Abstract
Introduction: Aesthetic liposuction represents one of the most commonly performed cosmetic procedures worldwide. The purpose of this article is to examine and synthesize reported complication rates and explore the analytical prospect of possible patient or procedure-related predictive factors associated with specific complications. Methods: A systematic review was performed using the Pubmed, Cochrane, and Embase databases in line with specific criteria set to ensure an accurate assessment of complication rates; extracted data was synthesized through a random-effects model and meta-analysis of proportions. Results: A total of 60 studies were included in the meta-analysis, representing 21,776 patients undergoing aesthetic liposuction. Most studies followed an observational design. The overall complication rate was 12% (95% confidence interval [CI] 8%, 16%). When stratifying according to specific complications, the incidence of contour irregularities was determined to be 2% (95% CI 1%, 2%), seroma 2% (95% CI 1%; 2%), hematoma 1% (95% CI 0%, 1%), surgical site infection 1% (95% CI 1%, 2%), fibrosis or induration 1% (95% CI 1%, 2%), and pigmentary changes 1% (95% CI 1%, 1%), among others. A meta-regression to identify patient- or procedure-related factors associated with greater complication rates proved infeasible given the nature of the available data. Conclusion: Overall, liposuction demonstrated a relatively low complication rate profile, however, a considerable degree of heterogeneity exists within the examined literature preventing the recognition of predictive risk factors. While this calls for efforts to establish consensus on unified methods of outcomes reporting, the present meta-analysis can serve to provide practitioners with an evidence-based reference to improve informed consent and inform clinical guidelines, specifically pertaining to the incidence of commonly encountered complications in aesthetic liposuction, of which presently available survey studies and database queries remain devoid.

[PMID: 35567894 DOI: 10.1016/j.gaitpost.2022.05.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 02/04/2022] [Accepted: 05/04/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND The sagittal plane alignment of ankle-foot orthoses (AFO) and AFO footwear combinations (AFO-FC) has been shown to influence gait outcomes. As such, clinicians often target a particular alignment during the fabricating and fitting of an AFO to maximize outcomes. RESEARCH QUESTION How does the alignment of an AFO change during the fabrication and fitting process with respect to the intended, benchmark sagittal plane alignment identified by the consulting orthotist? STUDY DESIGN Prospective METHODS: The assessment of AFO alignment was performed using a convenience sample of 125 custom molded AFOs from 68 individuals fabricated at our center (57 bilateral AFOs, 11 unilateral AFOs). The alignment of each AFO was measured at 5 distinct steps during the fabrication and fitting process using a recently validated method to measure AFO neutral angle using differential inclinometers. RESULTS Prior to fabrication, the intended, benchmark alignment set by the consulting orthotist was 90 degrees for 92% of AFOs, was between 1 and 7 degrees of dorsiflexion for 7% of AFOs and was 5 degrees of plantarflexion for 1% of AFOs. Repeated measures ANOVA showed that AFO alignment changed between all fabrication and fitting steps. Overall, paired t-tests confirmed that AFO alignment was consistently 2-5 degrees more dorsiflexed than the benchmark alignment. Prior to fitting shoes, 55% of fabricated AFOs measured more than 2 degrees from the benchmark alignment. After fitting shoes, nearly 87% of AFO-FCs were more than 2 degrees from the benchmark alignment. SIGNIFICANCE The finding of systematic dorsiflexion bias and changes in AFO alignment throughout the fabrication and fitting process indicates the need to improve AFO fabrication precision. The neutral angle measurement methodology - using differential inclinometers - provides a means to improve this precision by enabling orthotists to precisely quantify and make appropriate adjustments to AFO alignment throughout the entire fabrication and fitting process.

Abstract
Since its inception in the 1980s, liposuction has undergone a tremendous paradigm shift from the simple removal of excess subcutaneous fat to a procedure of extreme sophistication and elegance where we as surgeons are able to mold and shape a patient's figure. Plastic surgeons have modified this procedure with the overall goal of improving the aesthetic results while focusing on maximizing safety and minimizing complications. These modifications include advanced liposuction technology and techniques, the increasing use of subdermal superficial liposuction, differential liposuction, the advent and introduction of a wide range of cannulas, and the use of fat grafting simultaneously with liposuction for targeted contour and fat repositioning. In this article, the authors discuss in detail the introduction and progression of abdominal etching, a procedure first introduced by the senior author (H.A.M.) in the early 1990s. The authors also present their experience over the past 4 years. In this procedure, the technique of differential liposuction is employed to enhance the detail of abdominal musculature. The literature on abdominal etching is fairly scarce. Thus, the authors hope that this review will not only give the provider a thorough review and understanding of liposuction and its evolution over the years but will also provide an overview of the indications, patient selection, technique, expectations, and complications of abdominal etching as well.

Abstract
Lipoedema is a rare painful disorder of the adipose tissue. It essentially affects females and is often misdiagnosed as lymphoedema or obesity. It is globally misdiagnosed or underdiagnosed, and the literature is lacking appropriate guidance to assist clinicians towards this diagnosis. However, the need to recognise this disorder as a unique entity has important implications to establish proper treatment and, therefore, its tremendous effect on patients. Early diagnosis and treatment can turn these patients' lives upside down. The aim of this review is to focus on the clinical guidance, differential diagnosis, and management strategies. In addition, other aspects of lipoedema, including epidemiology and pathogenesis, are also being discussed here. Lipoedema is distinct from obesity and distinct from lymphoedema, although it might progress to involve the venous and lymphatic system (venolipedema or lympholipedema or both). Late diagnosis can leave the patient debilitated. Management of lipoedema includes weight loss, control of oedema, complex decongestive physiotherapy, liposuction, and laser-assisted lipolysis. However; there are increasing reports on tumescent liposuction as the preferred surgical option with long-lasting results. The role of more randomised controlled studies to further explore the management of this clinical entity remains promising.

