[Retrospective study 10 years after plastic surgery for sacrococcygeal pilonidal sinus].

The authors give a brief summary on the etiology and pathomechanism of the sacrococcygeal pilonidal sinus. They have distinguished the congenital, cystic deformation (dermoid cyst) from the pilonidal sinus which is considered to be an adventitious illness. During ten years (1976-1985) 208 patients were operated on with the method the authors applied. Only one early recurrence was registered and 7.2% of the patients recovered from secondary healing. Delayed recurrences were analysed according to questionnaires. From 151 of the questionnaires only three male patients complaints referred to delayed recurrence.
