Background: Hemoglobin A 1c (HbA 1c ) and body mass index (BMI) are routinely evaluated before both alloplastic and autologous breast reconstruction to assess postoperative complication risk. However, evidence-based guidelines regarding accepted cutoffs for these measures are limited. This study aimed to elucidate the associations between HbA 1c levels or BMI with wound complications following reconstructive breast surgery.

Autologous vascular grafts, the only clinically approved option for small-diameter (<6 mm) revascularizations, require invasive harvesting and have limited availability and variable quality. To address these challenges, we develop a 3-mm-diameter artery graft by using arterial endothelial cells (AECs) derived from pluripotent stem cells (PSCs). After establishing technologies for pure AEC generation and expanded polytetrafluoroethylene (ePTFE) graft coating, we engineer artery grafts by seeding the inner lumen of ePTFE vascular grafts with either major histocompatibility complex (MHC) mismatched unmodified-wild-type (MHC-WT) AECs or MHC class I/II double knockout (MHC-DKO) AECs.

Introduction: Adult-acquired buried penis (AABP) is an increasingly prevalent condition characterized by the penis "buried" in prepubic/suprapubic tissue. AABP affects urinary and sexual function, hygiene, and psychosocial well-being. Because many affected individuals are unfamiliar with the condition or hesitant to seek medical help, accessible, high-quality patient education materials (PEMs) are necessary.

Objectives: To investigate the consistency of associations between modified frailty index-5 (mFI-5) and postoperative adverse outcomes in head and neck cancer (HNC) reconstruction.

Methods: American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database from 2017 to 2022 was utilized to identify HNC patients undergoing locoregional or microvascular free tissue transfers. Kaplan-Meier estimates and multivariable Cox regression analyses were utilized to compare risk of infections, bleeding, readmissions, reoperations, major adverse cardiovascular events (MACE), and mortality within the first postoperative month for each mFI-5 score with mFI-5 = 0 as reference.

Background:  High levels of precision, as well as controlled, efficient motions, are important components of microsurgical technique and success. An accurate and objective means of skill assessment is lacking in resident microsurgical education. Here we employ three-dimensional, real-time motion-tracking technology to analyze hand and instrument motion during microsurgical anastomoses.

Autologous breast reconstruction remains a popular surgical option following mastectomy; however, it is not without complications. Preoperative CT angiograms (CTAs) are often obtained for surgical planning, and morphometric data such as fat and muscle distribution can be measured. This study aimed to assess if CTA morphometric data predicts abdominal donor site complications in patients undergoing abdominally based autologous breast reconstruction.

Drain placement is commonplace after many plastic surgery procedures to evacuate excess blood and fluid. Tranexamic acid (TXA) is an antifibrinolytic that has been shown to decrease bleeding and fluid production at surgical sites and can be administered orally, intravenously, and topically. The purpose of this study is to evaluate the effect of topical TXA on drain removal in abdominally based autologous breast reconstruction (ABABR).

Background: Plastic and reconstructive surgery is one of the most competitive residency programs, and given the increased number of applicants for a relatively fixed number of positions, successfully matching is a challenge. Match rates have declined since 2018, with a match rate of ~55% in 2022. Two common options before reapplying are a preliminary year of residency (preliminary year) or a research fellowship.

Keloids represent a symptomatic, aberrant healing process that is difficult to treat with high recurrence rates spanning from 55% to 100% if treated excision without adjuvant therapy. Electrical stimulation (ES) has demonstrated findings that suggest it could reduce the recurrence rate of keloids after resection. Therefore, the aim of this study is to conduct a scoping review to investigate ES as an adjuvant therapy for decreasing keloid recurrence after excision.

Background:  Decreased autologous flap vascular perfusion can lead to secondary procedures. Fluorescence angiography during surgery reduces the probability of repeat surgery but suffers from interpretation variability. Recently, the OnLume Avata System was developed, which evaluates real-time vascular perfusion in ambient light.

Microsurgery is a complex subspecialty requiring fine manual dexterity and a thorough understanding of microsurgical techniques, requiring years of training to reach proficiency. On a global scale, trainees may not have access to a longitudinal microsurgery curriculum and instead attend brief courses to learn microsurgical techniques, limiting their ability to practice the nuances of microsurgery. There remains a gap in global microsurgical education for trainees to have consistent educational exposure.

Nipple-areolar complex (NAC) necrosis is a devastating complication in nipple-sparing mastectomies (NSMs) that significantly impacts patient's quality of life. The use of fluorescence angiography for intraoperative assessment of mastectomy skin flap perfusion in NSM has been successfully described and can be utilized to help guide surgical decision-making. Recently, a novel fluorescence-guided surgical imager was developed, OnLume Avata System (OnLume Surgical, Madison, WI), which provides intraoperative evaluation of vascular perfusion in ambient light.

Purpose: Adult acquired buried penis (AABP) is a morbid condition often necessitating surgical intervention. Accurate assessment of pre- and postoperative symptoms is crucial to understand how AABP impacts a patients' quality of life, verify surgical effectiveness, and practice patient-centered care. There is no validated patient-reported outcome instrument specific for AABP evaluation.

Background:  Perforator dissection and flap elevation are routinely performed for microsurgical reconstruction; however, there is a steep learning curve to mastering these technical skills. Though live porcine models have been utilized as microsurgical training models, significant drawbacks limit their use. We recently developed a latex-perfused, nonliving, porcine abdomen perforator dissection simulation and described its anatomic similarity to the human deep inferior epigastric artery flap.

Breast reconstruction is highly complex, requiring navigation of not only clinical and operative realities, but of patient expectations as well. The authors sought to identify historical art pieces that exhibit breast asymmetries and deformities for comparison with photographs of breast reconstruction patients seen at the clinic of the senior author (S.O.

Background: Given that patients with morbid obesity are predisposed to frailty, we sought to determine whether the 5-Factor Modified Frailty Index (mFI-5) predicts postoperative complications following surgery for adult-acquired buried penis, and secondarily, to compare the mFI-5 to body mass index (BMI) and American Society of Anesthesiologists (ASA) status as preoperative risk stratification measures.

Methods: We included all patients who underwent surgical management for adult-acquired buried penis at an academic Level I trauma center between 2015 and 2023. A manual chart review was performed to collect data on patient demographics, modified frailty index variables, intraoperative data, postoperative outcomes, and complications.

Background: The hypothesis of this study was that trigeminal nerve stimulation (TNS) or peripheral nerve stimulation (PNS) could improve functional outcomes of peripheral nerve injury in a rat forelimb model when compared to control rats not receiving electrical stimulation (ES). While PNS is known to improve outcomes after nerve surgery, the role of TNS has not been explored.

Methods: Lewis rats were trained to perform a reach and grasp task before receiving a 2 mm gap repair of the ulnar and median nerves and randomized into four treatment groups: (1) sham injury, (2) nerve injury with sham ES, (3) nerve injury with PNS, and (4) nerve injury with TNS.

Career-related injuries and disorders in professional musicians are prevalent across all their respective instruments and fields. They often endure long hours of intensive practice that demand high levels of precision, dexterity, and flexibility of their head, neck, hands, and upper extremities. Unlike the average patient, musicians are sensitive to even mild symptoms and deficits that can interfere with performance, which can potentially be career-threatening.
