Pilonidal sinus is a common chronic benign
surgical condition affecting young males with thick,
coarse body hairs, deep natal cleft and involved in
profession requiring prolonged sitting like drivers..
It is associated with lot of distress and morbidity
leading to loss of wages. There are many different
modalities of surgical treatment of the disease and
simple excision, followed by regular dressing for
secondary healing is most commonly used method.
Present study was designed to compare Z-plasty with
simple excision in chronic pilonidal sinus. Z-plasty
is associated with early healing (16.6 days versus
42.2 days) and low recurrence rate(6% versus 20 %).
However, operating time (62.4 versus 34.8 minutes)
and post-operative stay (8.4 versus 5.9 days) was
slightly prolonged in Z-plasty.
