ABSTRACT
Objective:
to describe and analyse a case of intrapetrous facial schwannoma, with intraparotid extension. Description a 37-year-old female came to examination presenting a facial palsy consequent to a previous surgery of a tumor in the left parotid region. Pathology revealed a schwannoma. CT-scanning and MRI showed an intratemporal left region mass.Intervention through a retro-auricular, transmastoid approach, it was observed that the tumor affected the labyrinthine and tympanic segments of the facial nerve. The intrapetrous mass lesion was removed but it was impossible to isolate a healthy portion of the nerve; intraparotid involvement was also observed. It was decided to perform a hypoglossal facial anastomosis using anautologous sural nerve grafting. Pathology of the intrapetrous lesion revealed a facial nerve schwannoma.Conclusion:
the choice of a retro-auricular, transmastoid approach allowed us to remove the facial nerve schwannoma, at the intrapetrous level. Due to the simultaneous intratemporal and intraparotid nerve involvement, a hypoglossal facial anastomosis was performed to treat the patients facial palsy.
