Long-term Outcomes After Gender-Affirming Surgery: 40-Year Follow-up Study.

Background: Gender dysphoria is a condition that often leads to significant patient morbidity and mortality. Although gender-affirming surgery (GAS) has been offered for more than half a century with clear significant short-term improvement in patient well-being, few studies have evaluated the long-term durability of these outcomes.

Methods: Chart review identified 97 patients who were seen for gender dysphoria at a tertiary care center from 1970 to 1990 with comprehensive preoperative evaluations.

Quantifying Burn Injury-Related Disability and Quality of Life in the Developing World: A Primer for Patient-Centered Resource Allocation.

Background: Untreated or undertreated burns are commonly encountered by plastic surgeons on medical trips in India and represent a major cause of disability. We sought to utilize validated patient-reported outcomes instruments to identify the patient population with the greatest burn-related disability in order to appropriately allocate plastic surgery resources to those in greatest need.

Methods: The Quick Disability of the Arm, Shoulder, and Hand, RAND 36-Item Short Form Health Survey, and Burn-Specific Health Scale-Revised, Brief, and Adapted questionnaires were administered via an interpreter during a plastic surgery trip to Jharkhand, India, in January 2018.

Paradoxical Adipose Hyperplasia and Cellular Effects After Cryolipolysis: A Case Report.

Cryolipolysis is a noninvasive technique for the reduction of subcutaneous adipose tissue by controlled, localized cooling, causing adipocyte apoptosis, reportedly without affecting surrounding tissue. Although cryolipolysis has a low incidence of adverse side effects 33 cases of paradoxical adipose hyperplasia (PAH) have been reported and the precise pathogenesis of PAH is poorly understood. This present case study of PAH aims to characterize the pathological changes in the adipose tissue of PAH on a cellular level by using multiple different assays [hematoxy lin and eosin staining, LIVE/DEAD staining, BODIPY(®) 558/568 C12 (4,4-Difluoro-5-(2-Thienyl)-4-Bora-3a,4a-Diaza-s-Indacene-3-dodecanoic acid) staining].

Resident Participation in International Surgical Missions is Predictive of Future Volunteerism in Practice.

Background: Interest in global health and international mission trips among medical student and resident trainees is growing rapidly. How these electives and international mission experiences affect future practice is still being elucidated. No study has identified if participation in international surgical missions during residency is a predictor of participation in international surgical missions in practice after training completion.

The Average Size and Position of the Umbilicus in Young Men and Women.

Introduction: Abdominoplasty was the third most common cosmetic surgical procedure in 2012. The umbilicus is transposed within the abdominal skin flap during this procedure. Few studies address the size and location of the umbilicus with precise measurements as well as those that do report on a heterogeneous population.

Transverse mucoperiosteal flap inset by rotation for cleft palate repair: technique and outcomes.

Introduction: Cleft palate is a relatively common deformity with various techniques described for its repair. Most techniques address the hard palate portion of the cleft with bilateral mucoperiosteal flaps transposed to the midline. This results in superimposed, linear closure layers directly over the cleft and may predispose the repair to oronasal fistula formation.

Treatment of postsurgical temporal hollowing with high-density porous polyethylene.

Temporal hollowing is most frequently an acquired defect and can be caused by a volumetric deficiency of bone, soft tissue, or both. Given high-density porous polyethylene's ease of use, customizability, long-term strength and resiliency, and successful application in other areas of the craniofacial skeleton, the authors have used it as the first-line material for reconstruction of temporal hollowing. Herein, we present 4 illustrative cases demonstrating this technique and further describe subtypes of the temporal defect with appropriate means of reconstruction.

The use of an acellular dermal matrix "sandwich" for the successful treatment of a persistent cranial cerebrospinal fluid fistula.

Cerebrospinal fluid (CSF) fistulae are problematic because of the high risk of meningitis and other infectious complications, as well as the potential for critically delaying chemotherapy in cases associated with malignancy. The plastic surgical literature suggests vascularized autologous tissue for the treatment of chronically draining CSF fistulae. Many of these patients, however, are debilitated, have multiple comorbidities, and may have a limited life expectancy, making the lengthy surgery and the associated donor-site morbidity of a regional or free tissue transfer procedure unattractive.

