Abstract
Epidermoid cysts (ECs) are benign congenital cysts that typically develop from misplaced
stratified squamous epithelium during neural tube closure. They are most commonly
encountered in the cerebellopontine angle, the fourth ventricle, and the region of
the sella turcica. Recurrence of an EC or regrowth of residual components following
surgery is known to occur, but the exact incidence is not defined. Repeat surgical
removal is generally considered but may be complicated by significant morbidity. We
present a novel endoscopic method by which to manage a recurrent EC of the infratemporal
fossa using a silastic stent through a transpterygoid approach that permits periodic
drainage of recurrent cyst material in the outpatient setting with minimal morbidity.
