Surgical Excision of Burn Wounds.

Burn injuries affect patients of all ages, and timely surgical debridement and excision commence to protect dermal vascularity and integrity, improve healing, and minimize scarring. Several tools may be used for burn wound excision, which is performed either tangentially or down to muscular fascia. Once wounds are optimized from a tissue viability and healing standpoint, coverage may be obtained through grafts or secondary intention healing for more superficial injuries.

Tissue Expanders in Staged Calvarial Reconstruction: A Systematic Review.

Cranioplasties are common procedures in plastic surgery. The use of tissue expansion (TE) in staged cranioplasties is less common. We present two cases of cranioplasties with TE and systematically review literature describing the use of TE in staged cranioplasties and postoperative outcomes.

Silicone Breast Implant Surface Texture Impacts Gene Expression in Periprosthetic Fibrous Capsules.

Background: Silicone breast implants with smooth outer shells are associated with higher rates of capsular contracture, whereas textured implants have been linked to the development of breast implant-associated anaplastic large cell lymphoma. By assessing the gene expression profile of fibrous capsules formed in response to smooth and textured implants, insight into the development of breast implant-associated abnormalities can be gained.

Methods: Miniature smooth or textured silicone implants were surgically inserted into female rats ( n = 10) and harvested for the surrounding capsules at postoperative week 6.

Urinary Bladder Matrix Improves Irradiated Wound Healing in a Murine Model.

Radiation skin damage is associated with chronic wounds and poor healing. Existing localized treatment modalities have limited benefit. Therefore, there has been increased interest in biologically based solutions.

Patents for the Plastic Surgeon: A Primer.

Although innovation and entrepreneurship are complementary in the process of creating new products, plastic surgeons are frequently discouraged by the challenges associated with the regulatory and administrative environments in patent filing. The following primer provides a step-by-step guide for understanding patents and outlines the steps and costs involved in patent filing. To improve opportunities for successful patent filing, we elaborate on some of the common pitfalls in the process, including the timing of public disclosure, conducting a private art search, selecting a patent attorney or agent, determining the level of inventor involvement, and navigating academic and employment contracts.

Use of Single Chimeric Free Flaps or Double Free Flaps for Complex Head and Neck Reconstruction.

Background:  Free flaps have become the preferred reconstructive approach to restore form and function for patients presenting with complex head and neck defects. For composite, complex defects for which a regular free flap might not meet all reconstructive demands, adequate coverage can be achieved with either a single chimeric free flap or a double free flap.

Methods:  We performed a single-center retrospective chart review of patients who underwent either single chimeric free flap or double free flap reconstruction.

The Evolution of Unilateral Cleft Lip Repair.

The understanding of cleft lip etiology and approaches for surgical repair have evolved over time, allowing for improved ability to restore form and function. The variability of cleft lip presentations has necessitated a nuanced surgical approach with multidisciplinary cleft care. The earliest documentation of unilateral cleft lip repair predates the 19th century, with crude outcomes observed before the advent of curved incisions and advancement flaps.

Prognostic Role of Programmed Cell Death 1 Ligand 1 in Resectable Pleural Mesothelioma.

Background: The prognostic role of programmed cell death 1 ligand 1 (PD-L1) in malignant pleural mesothelioma (MPM) is incompletely understood. Our objectives were to evaluate the evidence for tumor PD-L1 as a prognostic biomarker in MPM through meta-analysis and to determine whether tumor PD-L1 expression is associated with survival in MPM patients undergoing macroscopic complete resection.

Methods: Meta-analysis was performed to determine the association of PD-L1 with overall survival in MPM (n = 1655) from 14 studies containing overall survival and tumor PD-L1 expression.

Craniofacial phenotypes associated with Robinow syndrome.

Robinow syndrome is characterized by mesomelic limb shortening, hemivertebrae, and genital hypoplasia. Due to low prevalence and considerable phenotypic variability, it has been challenging to definitively characterize features of Robinow syndrome. While craniofacial abnormalities associated with Robinow syndrome have been broadly described, there is a lack of detailed descriptions of genotype-specific phenotypic craniofacial features.

The Addition of Partial or Circumferential Liposuction to Abdominoplasty Is Not Associated With a Higher Risk of Skin Necrosis.

Background: Combining abdominoplasty with liposuction is a common practice for optimal patient aesthetic outcomes. In the past, several practitioners have argued against liposuction due to the potential for vascular insufficiency, especially with central liposuction. Despite these concerns for flap damage with resultant necrosis, the incidence of this complication has not been comprehensively investigated.

Role of stem cell therapies in treating chronic wounds: A systematic review.

Background: The impairment of cutaneous wound healing results in chronic, non-healing wounds that are caused by altered wound environment oxygenation, tissue injury, and permissive microbial growth. Current modalities for the treatment of these wounds inadequately address the complex changes involved in chronic wound pathogenesis. Consequently, stem cell therapies have emerged as a potential therapeutic modality to promote cutaneous regeneration through trophic and paracrine activity.

Preoperative prediction of unresectability in malignant pleural mesothelioma.

Objective: Diffuse chest wall invasion (DCWI) is a common finding in patients undergoing intended resection for malignant pleural mesothelioma. We sought to determine the incidence and preoperative predictors of this finding, and to test our anecdotal impression that contraction of the ipsilateral hemithorax is associated with DCWI.

Methods: This was a single-institution retrospective study of 170 patients undergoing intended macroscopic complete resection for malignant pleural mesothelioma from 2014-2018.

Vascularized Iliac Bone Graft for Complex Closure During Spinal Deformity Surgery.

Spinal pseudarthrosis is failure of bony union across a segment where arthrodesis has been attempted. A variety of treatment approaches have been proposed to promote bony union, including use of vascularized bone graft. We report a successful application of vascularized pedicled iliac crest bone graft (ICBG) to treat recurrent lumbar and sacral pseudarthrosis.

Confusion Instead of Clarity: Publicly Reported Cardiac Surgery Ratings for Coronary Artery Bypass Grafting and Aortic Valve Replacement.

Background: Public reporting of cardiac surgery ratings has been advocated to inform patient selection of hospitals. Although Society of Thoracic Surgeons (STS) ratings are based on audited risk-adjusted patient outcomes, other rating systems rely on administrative databases. In this study, we evaluate correlation among 4 widely used hospital rating systems for coronary artery bypass grafting (CABG) and aortic valve replacement (AVR).
