What is Pilonidal Sinus?
A pilonidal sinus is a small cyst or abscess at the top of the buttocks (natal cleft), usually containing hair and skin debris. It can become infected, causing pain, swelling, and discharge. It most commonly affects young adults, especially men with sedentary lifestyles.
Symptoms
- Pain and tenderness in the buttock crease, especially when sitting
- Swelling and redness in the area
- Discharge of pus or blood with foul odour
- A small pit or opening in the skin
- Recurring infections and abscesses if untreated
- Fever in cases of acute abscess formation
Treatment Options
- Conservative care – For mild cases: hygiene, hair removal, lifestyle adjustments
- Incision and drainage – Emergency treatment for acute abscess
- Pit picking (Trephine procedure) – Minimally invasive for simple disease
- Laser treatment – Precise ablation of the sinus tract, minimal scarring
- Karydakis flap procedure – For complex or recurrent cases
- Bascom's cleft lift – For extensive pilonidal disease
Why Minimally Invasive Approaches?
- Less tissue damage and minimal scarring
- Shorter recovery — back to work in 3–5 days
- Lower risk of wound complications
- Daycare procedure — no hospital stay
- High patient satisfaction
- Very low recurrence compared to old open techniques
Prevention and Lifestyle Tips
- Keep the area clean and dry
- Maintain a healthy weight
- Avoid prolonged sitting; take regular breaks
- Regular hair removal from the natal cleft
- Wear loose, breathable clothing
- Early treatment of recurring infections
