Partial Mastoidectomy for the Safe Resection of Lateral Skull Base Tumors

Abstract

Facial nerve dissection and mobilization is often necessary in the surgical resection of parapharyngeal, infratemporal, or extracranial jugular foramen tumors. Facial paralysis may occur as a result of a stretch injury at the stylomastoid foramen. Conversely, in an effort to protect the nerve, tumor spillage may occur, leading to the disastrous complication of disease recurrence.
