Pilonidal Sinus (Ingrown Hair Disease)

Pilonidal sinus is a chronic condition affecting the natal cleft, where small tracts form around trapped hair, leading to discharge, abscess and recurrent swelling. Treatment is individualised based on disease extent.

Symptoms

Discharge with an unpleasant odour from the natal cleft
Recurrent swelling, redness and pain
Acute abscess episodes requiring drainage
Small openings (pits) on the midline

Treatment approach

Acute abscesses require drainage. Definitive management ranges from minimally invasive techniques and laser-assisted approaches to classical excisional surgery. Long-term recurrence prevention depends on technique selection and post-procedure hygiene.

Frequently asked questions

Does pilonidal sinus recur?

Recurrence is possible. The risk is influenced by disease extent, technique used and post-operative care.

What is the recurrence rate after pilonidal sinus surgery?

Recurrence rates vary by technique and patient factors. Minimally invasive laser-assisted approaches aim to lower recurrence; long-term hygiene and hair management remain important.
