Abstract:
Symptomatic pilonidal sinus is characterized by an acute or a chronic inflammation. The surgical management of symptomatic pilonidal sinus is still a matter of discussion and no clear recommendations exists. On the basis of results from published studies and our own experience we developed a new two step therapy concept: Infected pilonidal were first drained by a small excision of the abscess (if possible in local anesthesia) followed by a close fistula excision. With this approach we were able to achieve a low morbidity and a high healing rate. In the case of extensive fistulating pilonidal sinus or recurrent disease we recommend radical excision and primary reconstructive flap what showed good aesthetic results.
