Surgery for Pilonidal Sinus

What is Pilonidal Sinus?

Pilonidal sinus is a condition that affects the area just above the buttocks called the natal cleft. When loose hairs fall off from the neck and back, they accumulate in the natal cleft. Sometimes, they make small holes in the skin or get into the existing pores. Hairs carry bacteria and thus they can infect the holes or pores of the skin. At times, the infection results in the formation of an abscess or a discharge that is released out on to the skin through a tunnel called the sinus.

Occasional discharge can be treated with antibiotics but surgery is the most effective way to remove pilonidal sinus. The operation is performed under general anesthesia and lasts for about half an hour. The surgeon removes the sinus along with the infected tissue.



Sometimes, surgery for pilonidal sinus can cause general complications like pain, bleeding, scarring and the formation of blood clots. Other complications may be a partial breakdown of the wound, numbness around the wound and slow healing.


Pilonidal sinus surgery is performed as an outpatient procedure and the patient is discharged the same day. Convalescence takes about two to three weeks, after which one can resume normal activities. Exercising in this period may speed up recovery. Talk to your doctor about an optimal workout regimen. Occasionally, pilonidal sinus makes a comeback
