Pilonidal Sinus Disease

What is Pilonidal Sinus Disease, and how can laser treatment reduce recurrence after surgery.

A Pilonidal Sinus is a small hole or "tunnel" in the skin. It usually develops in the cleft of the buttocks where the buttocks separate, causing the formation of a cyst or abscess. A Pilonidal Cyst usually contains hair, dirt, and debris. If it becomes infected, it may ooze pus and blood and have a foul odour.

More than one may develop, and often these are linked by tunnels under the skin.

A Pilonidal Sinus will not usually cause any noticeable symptoms unless it becomes infected. This can cause a pus-filled abscess to develop. Signs that you may have an infection include pain, redness and swelling in the affected area.

Why do Pilonidal Sinuses happen?

The exact cause of a Pilonidal Sinus is unclear, although it's thought to be caused by loose hair piercing the skin. 

Certain things can increase your chances of developing a Pilonidal Sinus, such as being obese, having a large amount of body hair, and having a job that involves a lot of sitting or driving.

Activities that cause friction, like sitting, can force the hair growing in the area to burrow back under the skin. The body considers this hair foreign and launches an immune response against it, similar to how it would react when dealing with a splinter. This immune response forms the cyst around your hair. Sometimes a person may have multiple sinuses that connect under the skin.

How is it treated, and after treatment, how do you stop recurrence?

Pilonidal Sinus Disease (PSD) is an inflammatory condition, primarily treated with surgery, but with a high rate of recurrence. 

Research has shown that lasers can reduce the rate of recurrence (see Marza L (2013) Reducing the recurrence of Pilonidal sinus disease, Nursing Times article

This is an effective treatment for Pilonidal cysts, providing excellent results with quick healing and no risk of serious adverse side-effects.
