摘要: Intraoperative monitoring of cochlear compound action potentials (CAP) by transtympanic electrocochleography (ECoG) and direct recording from the nerve intracranially, when possible, was performed during 59 operations in cerebellopontine angle. Thirty were to remove acoustic neuromas a suboccipital hearing-preservation approach, 24 vestibular neurectomies (VN) treat Meniere’s disease, 5 nervus intermedius (NI) sections relieve chronic cluster headaches. Interpretable responses obtained most patients (93%).
