TY - CHAP M1 - Book, Section TI - Excision of Pilonidal Sinus A1 - Ellison, E. Christopher A1 - Zollinger, Robert M. PY - 2016 T2 - Zollinger's Atlas of Surgical Operations, 10e AB - Pilonidal cysts and sinuses should be completely excised or exteriorized (figure 1a and b) . Acutely infected sinuses should be incised and drained, followed later by complete excision after the acute infection subsides. The more limited procedure of exteriorization (marsupialization) is effective when the sinus tract is well defined (figure 1b). Regardless of the various surgical approaches, such lesions may recur.
