β¦ Synopsis
In a series of 74 nasal dermoids, 45 (61%) were of the simple variety involving skin only. Twenty nine (39%) were of the complex variety with deeper tissue involvement requiring more extensive surgery. Of the 29 complex dermoids, 9 (31%) extended to the cribriform plate region but only 3 (10%) of these had an extradural extension. All of the complex nasal dermoids were adequately managed by a transnasal approach. On these findings a preliminary craniotomy should only be considered in exceptional circumstances.

The most common congenital midline nasal masses are dermoids, gliomas, and encephaloceles. 1 These are rare, and in the United States they occur in approximately 1:30,000 live births. 2 Gliomas and encephaloceles are of neurogenic origin, and dermoid cysts originate from ectoderm and mesoderm.
Background. Nasal dermoid sinus cysts are rare congenital lesions that result from aberrant embryonal development. Cases of nasal dermoids associated with intracranial extension have been reported in the past, but have almost always occurred in children. ## Methods. One case of a nasal dermoid cy
