1. What is Pilonidal Sinus?
A Pilonidal Sinus (PNS) is a small tunnel or tract that develops under the skin, usually near the tailbone at the top of the buttocks crease. This sinus often contains hair, debris, or dead skin cells, leading to infection, pain, and swelling.
The term “pilonidal” literally means “nest of hair”, which explains why hair growth and ingrown hairs are common contributors.
When infected, it can form a painful abscess that may discharge pus or blood. Though more common in men, it can affect anyone, especially those who sit for long hours.
Dr. Prosenjit Choudhury, an experienced General & Laparoscopic Surgeon in Kolkata, at Top Laser Clinic, specializes in advanced laser treatment for Pilonidal Sinus—offering fast recovery and minimal discomfort.
2. Symptoms of Pilonidal Sinus
Recognizing the early signs helps prevent severe infection. Common symptoms include:
- Pain or tenderness near the tailbone
- Swelling and redness in the affected area
- Discharge of pus or blood with a foul odour
- Formation of multiple sinus tracts
- Difficulty sitting or walking comfortably
- Fever in case of severe infection
If you notice these symptoms, consult a specialist immediately to avoid complications.
3. Types of Pilonidal Sinus

Pilonidal Sinus can appear in different forms depending on its stage and severity:
- Acute Pilonidal Abscess – A sudden, painful infection filled with pus that requires immediate drainage.
- Chronic Pilonidal Sinus – A long-standing infection that recurs after initial healing.
- Recurrent Pilonidal Sinus – Reappearance of infection after surgery or incomplete healing.
Modern laser treatment, offered at Top Laser Clinic, is highly effective for both acute and chronic cases.
4. Causes of Pilonidal Sinus
The exact cause is not always clear, but several factors contribute:
- Ingrown hair penetrating the skin
- Prolonged sitting or friction in the area
- Excessive sweating and poor hygiene
- Obesity and deep buttock cleft
- Wearing tight clothing
- Family history or genetic tendency
These causes create small openings that trap hair and bacteria, leading to infection.
5. Risk Factors
Certain groups are more likely to develop Pilonidal Sinus, including:
- Men aged 15–35 years
- People with thick or coarse body hair
- Office workers, drivers, or students who sit for long hours
- Individuals with poor hygiene or excessive sweating
- Those with repeated friction in the tailbone area
If you fall into any of these categories, preventive care is essential.
6. Diagnosis
Diagnosis is usually simple and can be done through a physical examination.
Your doctor will:
- Inspect the affected area for sinus openings or discharge
- Check for swelling, tenderness, or redness
- In chronic cases, imaging tests like ultrasound or MRI may be recommended to determine the depth and extent of the sinus
At Top Laser Clinic, Dr. Prosenjit Choudhury performs a thorough assessment before suggesting the best treatment approach, ensuring personalized care and accurate diagnosis.
7. Treatment Options

A. Conservative Management
In mild cases without infection, treatment may include:
- Maintaining hygiene and keeping the area clean
- Hair removal (laser or shaving)
- Antibiotic therapy if mild infection exists
However, conservative methods rarely provide a permanent solution.
B. Surgical Treatment
For infected or recurrent cases, surgery is necessary. Options include:
- Incision and Drainage – For acute abscesses, pus is drained to relieve pain.
- Excision Surgery – The sinus tract is surgically removed, and the wound is left open or stitched.
- Laser Pilonidal Sinus Treatment – The latest and most advanced option.
C. Laser Treatment for Pilonidal Sinus
This minimally invasive procedure involves using a laser fibre to close the sinus tract.
Benefits include:
- Minimal pain and bleeding
- No stitches required
- Faster healing and minimal downtime
- Low recurrence rate

8. Recovery after Treatment
Recovery depends on the treatment type:
- After Laser Surgery: Patients can resume normal activities within 24–48 hours. Minimal dressing is required, and pain is almost negligible.
- After Traditional Surgery: Recovery may take 2–4 weeks, with regular dressing and wound care.
Tips for smooth recovery:
- Keep the area clean and dry

Early diagnosis and advanced laser surgery significantly reduce these risks.
