Pilonidal Disease
ICD-10 L05 · ICD-11 EG63

Treatment of Confirmed Pilonidal Disease of the Gluteal Cleft Without an Abscess

Clinical scenario: Confirmed pilonidal disease of the gluteal cleft, presenting without an active abscess.

When pilonidal disease is confirmed in the gluteal cleft and no abscess is present, a defined set of non-surgical interventions is available that targets the underlying cause and aims for durable resolution.

Treatment approach

Management involves targeted interventions directed at the gluteal cleft — including hair removal strategies and, where appropriate, local treatment of the affected tissue and tracts. The complete protocol specifies the method, sequencing, and number of treatment sessions required.

Clinical target: Complete resolution of pilonidal disease

  1. In patients with confirmed pilonidal disease without an abscess, hair removal from the gluteal cleft via shaving or laser epilation is a key treatment.
  2. The optimal frequency of shaving is unclear, but the ASCRS recommends at least weekly.
  3. It should be noted that a local anesthetic and more than one treatment session may be needed when opting for laser epilation.
  4. Local application of phenol also is an effective treatment option; it has been shown to resolve the condition in at least 67% of patients and prevent recurrences in at least 80%.
  5. Typically one to four treatments of hair removal, cyst curettage, and phenol application into the cyst and tracts can result in complete resolution of the condition.
