Alternative Abdominal Wall Plication Techniques: A Review of Current Literature.

Abdominoplasty is one of the most common procedures performed in plastic surgery. By removing redundant skin and fat tissue, body contouring narrows the waist and achieves a naturally flattened appearance. To achieve this, one technique frequently utilized is plication of the abdominal rectus sheath. Although abdominal wall plication is commonly performed during abdominoplasty, there is a lack of consensus regarding which plication method provides the best outcomes. Each variation addresses some of the common intraoperative and postoperative complications of abdominoplasty. These include extended operating time, rupture of the plication, epigastric bulging, and patient postoperative dissatisfaction. Many plication techniques have been described in the literature, but no single technique has been adopted by plastic surgeons as the gold standard. Here we present a narrative comparison of current published literature reporting novel or modified abdominoplasty plication techniques. This includes diagrams of each procedure, sutures utilized, and key concepts of each plication technique. Discussion regarding how these modifications change operating time, alter epigastric bulging, and improve the ability to narrow the waist is provided. The purpose of this paper is to provide a concise source document for plastic surgeons to reference when choosing a plication method to use during abdominoplasty.

Temporoparietal Fascia Graft and Polydioxanone Plate Repair of Nasal Septal Perforation.

BACKGROUND: Surgical repair of septal perforations has been historically cumbersome. Recently described techniques utilizing interposition grafting with polydioxanone (PDS) plates wrapped in a temporoparietal fascia (TPF) graft have reported successful closure in 90% to 100% of cases. Our objective is to expand the investigation into the use of interposition grafts of polydioxanone plates combined with a temporoparietal fascia graft for nasal septal perforation repair. METHODS: Retrospective review of the medical record was performed for all septal perforation repairs using the TPF-PDS plate interposition graft technique from August 1, 2017 to March 1, 2021 at the University of Iowa. Minimum post-operative follow-up was 1 month. RESULTS: Our series included 31 patients with symptomatic nasal septal perforations. Thirteen patients underwent open while 18 patients underwent endonasal graft placement. The mean perforation size was 1.49 cm2. The mean post-operative follow-up was 11.5 months. CONCLUSIONS: Repair of symptomatic nasal septal perforations using an interposition graft of polydioxanone plate wrapped in temporoparietal fascia demonstrated an overall success rate of 90%.

The Potential Role of Exosomes in Aesthetic Plastic Surgery: A Review of Current Literature.

Despite an increasing surge of exosome use throughout the aesthetic arena, a paucity of published exosome-based literature exists. Exosomes are membrane-bound extracellular vesicles derived from various cell types, exerting effects via intercellular communication and regulation of several signaling pathways. The purpose of this review was to summarize published articles elucidating mechanisms and potential applications, report available products and clinical techniques, and prompt further investigation of this emerging treatment within the plastic surgery community. Methods: A literature review was performed using PubMed with keywords exosomes, secretomes, extracellular vesicles, plastic surgery, skin rejuvenation, scar revision, hair growth, body contouring, and breast augmentation. Publications from 2010 to 2021 were analyzed for relevance and level of evidence. A Google search identified exosome distributors, where manufacturing/procurement details, price, efficacy, and clinical indications for use were obtained by direct contact and summarized in table format. Results: Exosomes are currently derived from bone marrow, placental, adipose, and umbilical cord tissue. Laboratory-based exosome studies demonstrate enhanced outcomes in skin rejuvenation, scar revision, hair restoration, and fat graft survival on the macro and micro levels. Clinical studies are limited to anecdotal results. Prices vary considerably from $60 to nearly $5000 based on company, source tissue, and exosome concentration. No exosome-based products are currently Food and Drug Administration-approved. Conclusions: Administered alone or as an adjunct, current reports show promise in several areas of aesthetic plastic surgery. However, ongoing investigation is warranted to further delineate concentration, application, safety profile, and overall outcome efficacy.

Head and Neck Reconstruction with Venous Flap: A Case Report.

Venous flaps are nonphysiologic flaps in which the venous system replaces the vascular circuit found in conventional flaps, serving as inflow as well as outflow. Although a main concern with venous flaps has been their reliability, this can be improved by manipulating their physiology using shunt restriction. The soft, pliable tissue provided by venous flaps coupled with the low donor site morbidity and ease of flap harvest make them ideal for coverage of moderate-sized facial defects, which may be too large for local options yet too small for conventional free flaps. We report the use of a large, 70 cm2 arterialized venous free flap to reconstruct a complex forehead deficit after basal cell carcinoma resection. Furthermore, we present the first report of the successful use of valvulotomes in the case of a large, reverse flow arterialized venous flap where several in-series valves were found to prevent adequate perfusion of the flap. Upon removal of the valves, complete perfusion of the flap was achieved.
