Epilepsy(癫痫) Nonvertiginous labyrinthine disease affects primarily the cochlea and includes the following 1. Congenital and neonatal hearing loss 2. Familial deafness Presbycusis(老年性耳聋) 4. Drug toxicity 5 Ototropic viral disease(耳带状疱疹) 6. Noise-induced hearing loss 7. Sudden idiopathic hearing loss(突发性耳聋) 8 Otosclerosis(耳硬化症) Examination of the patient with labyrinthine symptoms(vertigo hearing loss, and tinnitus)should include caloric examination and hearing evaluation. The latter should consist of air and bone audiometry; speech audiometry; Bekesy audiometry, when indicated; and determination of recruitment. If the examiner does not have the equipment to perform these tests, the patient should be referred to a Speech and Hearing center where they may be performed. In general, all patients with unilateral
