椎基底动脉供血不足（VBI）的听力障碍的发生率被认为比前庭障碍要少得多，但尚未发表VBI患者的常规听力测试结果。为了确定VBI相关耳聋的发生率和主要涉及耳聋的部位，我们研究了70例VBI眩晕患者，使用常规听力学检查和磁共振成像（MRI）。MRI检测到一名患者的耳蜗核的腔隙性梗死，但其他患者的腔隙性梗死不涉及中央听觉结构。25例患者在眩晕发作期间出现耳鸣、耳聋或两者兼有。听力学检查证实15例（21%）患者发生单侧耳聋，其中14例累及耳蜗，1例累及耳蜗核。这些研究结果表明，听力损失发生在大约五分之一的VBI患者，远低于前庭障碍，与VBI相关的耳聋主要涉及耳蜗。(C)2001 Elsevier Science B.V.保留所有权利。
The incidence of auditory disturbances in vertebrobasilar insufficiency (VBI) is considered much rarer than vestibular disturbances, but no routine audiometric test results for VBI patients have been published. To determine the incidence of deafness associated with VBI and the sites predominantly involved in deafness, we studied 70 vertiginous patients with VBI using a routine audiological examination and magnetic resonance imaging (MRI). MRI detected a lacunar infarct involving the cochlear nuclei in one patient, but lacunas did not involve central auditory structures in the other patients. Twenty-five patients experienced tinnitus, deafness, or both, during vertigo episodes. Audiological examinations confirmed the development of unilateral deafness in 15 (21%) patients, involving the cochlea in 14 and cochlear nuclei in one. These findings indicate that hearing loss occurs in approximately one-fifth of VBI patients, much less frequently than vestibular disturbances, and that deafness associated with VBI mainly involves the cochlea.
