Surgical Management of Nasal Dermoid Lesions

Nasal dermoids are the most common congenital midline nasal lesions. They often present as a midline pit or nasal mass and arise from incomplete or failed regression of the dural diverticulum during embryogenesis. Management requires complete resection of the tract and an appropriate surgical approach is based on location, extent, and presence/degree of intracranial extension. Classically requiring an open craniotomy for resection, newer strategies employ a minimally disruptive approach to fully excise the lesion and the tract to prevent recurrence.
