Care for inflammation in the natal cleft

Treating a pilonidal sinus according to its symptoms and form

A pilonidal sinus usually develops in the cleft between the buttocks when hairs enter the skin and cause inflammation. Small openings may cause no symptoms. Pain, swelling or recurrent discharge suggests a form that needs assessment.

Three different forms

A pilonidal sinus without pain or discharge does not require preventive surgery under current guidance. An acute infection can cause a very painful swelling and collection of pus within a short period.

Chronic disease may cause recurrent fluid, blood or pus from small openings in the cleft. The skin can become irritated and sitting uncomfortable.

Assessment and acute treatment

The history and examination of the cleft usually establish the diagnosis. Imaging is rarely needed for a typical presentation.

A painful abscess usually needs prompt opening so the pus can drain. Fever, rapidly worsening pain or spreading redness should be assessed on the same day.

Planning treatment for chronic symptoms

Surgery is considered for a chronically symptomatic pilonidal sinus. The number and location of openings, extent of disease, active inflammation and previous operations guide the choice of procedure.

Healing time, time away from normal activities and recurrence risk differ between methods, so treatment is selected after examination.

Frequently asked questions

Does every pilonidal sinus require surgery?

No. A finding without pain, inflammation or discharge does not usually need preventive treatment. Symptoms or an abscess change the recommendation.

Does an abscess need urgent care?

A painful collection of pus should be drained promptly. Seek same-day care if you have fever, rapid deterioration or marked redness.

Can a pilonidal sinus return?

Yes. Extent, treatment method and wound healing influence recurrence risk and should be discussed before surgery.
