Gluteus Maximus Musculocutaneous Flap for the Treatment of Recalcitrant Pilonidal Disease

Abstract

Although conservative surgery should be the initial approach to pilonidal disease, there remains a select group of patients with recalcitrant disease who fail repeated interventions and for whom a more aggressive approach is justified. Use of a large gluteus maximus musculocutaneous flap to facilitate wide excision, to allow for primary closure with well-vascularized tissue, and to alter the anatomy of the gluteal cleft has been used in 5 patients with chronic recurrent recalcitrant disease. The use of this large muscle unit in these otherwise healthy adults has achieved control over their pilonidal disease with acceptable morbidity and no demonstrable functional sequelae.
