Brief Summary

This study compares three different treatments for pilonidal sinus disease to determine which approach provides the best outcomes for patients. Pilonidal sinus is a condition where a small hole or tunnel forms in the skin at the top of the buttocks. It happens when hair gets trapped under the skin, causing pain, swelling, and infection. This condition mainly affects young adults and can interfere with work and daily activities. The study compares three minimally invasive treatments:

  1. 1.Laser therapy alone: A thin laser fiber is inserted into the sinus to destroy the lining and close the tunnel using local anesthesia as an outpatient procedure.
  2. 2.Phenol treatment alone: A chemical solution (phenol) is injected into the sinus to make it close and heal, done with local anesthesia in the clinic.
  3. 3.Combined laser and phenol therapy: Both treatments are used together for potentially better healing with lower recurrence rates.
