How is pilonidal sinus treated?

Pilonidal sinus is conventionally treated surgically by removing the involved area of skin and covering the defect with an adjacent flap of unaffected skin. At HAMS, pilonidal sinus is treated endoscopically – Endoscopic Pilonidal Sinus Treatment (EPSiT) or by Sinus Laser Closure (SiLaC).
