Surgery for pilonidal cyst
A pilonidal cyst is a pocket that forms around a hair follicle in the crease between the buttocks. The area may look like a small pit or pore in the skin that contains a dark spot or hair. Sometimes the cyst can become infected, and this is called a pilonidal abscess.

An infected pilonidal cyst or abscess requires surgical drainage. It will not heal with antibiotic medicines. If you continue to have infections, the pilonidal cyst can be removed by surgery.
There are several types of surgery.
Incision and drainage -- This is the most common treatment for an infected cyst. It is a simple procedure done in the doctor's office.
Pilonidal cystectomy -- If you keep having problems with a pilonidal cyst, it can be removed surgically. This procedure is done as an outpatient procedure, so you will not need to spend the night in the hospital.
It may be hard to remove the entire cyst, so there is a chance that it will come back.
