The initial treatment of a pilonidal cyst involves cyst drainage, which can be done at a doctor’s office. A local anesthetic is injected in the area around the cyst to make it numb. The doctor makes a small incision in the cyst and drains it. Some cysts reoccur after this procedure, requiring more extensive surgery, according to Mayo Clinic.

The goal of other procedures is to completely remove all cystic tissue and allow healthy areas to heal, explains Medscape. In simple cystectomy the tissue around the cyst is dissected towards the sacrum. The area around the cyst is exposed and a bit of healthy tissue is dissected laterally to make sure that the entire cyst and sinus tract are exposed. The area is either kept open and protected with negative pressure gauze, or closed with sutures.

A variety of surgical techniques may be indicated for complicated or recurrent disease, such as the Bascom procedure, Z-plasty, Y-V plasty, the Karydakis flap, the Limberg flap or the myofasciocutaneous gluteal flap, according to Medscape.
