Pilonidal Sinus

A pilonidal sinus is a small opening or cyst or abscess that occurs in the cleft at the top of the buttocks. It can cause severe pain and often becomes infected. If it becomes infected, it may exude pus and blood and emit a foul smell.

Though the exact cause remains unknown, few causes may be:

1. Hormonal (Few hormones at the time of puberty)

2. Hair growth or hair follicle infection 

3. Friction caused by tight clothes rubbing on prolonged sitting posture 

4. Infection 

Most common symptoms include:
  • Pain at the bottom of the spine
  • Swelling at the bottom of the spine
  • Redness at the bottom of the spine
  • Draining pus
  • Fever
 

Diagnosis can be made by physical examination. Other blood investigations are usually not required.

 

Individuals who are into occupations that involve:

Prolonged sitting, or driving are usually more prone to the condition.

For mild cases a course of antibiotics is advised.

For more severe cases, the following are recommended:

1. Lancing - cleaning and dressing 

2. Phenol injection - local injection 

3. Surgical excision of sinus 

4. Fibrin glue 

 

Condition can be prevented by the following measures:

 1. Maintainance of personal hygiene- washing the area with a mild soap and rinsing off the soap completely and patting dry

 2. Avoiding prolonged sitting 

 3. Avoiding driving for long distance 

 4. Keeping the area completely clean
