A pilonidal cyst is an abnormal growth in the skin that usually contains hair and skin debris. It is located at the extreme end of the tail bone and at the top crease of the buttocks above the sacrum. It usually occurs when hair perforates the skin and gets embedded in it. The fluid filled sac which is formed can get infected and form an abscess which is often very painful.

It is more common in men than women and occurs at a young age.

Pilonidal Cyst Symptoms

Pilonidal Cyst Causes

The exact cause of these cysts is still not clear. However, some doctors believe that these cysts are present since the time of birth and arise from embryologic cells. They are caused by a combination of changing hormones, penetration of loose hair in the skin through dilation of hair follicles into the subcutaneous tissues. In response to the infiltrated hair, an inflammatory reaction causes a cyst like structure to form around the affected area and the skin debris.

In some cases, the cyst becomes infected and immediate hospitalization is required in such cases.

Pilonidal Cyst Treatment

It is important to understand that antibiotics do not heal a pilonidal cyst. However, there are few procedures and treatments that can be used to treat them.

Incision and Drainage :- The most preferred technique for treating a pilonidal cyst is creating an incision and draining the cyst which included removing the hair follicles and debris that are a part of it. It is a very simple procedure that is done under the administration of local anaesthesia. Post-drainage, the treated area demand a lot of care which includes frequently changing the bandage until the cyst heals completely.

Marsupialization :- This procedure involves creating an incision, draining the pus, hair follicles and debris and sewing the edges of the fibrous tract to the edges of the wound to make a sac. This procedure minimizes the size and extent of the wound and requires at least six to eight weeks for the wound to heal completely.

Treatment of the infection :- If the cyst is severely infected, the doctor may prescribe a course of antibiotics. However, this will not heal the wound completely but will give you relief from pain and infection.

Phenol Injection :- This procedure involves administration of local anesthesia first, followed by a phenol injection which acts as an antiseptic for the cyst. This procedure may need to be repeated several times, until the cyst abrasion becomes stiff and closes. The only disadvantage being that the rate of re-occurrence is high in this case.
