Plastic and Reconstructive Surgery

INTRODUCTION: Video-assisted debriefing (VAD) combined with the "advocacy and inquiry" (A&I) technique, is a tool that allows video playback of selected segments of a simulation, thereby assisting the debriefers to structure the session. Currently, however, no consensus exists on how to optimally perform a team debriefing. In our study, we aim to demonstrate and describe the methodology of A&I debriefing in an instructional simulated blast scenario and assess the impact of VAD on residents' technical and non-technical skills (NTS)...

Dynamic lip lines pose a challenge in perioral rejuvenation despite the availability of numerous hyaluronic acid (HA) dermal filler products. In this article, we introduce the Additive Orthodiagonal Rhytidoplasty of the Ergotrid (ADORE), a novel technique for the treatment of severe dynamic lip lines. Based on an objective analysis of treatment outcomes, the ADORE technique demonstrates the ability to confer substantial improvement in lip line severity, with a median reduction in lip line intensity of 79% (average = 70%, St...

BACKGROUND: Heterotopic ossification (HO), a common complication after elbow trauma, causes severe limb disability, Surgical resection is usually performed for post-traumatic elbow HO (PTEHO) to regain mobility. Though it was heavily reported, there has been no long-term (minimum 5-year) follow-up. PATIENTS AND METHODS: 173 patients who underwent PTEHO resection were followed up for minimum 5 years in 4 hospitals between January/2015 and August/2016. Demographics, disease characteristics, preoperative and minimum 5-year assessments were collected...

BACKGROUND: Polyethylene glycol (PEG) can fuse severed closely-apposed axolemmas and restore axonal continuity. We evaluated the effects of PEG-fusion on functional recovery in a rodent forelimb model of peripheral nerve injury. METHODS: The median nerves of male Lewis rats (n=5 per group) were transected and repaired with standard suture repair (SR), SR with PEG (PEG), or SR with PEG and 1% methylene blue (PEG+MB); a sham surgery group was also included. Proximal stimulation produced compound nerve (CAPS) and muscle (CMAPs) action potentials recorded distally...

BACKGROUND: The unstable recipient conditions after fat grafting remains an obstacle for tissue volumization. The interaction between fat grafts and recipient sites is not fully understood. We hypothesize that recipient-derived adipocytes undergo dedifferentiation and migrate into fat grafts in tissue regeneration. METHODS: To observe the participation from recipient fat pad, we established a recipient adipocyte-tracing model where 0.2 ml inguinal fat from ten 8-week-old C57BL/6 mice was grafted to ten tamoxifen-treated AdipoqCre;mT/mG mice...

BACKGROUND: Functional recovery following peripheral nerve injury worsens with increasing time of denervation prior to repair. Denervated muscle undergoes progressive atrophy that limits the extent to which motor end plates can be reinnervated. The aim of this study is to assess nerve injuries reconstructed at different time points, and identify various neural and muscle-based markers to predict functional outcome, including an in-depth look at the neuromuscular junction. MATERIAL AND METHODS: Adult wild type C57BL/6J mice received surgery on the sciatic nerve and were divided into five groups: 1) Nerve cut and repaired, 2) Acute: nerve cut and immediately repaired with 1cm autograft, 3) Subacute: nerve grafted two weeks after injury, 4) Delayed (D): nerve grafted four weeks after injury, 5) Nerve cut and capped...

BACKGROUND: Textured implants were developed with the goal of reducing rates of capsular contracture and preventing implant malposition (eg., malrotation). Recent evidence has questioned whether textured implants are as resistant to malrotation as previously reported. METHODS: Women presenting to a single healthcare system for removal of textured implants were prospectively enrolled in the study from September 2019 to July of 2022. Patients who underwent removal of an anatomic, textured implant in the operating room were included in the study, while those who did not undergo implant removal, or were found to have a smooth implant, or a round, textured implant were excluded...

