Skin expansion delivers newly grown skin that maintains histological and mechanical features of the original tissue. Although it is the gold standard for cutaneous defect correction today, the underlying mechanisms remain poorly understood. Here we present a novel technique to quantify anisotropic prestrain, deformation, and growth in a porcine skin(More)
BACKGROUND Growing numbers of men are presenting for consultation and potential postbariatric body contouring surgery. Due to concerns about whether men might have increased rates of complications or dissatisfaction with aesthetic surgery, the authors assessed their clinical experience with male patients. METHODS The authors examined male patients in(More)
BACKGROUND Esophageal injury following anterior cervical discectomy and fusion (ACDF) poses a significant reconstructive challenge. Buttressing flap repairs have proven beneficial; however, there remains a paucity of evidence to guide optimal flap selection. METHODS A retrospective chart review was performed for patients who presented to the senior author(More)
This study explored the perceptions of women after receiving breast biopsy results over the phone in order to determine patient preferences about the timing, setting, and provider they preferred when receiving biopsy results. Participants were recruited at a large university cancer center and surveyed by phone approximately 2 weeks after they received(More)
Skin expansion is a common surgical technique to correct large cutaneous defects. Selecting a successful expansion protocol is solely based on the experience and personal preference of the operating surgeon. Skin expansion could be improved by predictive computational simulations. Towards this goal, we model skin expansion using the continuum framework of(More)
BACKGROUND Postbariatric body contouring represents a rapidly growing field. With long operative times and high rates of minor complications, evidence-based guidelines for operative management are needed. Data analyzing the impact of perioperative factors on patient outcomes are currently limited. METHODS Patients who lost 50 pounds or more and underwent(More)
BACKGROUND Although there is a high incidence of flank defects after lateral abdominal access, there is a paucity of large studies discussing this problem. Most studies express nihilism regarding their surgical management. The goal of this study was to describe the authors' conceptualization of flank defects, with a determination of the number of true(More)
BACKGROUND The deep inferior epigastric perforator (DIEP) flap has gained notoriety because of its proposed benefit in decreasing donor-site morbidity but has been associated with longer operative times, higher perfusion-related complications, and increased cost relative to muscle-sparing free transverse rectus abdominis myocutaneous (TRAM) flaps. The(More)
BACKGROUND Unlike traditional plastic surgery patients who present with a specific anatomical complaint, massive weight loss patients often have multiple regions of concern. No single procedure can address the whole-body deformities associated with massive weight loss. The authors sought to quantify their clinical experience to provide evidence-based(More)
INTRODUCTION Since the initiation of the "Back to Sleep Campaign" by the American Academy of Pediatrics in 1992, the incidence of referrals for positional plagiocephaly has increased by 600%. Although patients with positional plagiocephaly rarely require operative intervention, they often do require treatment with cranial molding helmets or positioning(More)
