Pilonidal cyst, medically known as pilonidal sinus, is a chronic infection that usually occurs in the tailbone area due to the accumulation of hair, skin debris, and foreign matter under the skin. If left untreated, the infection may progress and lead to more serious complications. In this article, you’ll find everything you need to know about pilonidal sinus, including causes, symptoms, and modern treatment options.

What Is a Pilonidal Cyst?

A pilonidal cyst is an infected sac located under the skin, typically in the sacrococcygeal (tailbone) region. It often contains embedded hairs and debris, which can lead to inflammation, abscess formation, and chronic discharge.

What Causes Pilonidal Sinus?

Several factors can contribute to the development of pilonidal sinus:

  • Prolonged sitting
  • Excessive sweating and poor hygiene
  • Friction from tight clothing
  • Genetic predisposition
  • Dense body hair

The structure of the skin and hair in the coccyx area increases the risk of pilonidal cyst formation.

Common Symptoms

  • Pain and tenderness in the tailbone area
  • Redness and swelling
  • Foul-smelling discharge or bleeding
  • Discomfort while sitting or walking
  • In some cases, fever if abscess is present

What Is Pilonidal Sinus Abscess?

When the cyst becomes infected, it may turn into a pilonidal abscess, causing intense pain, visible swelling, and even fever. This condition requires urgent surgical drainage.

How Is Pilonidal Cyst Diagnosed?

Diagnosis is often based on physical examination. Small openings (sinus tracts) and discharge can be observed in the coccyx area. Imaging techniques such as ultrasound may be used when necessary.

Treatment Options for Pilonidal Cyst

1. Incision and Drainage (Cystotomy Surgery)

This emergency procedure is performed when an abscess is present. It relieves pain and controls the infection.

2. Sinusectomy (Cyst Removal)

After the infection subsides, the entire cyst is surgically removed. Both open and closed techniques can be used depending on the case.

3. Flap Surgery

In recurrent or wide lesions, tissue flaps may be rotated to close the wound, ensuring better cosmetic results and lowering recurrence risk.

4. Laser Treatment

Minimally invasive laser treatment is ideal for suitable patients. It causes minimal tissue damage, shortens recovery time, and leaves less scarring.

Comparative Table: Pilonidal Cyst Treatment Methods

Treatment Method When Applied Advantages Recovery Time
Cystotomy Surgery In abscess cases Rapid relief, infection control 1–2 weeks
Sinusectomy Full cyst removal Reduces recurrence, permanent solution 2–4 weeks
Flap Techniques Large or recurrent cases Aesthetic healing, low recurrence 3–5 weeks
Laser Treatment Suitable patient selection Minimal damage, fast recovery 1–2 weeks

Role of Laser Hair Removal in Prevention

To prevent recurrence after pilonidal cyst surgery, laser hair removal in the tailbone area is strongly recommended. Benefits include:

  • Reduction in hair regrowth
  • Lower recurrence risk
  • Improved hygiene and wound care

Our clinic provides specialized post-operative laser hair removal protocols to maximize treatment success.

Risks of Delayed Treatment

  • Untreated pilonidal disease may lead to:
  • Recurrent abscesses
  • Chronic discharge
  • Extensive infection of the surrounding tissue
  • Tissue damage and scarring
  • Early diagnosis and treatment significantly improve outcomes.

Recovery After Pilonidal Cyst Surgery

Recovery depends on the chosen surgical method, ranging from 1 to 5 weeks. Proper wound care, hygiene, and optional laser hair removal help reduce the chance of recurrence.
