感音神经性聋病因复杂,包括脉管系统在内,可由微循环机能障碍或大血管性病变引起,后者指血管异常在迷路动脉近端或不用显微镜即能看见。本文列举三例大血管性感音性聋的原因为大脑前下动脉动脉瘤、椎基底动脉长形扩张和动静脉变形,一旦大血管性病变确定并予以治疗,听力可望改善。小脑前下动脉瘤较少见,临床表现与听神经瘤极为相似,起自小脑前下动脉的动脉瘤非常靠近内听道和Ⅶ、Ⅷ颅神经,最多见的症状为一侧性头痛、面瘫、听力减退和头晕,颅神经功能受累起源 The underlying causes of sensorineural deafness include the vasculature, which may be caused by microcirculation dysfunction or macrovascular disease, and the latter refers to vascular anomalies visible proximal to the lost artery or without a microscope. This article enumerates three cases of vascular deafness due to the reasons for anterior cerebral artery aneurysm, vertebrobasilar artery dilation and arteriovenous deformation, once identified and treated for large vascular lesions, hearing is expected to improve. Anterior inferior cerebellar aneurysms are rare, clinical manifestations and acoustic neuroma are very similar, from the anterior inferior cerebellar artery aneurysm very close to the internal auditory canal and Ⅶ, Ⅷ cranial nerve, the most common symptoms of lateral headache, facial paralysis, Hearing loss and dizziness, origin of cranial nerve involvement
