SummaryA new surgical technic for treatment of pilonidal sinuses is presented and results of its use in 110 patients are evaluated. This excisional technic with partial closure (midway between an open operation and a primary closure) compared favorably with the marsupialization operation in healing time, in lack of morbidity, and in low recurrence rate. The technical steps in the procedure are outlined. The operation is particularly indicated where the tracts are small, tortuous or ill‐defined.
