Complete Guide to Pilonidal Sinus Treatment in Mumbai

Pilonidal sinus is a chronic condition that commonly affects young adults, particularly men between 15 and 35 years of age. It manifests as an abnormal skin growth or cyst near the tailbone (coccyx) that contains hair, skin debris, and sometimes pus. The condition is prevalent among people with sedentary lifestyles — office workers, drivers, and students who sit for long periods — making it particularly relevant in Mumbai's professional workforce.

What Causes Pilonidal Sinus?

The exact cause is debated, but the most accepted theory is that loose hairs penetrate the skin in the natal cleft (the groove between the buttocks), creating a foreign body reaction. Contributing factors include:

  • Prolonged sitting: Desk jobs, long commutes, and sedentary lifestyle
  • Excessive body hair: Particularly coarse or stiff hair in the sacrococcygeal area
  • Deep natal cleft: Anatomical predisposition
  • Obesity: Increased pressure and moisture in the area
  • Poor hygiene: Infrequent cleaning of the area
  • Previous injury: Trauma to the tailbone area

How Is Pilonidal Sinus Diagnosed?

Diagnosis is typically clinical — your surgeon will examine the area and identify the characteristic pit(s) near the tailbone. In complex or recurrent cases, an MRI may be recommended to map the full extent of the sinus tracts before surgery.

SiLaC Laser Treatment — The Modern Approach

SiLaC (Sinus Laser Closure) is a state-of-the-art technique that uses a radial-firing laser fibre to destroy the sinus tract from the inside. Here's how it works:

  1. Preparation: The sinus cavity is cleaned and debrided under anesthesia.
  2. Laser insertion: A thin laser fibre is introduced into the sinus tract.
  3. Ablation: The laser fires radially, destroying the epithelial lining of the tract and sealing it shut.
  4. Closure: The entry point requires only a small suture or is left to heal naturally.

The entire procedure takes 30–45 minutes and is performed as a day-care surgery at our Mumbai partner hospitals.

Post-Surgery Care and Prevention

After laser surgery, following these guidelines helps ensure complete healing and prevents recurrence:

  • Keep the area clean and dry — sitz baths as recommended
  • Hair removal (laser hair removal or regular shaving) around the surgical site
  • Avoid prolonged sitting for 2–3 weeks
  • Maintain a healthy weight
  • Wear loose, breathable clothing
  • Attend all follow-up appointments
