Open Excision for Pilonidal Sinus
Wide surgical excision of the pilonidal sinus with the wound left open to heal by granulation — highest cure rate for complex, recurrent cases.
About This Treatment
Open excision is the classical surgical treatment for pilonidal sinus. The entire sinus — including all tracts, pits, and hair-containing tissue — is excised with a margin of normal tissue, and the wound is left open to heal naturally by granulation from the base upward.
While open excision has the longest healing time (6–12 weeks of daily wound packing), it offers the highest cure rate (90%+) because it removes all disease. It is particularly recommended for extensive sinuses with multiple tracts, recurrent cases after previous surgery, and sinuses with secondary infection or abscesses.
At Shraddha Hospital, we optimize open excision outcomes with careful wound management, specialized nursing dressing protocols, and post-operative laser hair removal.
