  • Look Inside

Intraoperative hearing monitoring may be the best approach for hearing preservation in the removal of cerebellopontine angle (CPA) tumors. We designed an intracranial electrode for a reliable and consistent recording of the cochlear nerve compound action potential (CNAP), and compared the efficiency of the CNAP and auditory brainstem response (ABR) while monitoring the CPA tumor removal. Simultaneous intraoperative monitoring of CNAP and ABR were performed in 7 patients with CPA tumors (5 acoustic neurinomas and 2 epidermoids) undergoing tumor removal aimed at hearing preservation.
