Simultaneous Zygomatic Osteotomies With Reduction Mandibuloplasty - An Approach to Mid- and Lower-Facial Feminization in the Transfeminine Patient.

BACKGROUND: Facial feminization surgery (FFS) is effective at treating gender dysphoria associated with anthropometrically masculine facial features. For many transgender women, FFS is a crucial component of the gender transition process. The purpose of this study is to report our experience with a pragmatic technique for simultaneous mid- and lower-face feminization by zygomatic osteotomy malarplasty and reduction mandibuloplasty. METHODS: The technique to perform zygomatic osteotomy malarplasty and reduction mandibuloplasty is described, utilizing harvested bone from the mandible for bone grafting the zygomatic osteotomy gap. A retrospective chart review was performed for patients who underwent simultaneous middle and lower FFS using the described technique. Independent reviewers evaluated cropped preoperative and postoperative photographs of the mid and lower face and assigned each photograph a "femininity score." RESULTS: Seventeen transgender women underwent simultaneous zygomatic osteotomy malarplasty and reduction mandibuloplasty over the study period with adequate follow-up (average 11.1 months). Transient nerve weaknesses were the primary complications noted. A statistically significant improvement in femininity score was reported in postoperative photographs, compared to preoperative photographs ( P < 0.01). CONCLUSIONS: The technique described in this study is an effective application of craniofacial approaches and techniques for feminizing the facial skeleton in transgender women by utilizing harvested mandibular bone for simultaneous malarplasty.

Patient-reported Outcome Measures following Traumatic Lower Extremity Amputation: A Systematic Review and Meta-analysis.

BACKGROUND: Outcomes after traumatic major lower extremity amputation (MLEA) have focused on surgical complications, despite the life-altering impact on patients. With advances in the surgical management of MLEA, a heightened need for consistent reporting of patient-centered outcomes (PCO) remains. This meta-analysis assesses articles for the prevalence and methods of PCO reporting among traumatic MLEA studies. METHODS: An electronic database search was completed using Ovid MEDLINE for studies published between 2000 and 2020. Studies were included that reported any outcome of traumatic MLEA. Weighted means of outcomes were calculated when data were available. The prevalence of PCO was assessed in the categories of physical function, quality of life (QOL), psychosocial, and pain. Trends in PCO reporting were analyzed using Pearson's chi-squared test and analysis of variance when appropriate. RESULTS: In total, 7001 studies were screened, yielding 156 articles for inclusion. PCO were evaluated in 94 (60.3%) studies; 83 (53.2%) reported physical function and mobility outcomes, 33 (21.2%) reported QOL and satisfaction measures, 38 (24.4%) reported psychosocial data, and 43 (27.6%) reported pain outcomes. There was no change in prevalence of PCO reporting when comparing 5-year intervals between 2000 and 2020 (P = 0.557). CONCLUSIONS: Optimization of function and QOL following traumatic MLEA has become a cornerstone of surgical success; however, only 60% of studies report PCO, with no trend over the last two decades suggesting improvement. As healthcare progresses toward patient-centered care, this inconsistent means of reporting PCO calls for improved inclusion and standardization of instruments to assess function, QOL, and other patient-focused measures.

Masculinized Male Chest Contouring: Creating the Armor Plate.

Male patients are routinely consulted regarding dislike of their chest appearance. To date, majority of patients have desired elimination of their feminine-appearing breast, termed gynecomastia. These patients have associated their overweight body image, with the femininity of their breasts as presented by fullness and roundedness of their breasts and subsequently have desired maximal flattening of their breast. We present a new set of patients who desire a more muscular-appearing chest than a gynecomastia repair that is interposed on a chiseled abdominal contour. In contrast to the former set of patients, these patients desire bulking of their breasts with a bolder-appearing armor plate look. We present an alternative to traditional gynecomastia repair which involves a novel approach to chest contouring creating a flat, yet bold, pentagonal-shaped breast with linear borders utilizing both fat and gland removal as well as strategic fat grafting back into the chest. We present a novel protocol to create an armor plate male chest appearance as an alternative to traditional gynecomastia contouring. All patients treated to date demonstrate a muscular-appearing chest that is harmonious on an interposed masculine-appearing abdomen.

Successful Back Contouring With Elimination of Back Rolls Using Ultrasound-Assisted Liposuction and Helium-Activated Radiofrequency.

BACKGROUND: Patients are routinely consulted regarding dislike of their upper and middle back contour and associated back rolls that stick out of their bras. Although patients only associate this fullness with excess fat, on examination it becomes evident that back rolls are due to a combination of excess fat as well as skin redundancy. To date, treatment of both excess skin and fat in back rolls has required consideration of excisional surgery such as an upper body lift. OBJECTIVES: We present 14 consecutive back contouring cases that were treated with an alternative protocol involving simultaneous ultrasound assisted liposuction and helium activated radiofrequency. METHODS: Patients underwent ultrasound assisted liposuction to remove superficial fat over the upper and middle back as well as helium activated radiofrequency to tighten the skin using subdermal coagulation. RESULTS: All 14 patients visually demonstrated elimination of back rolls and improvement in upper and middle back contour. All 14 patients also reported overall satisfaction in their postoperative follow-ups at 3, 6, and 12-months. CONCLUSION: In summary, simultaneous ultrasound assisted liposuction and helium activated radiofrequency provide an effective treatment for patients desiring improvements in upper and middle back contour and elimination of back rolls while avoiding more invasive excisional surgeries.

Atomistic aspects of ductile responses of cubic silicon carbide during nanometric cutting.

Cubic silicon carbide (SiC) is an extremely hard and brittle material having unique blend of material properties which makes it suitable candidate for microelectromechanical systems and nanoelectromechanical systems applications. Although, SiC can be machined in ductile regime at nanoscale through single-point diamond turning process, the root cause of the ductile response of SiC has not been understood yet which impedes significant exploitation of this ceramic material. In this paper, molecular dynamics simulation has been carried out to investigate the atomistic aspects of ductile response of SiC during nanometric cutting process. Simulation results show that cubic SiC undergoes sp3-sp2 order-disorder transition resulting in the formation of SiC-graphene-like substance with a growth rate dependent on the cutting conditions. The disorder transition of SiC causes the ductile response during its nanometric cutting operations. It was further found out that the continuous abrasive action between the diamond tool and SiC causes simultaneous sp3-sp2 order-disorder transition of diamond tool which results in graphitization of diamond and consequent tool wear.
