Acoustic Reflex and Reflex Decay: Occurrence in Patients With Cochlear and Eighth Nerve Lesions

Abstract

• Acoustic reflex and reflex decay tests were administered to 50 normal ears, 50 ears with hearing loss due to noise trauma, 50 ears that had Ménière disease, and 28 ears that had involvement of the eighth nerve. In one normal ear, ten noise trauma ears, 11 Ménière disease ears, and 24 eighth nerve lesion ears no reflexes or reflex decay that were suggestive of retrocochlear lesions were observed. Acoustic reflex and reflex decay results are also compared to tone decay results for these patients. (Arch Otolaryngol 101:622-625, 1975)
