Pilonidal Sinus – Laser Technique
A pilonidal cyst is a common benign condition located superior and posterior to the anal region.
Symptoms
• Pruritus
• Discharge
• Pain with redness and local swelling
It may occur at any age, although it is more frequently observed in younger individuals.
Factors such as dense hair growth, prolonged sitting and inadequate local hygiene are commonly associated with the condition.
Diagnosis is established through a simple clinical examination by a surgeon.
Patients diagnosed with a pilonidal cyst require surgical treatment, as no alternative therapy exists.
Surgical intervention prevents worsening of symptoms and the formation of sinus tracts, which can be particularly troublesome for patients.
Laser Technique
This is a newer surgical approach for pilonidal cyst management.
Through a very small skin opening (2–3 mm), the cyst cavity and any associated sinus tracts are cleaned.
A specialised laser device is then used to ablate the pilonidal cavity.
The procedure is performed under general or epidural anaesthesia.
Following laser ablation and removal of the cyst wall through the small opening, there is no large open wound and no sutures are required.
The small opening is left to heal by secondary intention.
Postoperative Course
• No postoperative pain is typically reported.
• No large wound is present.
Recurrence
Recurrence remains possible, as with all pilonidal treatments.
For 15–20 days, meticulous local hygiene with sitz baths is required.
This technique requires specific training and expertise from the operating surgeon.
