A Giant Facial Nerve Schwannoma Extending from the Middle Cranial Fossa to the Mastoid Region: Case Report

Abstract

Facial nerve schwannomas are uncommon benign tumours and seldom extend into the middle cranial fossa. This is a case report of a giant facial nerve schwannoma extending from the middle cranial fossa to the mastoid region, which was successfully removed using combined interdisciplinary subtemporal and transmastoid approaches. Complete resection of the tumour was the optimal therapy for this patient because the facial nerve had been severely destroyed by the tumour. The clinical presentation, histological features, radiological findings and management of this case, as well as the relevant literature, are presented.
