Rhomboid flap procedure for pilonidal sinus: results from 67 cases.

Sixty-seven patients with chronic pilonidal sinuses were treated by excision and rhomboid flap transposition (RFT). Primary healing was obtained in all patients except two who developed a seroma and one who had a partial dehiscence of the surgical wound due to a hematoma, which necessitated drainage through the margin of the flap. The average stay was 5.3 days (range 1-16). All patients returned to normal activities within 2 weeks of surgery. No late recurrence occurred after a mean follow-up of 74.4 months (range 8-137).
