[Intraoperative monitoring of hearing function in the removal of cerebellopontine angle tumor: auditory brainstem response and cochlear nerve compound action potential].

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… (More)
