What is Pilonidal Disease?

Pilonidal disease is a chronic skin infection that occurs when hair follicles in the area between the buttocks become plugged up. Hair or skin debris become lodged in the sinus tract and begin to “pit”. The area subsequently becomes inflamed and tracts are created that can cause a “sinus”. Bacteria can enter the tract causing an infection or abscess. Pits commonly occur near the tailbone due to greater skin friction. Pilonidal disease is relatively common in teens and young adults and affects boys more often than girls. 

Symptoms of Pilonidal Disease:

Pilonidal disease often appears as a lump or swollen area that hurts when pressed with a finger. Pus or blood may or may not be draining from the lump. In some cases, a child may have a lump with some drainage and no pain. If the area becomes infected, the pus will be foul smelling and the area around it may become red and tender. This is typically painful, especially when sitting. Some people may experience a small degree of pain when sitting, while others will be in severe pain.

Pilonidal Disease Treatment

Treatment options for pilonidal desease depend on severity and individual needs. Our treatment plans begin with improved hygiene and hair removal as needed, which can be managed in the clinic without surgery.

Draining the Pus: Infection may be present, where surgery may be required to drain pus and fluid. Soaking in a warm tub or rinsing the infected area 1-2 times a day is highly recommended. 

Removing the “pits:" Pit picking is when the opening of the sinus tract is removed, allowing for the cavity to be cleaned out to drain the infection and remove any trapped hairs. 

Hair Removal: There are multiple methods of hair removal from the area of concern, including shaving, chemical hair removal and laser hair removal.
