Thirty-seven patients with chronic sinus pilonidalis were treated afte
r total excision by Dufourmentel flap. We saw seroma complications in
three and wound infections in two cases. Patients stayed in hospital 6
.3 days on an average and were able to work after 2.5 weeks. The metho
d is easy to use. We have not seen a return to sinus problems in any o
f this cases.
