What is pilonidal disease?
Pilonidal disease is a chronic or ongoing skin infection in
the crease between the buttocks near the tailbone. It occurs
when hair grows under the skin.
Pilonidal disease is more common in men, usually between the
teenage years and 40 years of age. It is more common in
people who are overweight or have thick, stiff body hair.
What are the symptoms?
Symptoms might range from a small tender dimple to a large
painful area. Sitting may be painful. There may be fluid
that drains from the area that is clear, cloudy, or bloody.
The area may become infected and form an abscess. Symptoms
of an abscess may include:
- pus that oozes from the area
- redness
- tenderness and
- sometimes fever, weakness, or nausea
How is it treated?
A healthcare provider will usually drain the abscess. After
an abscess has been drained, it is very important to keep
the area clean. The area should be shaved or a hair removal
agent applied every 2 to 3 weeks. This will keep the hairs
from growing under the skin again.
After an abscess has been drained, a space under the skin
may form. This space is called a pilonidal sinus. The sinus
connects to the skin with one or more small openings.
Sometimes the sinus may get better by itself. Most of the
time it has to be removed. A few people may even have
several more infections in this area. These infections can
cause swelling, pain, and have fluid draining from them.
When an infection occurs, it almost always needs surgery.
When the pilonidal sinus has to be removed, it is usually
done as an outpatient procedure. The sinus area may be
stitched shut after the sinus is removed. Sometimes it may
be left open to drain, and heal from the inside out. Another
type of surgical procedure is closed with flaps. Your
healthcare provider will discuss the options and help to
select the best procedure for your situation.
