Treatment of pilonidal sinus disease with the Z-plasty procedure (modified)

This article points out the significance of the internatal cleft for the formation of pilonidal sinus. Elimination of the internatal cleft by means of Z-plasty carries the smallest recurrence rate. The author, in an attempt to eliminate this small recurrence rate, applied a modified Z-plasty which is described in the present communication, and which was successfully applied in a series of cases of pilonidal sinus.
