The sacrococcygeal cyst (or pilonidal cyst ) is the consequence of the accumulation and penetration of hair under the skin at the top of the intergluteal fold . The hair promotes infection (abscess formation), fistulas and cysts . These often open on the surface of the skin and away from the point of penetration of the hair.
The risk factors for sacrococcygeal cyst are male gender, hairiness, overweight and prolonged sitting. These lesions are often infected by the penetration of bacteria and cause the formation of painful abscesses.
Treatment of abscesses by surgical drainage
In the event of an abscess, surgical drainage is obtained through an incision under local anesthesia. Once the acute infection has healed, or in the case of an uninfected sacrococcygeal cyst, treatment consists in removing the fistulas under general anesthesia. Depending on the extent of the disease, several techniques are available, with more or less extensive resections, requiring in the most severe cases reconstruction with a skin flap. To avoid recurrence, hair removal by creams or laser is advised; shaving with a razor is not recommended.
