A pilonidal cyst is a cavity underneath the skin in the crease of the buttocks overlying the coccyx (tailbone). The cause of a pilonidal cyst is not completely understood, but is thought to be related to hair and debris getting caught in hair follicles beneath the skin.
Symptoms & Diagnosis
Some people have no symptoms. Others will note a small dimple in the area, clear or blood-tinged drainage, and/or discomfort. If the pilonidal cyst becomes infected, the area can become red, tender and can develop an abscess.
Treatment Options
- Infection of a pilonidal cyst may require antibiotics.
- If an abscess is present, it may require surgical incision and drainage. This can often be performed in the office with local anesthesia.
- Pilonidal cysts that are symptomatic (pain, persistent drainage, recurrent infections) may benefit from surgical excision (removal).
- Sometimes hair removal in the area of the pilonidal cyst is helpful.
Surgical excision of a pilonidal cyst:
- This procedure is done in the operating room. You can go home the same day.
- The goal is to remove the cyst and any sinus tracts associated with it.
- You will often have sutures that will need to stay in for 2+ weeks and are removed in the office. Sometimes a portion of the incision will need to be left open to heal in and may require local wound care.
- The healing time after a pilonidal cyst excision is usually 2-4 weeks, but in some cases can take longer.
- There is a small risk of the pilonidal cyst recurring after you have had surgery.
- This surgery will be discussed in more detail at an office visit with your Colorectal Surgeon.
