Gluteal thigh flap repair of chronic perineal wounds.

Abstract

Since the introduction of the gluteal thigh flap in 1979, we have had the opportunity to study and modify this reconstructive technique in over 40 patients. Our successful experience with the gluteal thigh flap in six consecutive patients with difficult, nonhealing perineal pelvic sinuses has increased our confidence with this modality and led to a modified technique. Bilateral deepithelialized and well-vascularized flaps are harvested from the posterior thighs and transferred to the perineal wounds on pliable musculofascial pedicles through the ischiorectal space. Proper filling of the pelvic space requires adequate debridement, which may include release of a bottleneck narrowing of the sacral promontory. Donor site morbidity is minimal and temporary. Follow-up periods of 8 months to 5 years have revealed no wound recurrence.
