FIVE OPERATED CASES OF PILONIDAL SINUS

Abstract

We have experienced five operated cases of pilonidal sinus in a 8-year period from 1987 to 1995. All patients are slightly corpulent, younger males with hairy constitution. Four out of the five cases had undergone inappropriate treatments under a wrong diagnosis of anal fistula, abscess in the sacrococcygeal area, or suspected actinomycosis. Operative procedures included rotetion flap method attached to fascia of major gluteus muscle for four cases, and marsupialization for one case. Basic ideas of operation for pilonidal sinus are complete excision of the original foci, prevention of dead cavity, avoidance of tense skin suturing. The rotation flap method is rational, because reduction in the tension of skin suture is achieved by suturing fascia of the gluteus maximus muscle previously. On the other hand, the marsupialization is rational in the meaning of prevention of dead cavity formation, because the marginal skin and bottom of the wound is sewed up previously that contributes to a reduction of wound area. Both the rotation flap method attached to fasica of the gluteus maximus muscle and the marsupialization are effective operative methods for pilonidal sinus.
