Control group was 6.9 ± 3.3 days. All fluid collections treated with percutaneous aspiration were resolved and there were no unanticipated adverse events. CONCLUSION: The results of the study support that the use of a lysine-derived urethane adhesive is a safe and effective alternative to drains in patients undergoing a common large flap surgical procedure.

A multicenter randomized controlled trial comparing absorbable barbed sutures versus conventional absorbable sutures for dermal closure in open surgical procedures.

BACKGROUND: Barbed sutures were developed to reduce operative time and improve security of wound closure. OBJECTIVE: The authors compare absorbable barbed sutures (V-Loc, Covidien, Mansfield, Massachusetts) with conventional (smooth) absorbable sutures for soft tissue approximation. METHOD: A prospective multicenter randomized study comparing barbed sutures with smooth sutures was undertaken between August 13, 2009, and January 31, 2010, in 241 patients undergoing abdominoplasty, mastopexy, and reduction mammaplasty. Each patient received barbed sutures on 1 side of the body, with deep dermal sutures eliminated or reduced. Smooth sutures with deep dermal and subcuticular closure were used on the other side as a control. The primary endpoint was dermal closure time. Safety was assessed through adverse event reporting through a 12-week follow-up. RESULTS: A total of 229 patients were ultimately treated (115 with slow-absorbing polymer and 114 with rapid-absorbing polymer). Mean dermal closure time was significantly quicker with the barbed suture compared with the smooth suture (12.0 vs 19.2 minutes; P<.001), primarily due to the need for fewer deep dermal sutures. The rapid-absorbing barbed suture showed a complication profile equivalent to the smooth suture, while the slow-absorbing barbed suture had a higher incidence of minor suture extrusion. CONCLUSIONS: Barbed sutures enabled faster dermal closure quicker than smooth sutures, with a comparable complication profile. LEVEL OF EVIDENCE: 1.

A multicenter study for a single, three-step laser treatment for cellulite using a 1440-nm Nd:YAG laser, a novel side-firing fiber, and a temperature-sensing cannula.

BACKGROUND: Historically, treatments for cellulite have not been able to address all of its physiological components and require multiple sessions. OBJECTIVE: The authors evaluate the safety and efficacy of a single, subdermal procedure to treat the underlying structure of cellulite. METHODS: Fifty-seven patients underwent a 3-step cellulite treatment with a 1440-nm Nd:YAG laser with a side-firing fiber and temperature-sensing cannula. Efficacy was measured by the ability of blinded evaluators to distinguish baseline photos from those taken at 3 and 6 months posttreatment, as well as their rating of the results on a 5-point, 2-category ordinal photonumeric scale when comparing baseline photos to those taken at 2, 3, and 6 months posttreatment. Patient and physician satisfaction was assessed based on completion of a satisfaction survey at 2, 3, and 6 months posttreatment. Adverse events (AE) were recorded throughout the study. RESULTS: At 6 months posttreatment, blinded evaluators rated at least a 1-point improvement in the appearance of cellulite in 96% of treated sites. Blinded evaluators were also able to correctly identify baseline versus posttreatment photos in 95% of cases. At least 90% of patients and physicians reported satisfaction with the results of treatment throughout 6 months. AE were mild in intensity and transient to treatment. CONCLUSIONS: A single, 3-step, minimally invasive laser treatment using a 1440-nm Nd:YAG laser, side-firing fiber, and temperature-sensing cannula to treat the underlying structure of cellulite proved to be safe and maintained effectiveness at least 6 months posttreatment. LEVEL OF EVIDENCE: 2.
