What is a pilonidal sinus / cyst?

Pilonidal sinus / cyst is a disease that occurs in the buttock area and manifests as a lump, which sometimes hurts, creates discomfort (especially when sitting), and sometimes has a discharge. It is more common in men. Risk factors are: increased hairiness, obesity, increased sweating, prolonged sitting.

Why does the pilonidal sinus form?

The cause of the pilonidal sinus is not clear, but inflammation of the hair follicles is thought to occur. Hair no longer grows normally, but bends and remains under the skin.

Is it a dangerous disease?

The disease is benign and manifests as an acute and chronic form.

How does the disease manifest itself?

Acute inflammation – redness, painful “pimple”, bloody or purulent discharge, unpleasant smell of discharge.

Chronic inflammation –  after acute inflammation, a small duct usually remains, which may sometimes have a discharge. With each new acute inflammation, the disease spreads in depth.

How is the pilonidal sinus / cyst treated?

In the acute phase, the surgeon incises and cleans the pus buildup. The wound is NOT sutured, but is allowed to heal slowly over several days.

In the chronic phase, the surgeon has several techniques available. The most common technique is to excise the sinus / cyst, leaving the wound open to heal slowly. The disadvantage of this method is the slow healing of the wound (several months) and the long absence from work.

At the Aster Polyclinic, the treatment of the pilonidal sinus is performed with a laser. This is the latest method, minimally invasive, almost painless, and wound healing is faster and recovery shorter. After surgical treatment, return to work is in a few days.
