title: [Nasal dermoïd cyst with intracranial extension: which approach?].
abstract: Dermoïd cyst is the most common midline congenital nasal tumor. Intracranial extension is rare but possible, must be suspected and confirmed by a cerebral magnetic resonance imagining (MRI). Only total surgical removal via a combined intracranial/extracranial approach appears to provide a complete resolution and effective protection against late recurrence. We report a case of a 2 years old patient who was operated for a nasal congenital cyst extending to the nasal septum. Anatomopathology showed a dermoïd cyst. Five years later, he presented local recurrence of the dermoïd cyst with intracranial extension through a bifid crista galli. We conclude that to avoid recurrence, the removal of the nasal cyst and sinus tract must be followed to its dural attachment. A transfacial approach can be associated with frontal craniotomy, which can provide adequate exposure for complete removal of the intracranial component of the cyst and sinus tract. A literature review was performed.