Burn management in sub-Saharan Africa: opportunities for implementation of dedicated training and development of specialty centers.

Background: In low- and middle-income countries burn injuries remain responsible for a large burden of death and disability. Given an annual worldwide incidence of almost 11 million new individuals affected per year, major burn injuries have a higher annual incidence than HIV and tuberculosis combined.

Methods: A survey instrument was adapted for use as an international assessment tool and then used to measure the availability of personnel, materials, equipment, medicines, and facility resources in nine Rwandan hospitals, including three referral centers.

Special considerations in the management of pediatric upper extremity and hand burns.

Pediatric patients account for approximately one third of all burn patients in the United States, with upper extremity or hand involvement in most admitted burn patients. Specialized management and care of pediatric burn patients optimizes functional outcomes. Common mechanisms of injury are discussed.

Silicone gel implants in breast augmentation and reconstruction.

Silicone gel implants have been widely used for breast augmentation and reconstruction since the 1960s. Several alterations to both elastomer shell and filler gel have been made over the years to improve their ability to replicate the natural breast and to decrease the incidence of capsular contracture. The latter is a pathologic process involving the periprosthetic tissues formed in response to the presence of the implant.

Obstructive sleep apnea: Part II. Surgical approaches to sleep apnea.

Successful surgical management of obstructive sleep apnea (OSAS) requires a thorough understanding of the pathophysiology and anatomical contributions to this widely variable disease. Early efforts to surgically correct OSAS involved bypassing the upper airway; thus, indirectly improving the symptoms without directly addressing the pathophysiology. Surgical procedures to treat OSAS have evolved over the past several decades as further understanding of the disease continues to be elicited.

Lidocaine metabolism pathophysiology, drug interactions, and surgical implications.

A thorough understanding of the pathophysiology of lidocaine metabolism is an important prerequisite to minimizing the risk of morbidity and mortality associated with lipoplasty. Although the tumescent technique has greatly improved the safety of large-volume lipoplasty through decreased blood loss and reduced anesthetic needs, it has introduced the possibility for lidocaine toxicity. Because lidocaine is metabolized by the cytochrome P450 system, the potential for drug interactions is heightened.

Aberrant bony vasculature associated with activating fibroblast growth factor receptor mutations accompanying Crouzon syndrome.

Fibroblast growth factor receptor mutations are associated with and, in fact, cause most syndromes presenting with craniosynostosis. This knowledge has resulted in a shift in the paradigm of suture fusion causation; it was thought previously that abnormal tensional forces arising in the cranial base caused fusion of the vault sutures, but it is now understood that aberrant intercellular signaling in the developing skull leads to abnormal suture morphogenesis. Although the mutations associated with these syndromes are known and the phenotypic consequences are well documented, the pathway from mutation to phenotype has yet to be elucidated.

The "open-book" variation of component separation for repair of massive midline abdominal wall hernia.

The reconstruction of massive midline abdominal wall defects as a result of intra-abdominal catastrophes has long challenged the reconstructive surgeon. Previously, the lack of autogenous tissue often forced the surgeon to resort to synthetic materials, which may be complicated by adhesions, enterocutaneous fistulas, and infection. The introduction of the "components of anatomic separation" technique by Ramirez et al.

Vascular anomalies: hemangiomas.

Mulliken and Glowacki categorized vascular anomalies as either hemangiomas or malformations, with the former being the most common tumor of infancy. Despite distinct clinical, radiologic, and histologic findings, the two major types of vascular lesions are often confused. This complicates both patient care and interpretation of the medical literature.

Beneficial effect of hyperbaric oxygen on island flaps subjected to secondary venous ischemia.

The potential for hyperbaric oxygen therapy (HBO) to decrease the untoward effects of a secondary ischemic event was studied in the rat superficial epigastric flap model. The secondary venous ischemic flap was created by cross-clamping the vascular pedicles for 2 h. Twenty-four hours later, the flap was reelevated and the venous pedicle was occluded for 5 h.
