Surgery for pilonidal sinus

2-minute read

This page will give you information about surgery for a pilonidal sinus. If you have any questions, you should ask your GP or other relevant health professional.

What is a pilonidal sinus?

A pilonidal sinus is a problem in your natal cleft (the area between your buttocks).

Hairs can grow in your natal cleft, or loose hairs can fall and collect in your natal cleft. Hairs carry bacteria, which can cause inflammation and infection. An abscess can form or the pus can drain through a tunnel (sinus) out to your skin.

What are the benefits of surgery?

Washing your natal cleft every day may help to prevent an infection.

An occasional discharge can be treated with antibiotics.

It is sometimes possible to have a procedure to drain an abscess.

What does the operation involve?

The operation is performed under a general anaesthetic and usually takes about 30 minutes.

Your surgeon will remove the sinus and infected tissue.

What complications can happen?
