ABSTRACT
Pilonidal sinus disease is a common, chronic intermittent disorder, with different theories regarding its etiology. There are different methods and procedures for the treatment. In current study, from January 2002 to January 2005, 32 patients were selected for the study. 2 cases were excluded. The surgical procedure is a vertical elliptical excision of the sinus and the diseased tissue and closure of the defect by rotational elliptical transverse flap without drain. There was neither recurrence rate nor other major complications. Mean follow up period was 14 months and hospital stay ranged from 12-24 hours. Elliptical rotation flap is recommended in selected cases for closure of the defect in case of pilonidal sinus disease with no recurrence rate and shorter hospital stay
