Purpose: Use of video-based education (VBE) to teach surgical skills has increased rapidly and been shown to accelerate students' and residents' time to satisfactory skill acquisition while also improving trainees' satisfaction. However, its implementation is limited by logistical factors such as: video quality, view obstruction, and excessive motion. We aim to study the feasibility of using VBE to teach medical students basic suturing skills.

Purpose: The use of "mesh" in implant-based reconstruction is widespread, with both acellular dermal matrices (ADMs) and extracellular matrices (ECMs) being used, especially in prepectoral device placement. This study compared Ovitex (ovine ECM) versus human cadaveric ADMs to determine safety profiles and cost-effectiveness.

Methods: A single surgeon's longitudinal experience with 2-stage, immediate tissue expander breast reconstruction from 2018 to 2023 was analyzed.

Background And Objective: While significant sensation recovery improvements in neurotized breasts following reconstruction have been reported, sensation testing methods and surgical techniques have been widely variable. This narrative review aims to summarize available literature on current neurotization practices and sensory recovery outcomes in patients undergoing innervated breast reconstruction.

Methods: A comprehensive literature search of PubMed Medline, Web of Science, and Embase was conducted to identify all studies reporting outcomes of neurotization in breast reconstruction surgeries.

Facial palsy is a condition that affects the facial nerve, the seventh of the 12 cranial nerves. Its main function is to control the muscles of facial expression. This involves the ability to express emotion through controlling the position of the mouth, the eyebrow, nostrils, and eye closure.

Background: The importance of adaptable and up-to-date plastic surgery graduate medical education (GME) has taken on new meaning amidst accelerating surgical innovation and increasing calls for competency-based training standards. We aimed to examine the extent to which the procedures plastic surgery residents perform, as represented in case log data, align with 2 core standardized components of plastic surgery GME: ACGME (Accreditation Council for Graduate Medical Education) minimum procedure count requirements and the PSITE (Plastic Surgery In-Service Training Examination). We also examined their alignment with procedural representation at 2 major plastic surgery meetings.

Background: The use of left ventricular assist devices (LVADs) for patients with end-stage cardiac failure awaiting heart transplantation has become increasingly common. However, ventricular assist device-related infections remain a major problem complicating their long-term use. Retrospective review has previously shown a decrease in lifetime return to operating room (RTOR) with no change in 90-day complications when a muscle or omental flap is used for coverage after washout for infection.

Introduction: Both biologic and permanent (synthetic) meshes are used for abdominal wall reconstruction. Biologic mesh has the advantage of eventual incorporation, which makes it generally preferred in contaminated patients compared with synthetic mesh (Ann Surg. 2013;257:991-996).

Background: Pharyngeal flap (PF) surgery is effective at improving velopharyngeal sufficiency, but historical literature shows a concerning prevalence rate of obstructive sleep apnea (OSA), reported as high as 20%. Our institution has developed a protocol to minimize risk of postoperative obstructive complications and increase safety of PF surgery. We hypothesize that (1) preoperative staged removal of significant adenotonsillar tissue along with (2) multiview videofluoroscopy to guide patient-specific surgical approach via appropriately sized PFs can result in excellent speech outcomes while limiting occurrence of OSA.

In Eastern nations, interventions like acupuncture and herbal medicine are often first-line for patients presenting with facial paralysis. Despite the rising popularity of Eastern medicine in Western nations, the literature assessing whether Eastern medicine interventions should be recommended for patients with facial paralysis is lacking. This meta-analysis aims to define what Eastern medicine interventions exist for the management of facial paralysis and assess whether current research supports these approaches as safe and effective.

While racial, ethnic, and socioeconomic disparities in burn care have been identified in the literature, there is a paucity of research into specific underlying causes of these disparities. Here, we sought to characterize whether time to initial burn consult might contribute to racial, ethnic, and socioeconomic differences in burn care outcomes. We performed a retrospective review of all patients evaluated by the burn surgery service at a single regional ABA-verified burn center between June 2020 and April 2022.

Objective: To determine whether performing tonsillectomy at the time of Furlow palatoplasty for the treatment of cleft palate related velopharyngeal insufficiency (VPI) incurs increased surgical complications or compromises speech outcomes.

Design: A retrospective review of patients who had Furlow palatoplasty and the outcomes of surgery in the treatment of cleft palate related VPI.

Setting: A single academic center between January 2015 and January 2022.

Background: The use of left ventricular assist devices (LVADs) for patients with end-stage cardiac failure awaiting heart transplantation has become increasingly common. However, ventricular assist device-related infections remain a major problem complicating their long-term use. Poor data exist to determine how to manage these infections after operative debridement.

Background: Approximately 80% of patients undergoing total mastectomy in the US opt for implant-based breast reconstruction (IBBR). A two-stage reconstruction with tissue expander (TE) remains the most common technique. Since the implementation of ADMs, a prepectoral approach has gained popularity and is becoming the standard of care.

Negative-pressure wound therapy (NPWT) over split thickness skin grafts can control exudate, decrease infection rates, and improve revascularization. However, no study specifically addresses differences in outcomes between meshed/perforated and non-meshed autologous skin grafts dressed with NPWT. Through retrospective chart review, patients undergoing autologous split thickness skin grafting with a NPWT dressing for any burn injury over a 10-month period were identified.

Background: Because of the recent attention focused on the aesthetics of the leg, outcomes in the literature are under-reported and require further investigation. We summarized the available evidence on the surgical techniques to augment the volume and dimension of the calf based on clinical outcomes and satisfaction rates.

Methods: An electronic search was conducted across PubMed MEDLINE, Web of Science, Scopus, and Ovid MEDLINER(R) in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement.

Merkel cell carcinoma (MCC) is a rare and highly aggressive skin cancer which most commonly occurs on the head and neck. A limited number of cases of MCC of the hand have been reported in the English literature. We describe a case of MCC of the hand in a man in his late 60s.

Unlabelled: Acellular dermal matrices (ADMs) are used for soft tissue augmentation across surgical specialties. Since allograft incorporation depends on direct opposition between the ADM and a vascular bed, seroma formation can be detrimental to incorporation. Since most ADM products are available in many meshed and perforated forms, there is a lack of consistency between manufacture designs.
