Résumé
Pilonidal sinus disease of the natal cleft is a painful debilitating condition which often recurs despite different surgical procedures. In this thesis, the outcome of different methods for treatment of this disease are described and compared. A review of sixty patients were randomized into three groups. Group A were operated upon by sinus excision and leaving the resultant cavity to heal by granulation tissue. Group B were operated by excision with primary closure in natal cleft. Group C were operated by excision with oblique closure by z-plasty. Recurrence was highest in group B [25%] followed by group A [15%] and no recurrence occurred in group C. The mean satisfaction grading was 5, 2 in group A, 7.1 in group B and 9.3 in group c. Excision of pilonidal sinus and oblique closure by z-plasty offers improved patient satisfaction and no recurrence rate
