Acne Help (Home) > Common Skin Disorders > Pilonidal Cyst Pilonidal Cyst: Infections, Causes, Symptoms and TreatmentDevelop when a dead hair or hairs are pushed into the skin forming a canal or passage. This sinus then becomes infected as more debris collects in the sinus. The most common place for a pilonidal cyst to develop is in the skin over the tailbone, just over the cleft in the buttocks. Friction and pressure on the area aggravate the condition along with the presence of bacteria. People are not born with this condition but develop it in the late teens, twenties or thirties. Trauma or injury to the are may cause the cyst to become very tender and painful, producing swelling and drainage. Pilonidal Cyst CausesMost doctors think that ingrown hairs cause pilonidal cysts. Pilonidal means "nest of hair." It is common to find hair follicles inside the cyst. Another theory is that pilonidal cysts appear after trauma to the sacrococcygeal region (the region relating to both the sacrum [the lower vertebrae] and coccyx). During World War II, more than 80,000 soldiers developed pilonidal cysts that required a hospital stay. People thought the cysts were due to irritation from riding in bumpy Jeeps. For a while, the condition was actually called "Jeep disease." Pilonidal Cyst SymptomsThe symptoms experienced by someone with a pilonidal cyst include the following:

Pilonidal Cyst TreatmentSelf-Care at HomeEarly in an infection of a pilonidal cyst, the redness, swelling, and pain may be minimal. Sitting in a warm tub may decrease the pain and may decrease the chance that the cyst will develop to the point of requiring incision and drainage. Medical TreatmentAntibiotics do not heal a pilonidal cyst. Doctors have any of a number of procedures available, including the following treatments. Incision and drainageThe preferred technique for a first pilonidal cyst is incision and drainage of the cyst, removing the hair follicles, and packing the cavity with gauze. Advantage - Simple procedure done under local anesthesia Disadvantage - Frequent changing of gauze packing until the cyst heals, sometimes up to 3 weeks MarsupializationThis procedure involves incision and draining, removal of pus and hair, and sewing of the edges of the fibrous tract to the wound edges to make a pouch. Advantages - Outpatient surgery under local anesthesia, minimizes the size and depth of the wound without the need to pack gauze in the wound Disadvantages - Requires about 6 weeks to heal, needs a physician trained in the technique Another option is incision and drainage with immediate closing of the wound.Advantages - Wound completely closed immediately following surgery without need for gauze Disadvantages - High rate of recurrence (It is hard to remove the entire cyst, which might come back. Typically performed in an operating room, it requires a specially trained surgeon.)
