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.

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.

Background The recent rise in popularity of minimally invasive facial aesthetic procedures has resulted in the overall heightened patient interest in lip rejuvenation. There is a variety of techniques and modifications for surgical upper lip enhancement described in the literature but no single method is considered optimal. The aim of this literature review is to provide a comprehensive analysis of the studies dealing with surgical upper lip enhancement and evaluate their short- and long-term outcomes, as well as complication profiles. Methods A comprehensive review of the published literature through July of 2019 was performed. The PUBMED and Cochrane databases were searched for all English language articles on aesthetic surgical enhancement of the upper lip. Only articles dealing with the aesthetic aspect of the upper lip subunit were included. Preoperative assessment, patient selection and technique execution were assessed. Data were abstracted on all postoperative complications and outcomes. Results Overall, 52 articles were screened for inclusion, of which 17 met the inclusion criteria. The total number of patients treated in these studies was 2265. The average follow-up period was 30 months. The most commonly used surgical method across the studies was the subnasal lip lift (93.6%). The bull’s horn excision pattern was utilized to perform the subnasal lip lift in 71.7% of the cases, and the wavy ellipse excision was used in 18.1% of patients. Lip advancement by vermillion border excision pattern was the technique of choice for 49 patients (2.2%). Across all patients the most common complication was a non-aesthetically appealing result or adverse scarring with a mean incidence of 7.23%. Overall, the studies reported improvement in the aesthetic appearance of the upper lip after surgical enhancement, along with few but promising reports of high patient satisfaction. There is a relative paucity of high-quality data regarding complication profiles, patient selection, indications and contraindications. Conclusions This review provides an overview of several techniques and modifications for upper lip enhancement. It highlights the paucity of high-quality data on their application and optimizing patient selection. Promising satisfaction rates and relatively low complication rates suggest a more prominent role for surgical cheiloplasty in facial rejuvenation.

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.

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.

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.

Background: Venous thromboembolism (VTE) chemoprophylaxis warrants an individualized, risk-stratified approach, and constitutes a relatively controversial topic in plastic surgery. Objectives: The aim of this study was to determine the safety of a 7-day postoperative enoxaparin regimen for VTE prophylaxis compared with a single preoperative dose of heparin in abdominal body contouring surgery. Methods: This single-institution pre-post study investigated the safety of a 7-day enoxaparin postoperative regimen in abdominal body contouring procedures performed by a single surgeon from 2007 to 2018. Four procedures were included: traditional panniculectomy, abdominoplasty, fleur-de-lis panniculectomy, and body contouring liposuction. Group I patients received a single dose of 5000 U subcutaneous heparin in the preoperative period, and no postoperative chemical prophylaxis was administered. Group II patients received 40 mg subcutaneous enoxaparin in the immediate preoperative period, then once daily for 7 days postoperatively. Results: A total of 195 patients were included in the study, 66 in Group I and 129 in Group II. The groups demonstrated statistically similar VTE risk profiles, based on the 2005 Caprini risk-assessment model. There were no statistically significant differences in the 2 primary outcomes: postoperative bleeding and VTE events. Group I patients had higher reoperation rates (22.7% vs 10.1%, P = 0.029), which was secondary to higher rates of revision procedures. Conclusions: A 7-day postoperative course of once-daily enoxaparin for VTE risk reduction in abdominal body contouring surgery does not significantly increase the risk of bleeding. Implementation of this regimen for postdischarge chemoprophylaxis, when indicated following individualized risk stratification, is appropriate. Level of Evidence: 4:

Background: There is no consensus on the optimal operative treatment of isolated closed metacarpal fractures as every technique is associated with advantages and shortcomings. This retrospective study aims to compare the outcomes of single metacarpal, extra-articular fractures treated with closed reduction and percutaneous pinning (CRPP) versus open reduction and internal fixation (ORIF). Methods: The charts of all patients who underwent surgical repair of closed metacarpal fractures at our institutions from 2009 to 2016 were reviewed. 70 patients met the inclusion criteria, 44 had undergone CRPP and 26 ORIF with plate or lag screws. Subgroup analyses of all patients stratified by both fracture pattern and fracture location were performed. Additionally, subgroup analyses of outcomes based on the time from injury to surgery were conducted. Clinical outcomes included immobilization time, total active motion, stiffness, complication and reoperation rates, as well as occupational therapy referral rates and duration. Functional outcomes were determined using the Quick-DASH (Disabilities of the Arm, Shoulder and Hand) score via telephone questionnaire administered retrospectively. Results: Overall, there was no significant difference in functional outcome parameters including total active motion (CRPP 91% of normal vs. ORIF 87% of normal), stiffness, therapy referrals, and complications between treatment groups. Patients treated with CRPP, regardless of fracture pattern or location, were operated on earlier than those treated with ORIF (avg. 7 days vs. 15 days). The immobilization time for patients treated with ORIF was significantly less than those treated with CRPP (19.7 vs. 30.7 days; p=0.001). This difference in the immobilization time also reflected the outcomes of the subgroup analyses based on the post-injury time of surgery. When transverse shaft fractures were examined independently as a subgroup, ORIF resulted in improved post-operative range of motion vs. CRPP (100% normal vs. 91% normal). The mean DASH score for each group was satisfactory and the difference was not statistically significant (16.3 for the CRPP and 18.7 for the ORIF group, p=0.805). Conclusion: Both CRPP and ORIF are viable techniques with good clinical outcomes and low complication rates. ORIF of closed metacarpal fractures allowed for earlier mobilization when compared with CRPP without compromising fracture stability, clinical or functional short-term outcomes.
