Abstract

Purpose: Cerebellopontine angle meningiomas (CPAMs) are benign tumors that arise from the dura mater of the petrosal surface of the temporal bone, lateral to the trigeminal nerve. This study aimed to describe 1 case of CPAMs violating the mastoid and highlight the unique superiority of the presigmoid transmastoid approach for this type of CPAMs from an otologist's perspective.

Methods: One case of specific CPAMs treated by total resection via presigmoid transmastoid approach in otomicrosurgery was described.

Results: A patient was referred for the left intracranial space-occupying lesion found in physical examination. Surgical resection via presigmoid transmastoid approach was performed and there was no sign of recurrence of tumor 2 years after the operation.

Conclusions: Presigmoid transmastoid approach in otomicrosurgery is suitable for CPAMs invading the mastoid. It is suggested that neurosurgeons and ear surgeons should comprehensively analyze the type and extent of the tumor and flexibly adopt surgical methods to ensure it is the best for patients.