PURPOSE: Post-operative venous thromboembolism (VTE) is a major source of morbidity and mortality. The use of thromboprophylaxis amongst surgeons is not well studied in autologous breast reconstruction. The purpose of this study was to determine the rate of VTE in breast cancer patients undergoing autologous breast reconstruction and to compare the cost-effectiveness of postoperative chemoprophylactic agents. METHODS: The TriNetX LLC. National Health Research Network database was used to identify patients with breast cancer who underwent autologous breast reconstruction surgery between 2002-2022...

BACKGROUND: Capsular contracture is attributed to an exaggerated fibrosis response within the capsule and is partly associated with bacterial contamination in situ. However, the cellular mechanisms that initiate this response are unclear. METHODS: We developed a mouse model of capsular contracture by repeated injection of 10 μg/ml lipoteichoic acid (LTA). The histological changes in the capsule tissue were measured by hematoxylin-eosin, Masson, and immunohistochemical staining...

INTRODUCTION: Autologous tissue is the only permanent option for breast reconstruction. While abdominal tissue remains popular, considering alternative donor sites ensures comprehensive care tailored to a patient. The thigh has been established as an excellent choice in autologous reconstruction. We present a ten-year experience with 405 profunda artery perforator flaps (PAP flaps). METHODS: An IRB approved ten-year retrospective review of all patients treated with PAP flaps for breast reconstruction was performed...

BACKGROUND: Face transplantation has emerged as a viable solution for reconstructing the most complex facial injuries. Prior work has demonstrated that surgical revisions are necessary to optimize outcomes. The authors' group has updated the previous report of revisions in their cohort, quantified and described which revisions were performed for functional, aesthetic, or mixed indications, and described the rationale, safety, and long-term outcomes of these revisions. METHODS: A retrospective analysis of the authors' ten face transplants was performed from April 2009 to February 2023...

BACKGROUND: This study updates our institutional experience with modified Furlow palatoplasty, evaluating speech outcomes and incidence of secondary speech surgery throughout development and at skeletal maturity. METHODS: Nonsyndromic patients undergoing primary modified Furlow palatoplasty between 1985 and 2005 with post-operative speech evaluations were retrospectively reviewed. Secondary speech surgery and Pittsburgh Weighted Speech Scale (PWSS) scores prior to secondary speech or orthognathic surgeries were assessed in the 5-7, 8-11, 12-14, and 15+ age groups and analyzed by Veau cleft type...

BACKGROUND: Direct-to-implant (DTI) reconstruction has multiple advantages over a staged tissue expander (TE) approach. However, its use may be limited by concerns of increased complications. This study is the largest series to date comparing postoperative outcomes for DTI versus TE reconstruction in the prepectoral plane. METHODS: The authors retrospectively reviewed 348 patients that received 536 total immediate, prepectoral implant-based breast reconstructions between January 2018 and December 2021...

BACKGROUND: The standard procedure for the management of skeletal class III malocclusion is maxillary advancement with mandibular setback. Occlusal plane altering orthognathic surgery, such as jaw rotation, is useful as well. Although clockwise jaw rotation is a common procedure, its mechanism has not been well-investigated. Therefore, in this study, we aim to introduce the gearing effect to correct class III malocclusion in Asians by maxillary posterior impaction via clockwise rotation without advancing the maxilla...

PURPOSE: To evaluate the recovery of lingual nerve (LN) neurosensory function in patients undergoing sagittal split osteotomy (SSO) with a low and short medial horizontal cut. MATERIALS AND METHODS: This was a prospective study of patients with mandibular deformities undergoing SSO with a low and short medial horizontal cut over a 4-year period. The outcomes of interest were neurosensory recovery of the LN, as assessed objectively using functional sensory recovery (FSR) and subjectively by patient report...

The two most common techniques for gender affirming mastectomy are the double incision free nipple graft and peri areolar. There are however patients that are not well suited for either technique. When the nipples are high and on the pectoralis muscle yet there is marked breast tissue and skin redundancy, a double incision free nipple graft would land the incision above the pec shadow but a peri-areolar approach would not adequately remove the excess skin. In these patients, a nipple-preserving inferior ellipse incision allows for appropriate chest contouring leaving the nipple position unchanged and placing the incision in the pectoralis muscle shadow...
