Pilonidal Sinus

A pilonidal sinus is caused by an ingrowing hair or hairs in the natal cleft (the dip between your buttocks). This may cause discomfort and discharge or may lead to formation of an abscess characterised by severe pain, redness and swelling and may require urgent surgical drainage.

Following draining of a pilonidal abscess or in the presence of ongoing discomfort and/or leakage, a number of surgical options are available to treat this condition.

These include simple drainage of an abscess or cleaning out of the hairs to wide excision of the diseased area. Sometimes this requires packing but it can often be stitched closed allowing more rapid healing if the appropriate techniques are used.