Abstract
BACKGROUND Patients increasingly seek to enhance the appearance of their legs. Elimination of unwanted leg veins, reduction of epidermal photo-aging changes such as solar lentigines and keratoses, tightening of skin laxity and reduction of adipose tissue are among the most commonly requested goals. Many patients require a combination approach to address their concerns. It is important for dermatologists to be aware of the multitude of procedures that can be performed, often in combination, to rejuvenate the leg. OBJECTIVE The purpose of this review article was to discuss procedures for improving the appearance of the leg and to share the authors experience, especially in the combination approach to leg rejuvenation. METHODS A literature search was performed to investigate cosmetic procedures being performed on the leg, with an emphasis on controlled or randomized studies. In addition, the authors contributed their personal experience. RESULTS Our discussion of the literature review highlights the treatments for leg veins, unwanted fat, cellulite, and photodamage of the legs that are most supported in peer-reviewed publications. CONCLUSION A synergistic, combination approach to leg rejuvenation works best. This includes the use of injectable agents, energy-based devices, and more invasive surgical procedures.

Abstract
Background Upper arm deformities secondary to weight loss or senile elastosis have led to an increased demand for aesthetic contouring procedures. Objective To objectively assess whether, in Teimourian high-grade upper arm remodelling, laser-assisted lypolysis (LAL) alone could result in patient satisfaction. Methods Between 2012 and 2013, 22 patients were treated for excessive upper arm fat (Teimourian grade III and IV) solely with LAL. The laser used in the present study was a 1470 nm diode laser (Alma Lasers, Israel) with the following parameters: continuous mode, 15 W power and transmission through a 600 μm optical fibre. Previous mathematical modelling suggested that 0.1 kJ was required to destroy 1 mL of fat. Patients were asked to complete a satisfaction questionnaire. The arm circumference was measured pre- and postoperatively. Treatment parameters, adverse effects and outcomes were recorded. Results Pain during the anesthesia and discomfort after the procedure were minimal. Complications included ecchymoses and prolonged edema. The mean (± SD) arm circumference decreased 5.5±1.0 cm in the right arm (P<0.01) and 5.2±1.1 cm in the left arm (P<0.01) in grade III patients and 4.9±1.1 cm in the right arm (P<0.01) and 4.9±1.1 cm in the left arm (P<0.01) in grade IV patients. Although the circumference of both arms significantly decreased in grade III and grade IV patients, the skin tightening remained incomplete. Overall, the average opinion of treatment was poor for both patients and investigators. Of the 22 patients, only nine (41%) would recommend this treatment. Conclusion LAL for upper arm remodelling is not sufficient to ensure full skin tightening for patients with Teimourian grades III and IV upper arm deformities. A complementary surgery is mandatory for grades III and IV.

Abstract
Upper arm deformities secondary to weight loss or senile elastosis have led to an increased demand for aesthetic contouring procedures. We conducted this study to objectively assess if, in Teimourian low-grade upper arm remodelling, one session of laser-assisted lypolisis (LAL) could result in full patient satisfaction. Between 2011 and 2013, 45 patients were treated for unsightly fat arm Teimourian grade I (15 patients), grade IIa (15 patients) and grade IIb (15 patients) with one session of LAL. The laser used in this study was a 1470-nm diode laser (Alma Lasers, Cesarea, Israel) with the following parameters: continuous mode, 15 W power and transmission through a 600-μm optical fibre. Previous mathematical modelling suggested that 0.1 kJ was required in order to destroy 1 ml of fat. Treatment parameters and adverse effects were recorded.The arm circumference and skin pinch measurements were assessed pre and postoperatively. Patients were asked to file a satisfaction questionnaire. Pain during the anaesthesia and discomfort after the procedure were minimal. Complications included prolonged oedema in 11 patients. The average arm circumference decreased by 4.9 ± 0.4 cm in the right arm (p < 0.01) and 4.7 ± 0.5 cm in the left arm (p < 0.01) in grade I patients, 5.5 ± 0.6 cm in the right arm (p < 0.01) and 5.2 ± 0.5 cm in the left arm (p < 0.01) in grade IIa patients and 5.4 ± 0.5 cm in the right arm (p < 0.01) and 5.3 ± 0.5 cm in the left arm (p < 0.01) in grade IIB patients. The skin tightening effect was confirmed by the reduction of the skin calliper measurements in all three groups. Overall mean opinion of treatment was high for both patients and investigators. Of the 45 patients, all but one would recommend this treatment. A single session of LAL in upper arm remodelling for Teimourian grades I to IIb is a safe and reproducible technique. The procedure allows reduction in the amount of adipose deposits while providing full skin tightening.

Abstract
Lipedema is a disorder of adipose tissue that primarily affects females and is often misdiagnosed as obesity or lymphedema. Relatively few studies have defined the precise pathogenesis, epidemiology, and management strategies for this disorder, yet the need to successfully identify this disorder as a unique entity has important implications for proper treatment. In this review, we sought to review and identify information in the existing literature with respect to the epidemiology, pathogenesis, clinical presentation, differential diagnosis, and management strategies for lipedema. The current literature suggests that lipedema appears to be a clinical entity thought to be related to both genetic factors and fat distribution. While distinct from lymphedema and obesity, there are some existing treatments such as complex decongestive physiotherapy, liposuction, and laser-assisted lipolysis. Management of lipedema is complex and distinct from lymphedema. The role of newer randomized controlled studies to further explore the management of this clinical entity remains promising.
