title: Cosmetic closure of pilonidal sinus defects with bilateral transpositional adipofascial flaps.
abstract: The optimal treatment of the pilonidal sinus has not currently been defined. This study described the use of a modified bilateral transpositional adipofascial flap technique that effectively serves to flatten the deep natal cleft while keeping the scar limited to the intergluteal fold for good cosmesis. Between June 2007 and September 2011, 83 patients (61 men, 22 women) were included in the study. Duration of pilonidal sinus symptoms ranged from 1-15 (median 5) years; 15 patients had recurrent disease. Before the operation, perforating branches of the four pairs of lateral sacral arteries were identified with a Doppler audioscope. After complete excision of the sinus cavity and adequate undermining of the skin, bilateral adipofascial flaps were raised in order to realise a Yin-Yang pattern, with the lateral sacral artery perforators at the base of each flap. Complementary flaps were then transposed into the defect and inset to completely obliterate dead space. Skin was closed primarily in two layers. The median (range) defect size after total excision of the sinus cavity was 38 (19-60) cm2. All flaps survived. There was no wound infection or dehiscense. Median (range) follow-up was 26 (6-52) months. No recurrences were observed. Extensive scarring or asymmetry in the gluteal prominences was not observed. Transient paraesthesia over the flap donor region occurred in 14 cases (16%) and resolved completely within 6 months. The bilateral adipofascial transpositional flap method is an alternative to previously described treatment options in pilonidal sinus surgery. It is a safe, reliable, and easily applicable method, which provides cosmetically acceptable coverage of pilonidal sinus defects of moderate size.
