  • Title: Perineal perforator-based island flaps: the next frontier in perineal reconstruction.
    Author: Kim JT, Yew Ming Ho S, Hwang JH, Lee JH.
    Journal: Plast Reconstr Surg; 2014 May; 133(5):683e-687e. PubMed ID: 24776571.
    Abstract:
    BACKGROUND: Perineal reconstruction is a challenging prospect. Conventional flap reconstruction often involves the sacrifice of a source artery and muscle, resulting in significant donor morbidity. Perforator flaps sought to overcome this but required tedious dissection. In this article, the authors introduce a new concept in perineal reconstruction using perforator-based island flaps. METHODS: The perineal perforator-based island flap is raised based on perforators that most commonly arise from the perineal artery. The flap is designed in the inguinal and gluteal folds in order to achieve aesthetic, tension-free primary closure of the donor site. Eleven patients underwent perineal reconstruction using this approach. Patients ranged in age from 8 to 75 years, with a female-to-male ratio of 10:1. RESULTS: All 11 operations were performed by a single surgeon (S.Y.M.H.). There were no cases of flap loss or donor-site complications, as defined by wound infection, dehiscence, or keloid formation. All 11 patients reported excellent satisfaction with regard to donor-site aesthetics. CONCLUSIONS: Perineal perforator-based island flaps represent one of the most successful outcomes of the perforator concept. There is no sacrifice of donor vessels or muscle and minimal donor morbidity. The flap is also easily harvested and allows for challenging free-form flap design because it is based on reliable perforators. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
