First developed for coverage of burn wounds, Integra (Integra LifeSciences) is a synthetic acellular dermal regeneration template that provides a base for revascularization and neodermal formation. The use of Integra has slowly grown and has now become an important consideration along the reconstructive ladder. This article reviews the basic science of Integra and provides an overview of the many expanding applications based on anatomic location.

Scarless healing has long been the holy grail for plastic surgery. While historically fetal surgery has tempted plastic surgeons with the allure of scarless correction of congenital abnormalities, the risks far outweighed the benefits and these interventions never materialized. Current advances in fetal surgery with minimally invasive fetoscopic surgery have made these early fetal interventions safer, leading to expanding applications. While the plastic surgeon's role is limited as of yet, this article provides a review of the history of fetal surgery and the advances that may become relevant to the future plastic surgeon.

Background: Autologous breast reconstruction using perforator flaps offers excellent outcomes, minimizes donor-site morbidity, and allows for precise donor-site selection. The deep inferior epigastric artery perforator, profunda artery perforator, and gluteal artery perforator flaps along with the stacked flap technique are the most common options. This study reports the first series of the stacked lateral thigh perforator flap. Methods: A retrospective review of all stacked lateral thigh perforator flaps done by a single group of surgeons was performed. Demographics, flap weights, complications, indications, and surgical technique were tabulated for each patient. Results: Eight female patients with a history of breast cancer underwent delayed unilateral breast reconstruction with stacked lateral thigh perforator flaps for a total of 16 flaps. Mean patient age, body mass index, flap weight, and stacked flap weight were 47.3 years, 26.2 kg/m2, 333.1 g, and 666.1 g, respectively. Microsurgical revascularization was completed in anterograde and retrograde fashion to the internal mammary vasculature. Flap survival was 100 percent and one subsequent flap revision was performed. Two patients developed a seroma at the donor site. Indications included insufficient abdominal tissue, prominent lateral thigh lipodystrophy, prior abdominal surgery, and failed prior abdominally based autologous reconstruction. Conclusions: This series demonstrates that the lateral thigh perforator flap is a reliable and effective option for a stacked breast reconstruction. Its ease of harvest (stemming from reliable anatomy), straightforward dissection, and intraoperative positioning make it an appealing flap option. The stacked lateral thigh perforator flap allows the reconstructive surgeon to tailor breast reconstruction to the patient, focusing on body habitus and minimizing morbidity. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
