Elliptical rotation flap for pilonidal sinus.

Background: The treatment of the symptomatic pilonidal sinus is surgical with one of the most extensive being excision of the diseased tissue down to the sacral fascia. The closure of the defect is the matter of debate. An elliptical rotation flap has been used for pilonidal sinus treatment with no recurrence rate.

Methods: From April 1996 to June 2001, 20 patients were treated with this technique. The surgical procedure is a vertical elliptical excision of the diseased tissue and an elliptical cutaneous rotation flap to close the defect.

Results: Twenty patients underwent with this technique, mean age 23.4 years (range 18 to 34). Mean follow-up was 42 months. All patients were discharged on the first postoperative day. Primary healing was achieved in all of the patients in 2 weeks. No recurrence was observed.

Conclusions: Elliptical rotation flap is recommended for patients selected for defect closure. It offers improved patient comfort, shorter hospital stay, and no recurrence rate.
