The exact cause of the pilonidal sinus is not known. Some people are born with a pit where hair is trapped between buttocks and with age sinus develops. In some cases the pit may develop with constant pressure.
Some of the conditions which increases the incedence includes
I follow a simple alogorithm for traetment of pilonidal condtionss
I offer the following surgical options depending on the condition
Both above procedures are simple with no other added complications and will be enough to treat about 90% conditions so I would always prefer to perform simple wide excision +/- primary closure for all the pilonidal conditions as a first choice.
If condition reccurs then a advanced procedure which involves mobilising and closure with flap can be performed.
Pilonidal sinus is minor condition but problomatic because of the place it affects.
