Management of Pilonidal Sinus Disease with the Aesthetically Shaped Parasacral Perforator Flap: Multicenter Evaluation of 228 Patients

Benoit Chaput et al. Plast Reconstr Surg. 2019 Oct.

Abstract

Background: The management of pilonidal sinus disease is still not standardized. Currently, the two main procedures are a lay-open excision procedure with secondary healing or coverage with local flaps. The authors present their experience with a one-stage excision-coverage with an innovative parasacral artery perforator flap propeller designed to respect the aesthetic unity of the buttocks.

Methods: Study patients were managed with this procedure in the Toulouse, Montpellier, and Rennes university hospitals between 2012 and 2018. Data were collected on clinical and surgical details, immediate and late postoperative complications, and long-term recurrence. Aesthetic satisfaction was evaluated with a self-evaluation questionnaire.

Results: The authors operated on 228 consecutive patients for pilonidal sinus disease with an aesthetically shaped parasacral artery perforator flap. The median patient age was 23.5 years, the median operative time was 46 minutes, the median flap length was 9.3 cm (range, 6.5 to 14 cm), and the median flap width was 4.1 cm (range, 4 to 6.5 cm). There were five distal necroses but no complete flap necrosis. There were six postoperative hematomas, 11 infections, and 18 wound dehiscences. The median follow-up period was 27.9 months. Median hospital length of stay was 4.2 days. Three recurrences of pilonidal sinus disease and six instances of hidradenitis suppurativa were detected. Approximately 82 percent of the women and more than 85 percent of the men were "satisfied" or "very satisfied" with the aesthetic outcome, without significant differences between the sexes (p = 0.901).

Conclusions: The aesthetically shaped parasacral artery perforator flap combines very satisfactory results regarding recurrence and postoperative recovery with cosmetic outcome. This procedure is technically more demanding than other flap procedures, although it is accessible to numerous surgeons as the first-line treatment for pilonidal sinus disease after initial learning.

Clinical question/level of evidence: Therapeutic, IV.
