Intraoperative Neurophysiological Monitoring Of Acoustic Neuroma
Hearing nerve (sheath) tumors, are the most common benign tumors found in the cerebellopontine angle (CPA). These tumors typically arise from the vestibular portion of the auditory nerve and are usually unilateral, with bilateral occurrences being rare. As these tumors grow slowly, they can exert pressure on nearby cranial nerves and the cerebellum, potentially displacing the brainstem and compressing the cerebral aqueduct, leading to serious complications such as cerebellar tonsillar herniation.
