If a pilonidal sinus is small, then it may only require antibiotic treatment. If the sinus develops into an acutely inflamed abscess, then it will require drainage.

There are three alternative procedures that may be undertaken:

  • the lesion can be incised and laid open
  • the lesion can be completely excised
  • the lesion can be curetted and injected with phenol
