Pilonidal Sinus-Unroofing
摘要
In 1880, Hodges coined the term pilonidal, “pilus” meaning hair and “nidus” meaning nest. Pilonidal disease occurs when hairs, trapped beneath the sacrococcygeal skin, create an abscess that may rupture, leaving a chronically draining sinus. The condition is seen most commonly in young adults. Anatomic features that predispose to the development of pilonidal disease include a deep natal cleft, a hirsute body habitus, obesity, moisture, bacteria, and midline depressions or “pits” that trap hairs. Pilonidal sinuses may be treated by unroofing.
