引言晚近对于内耳的神经解剖、生理功能及临床病理,虽有一定的进展和认识,但还有很多方面尚未完全明了,有待于今后进一步研究和阐明。前庭功能试验及其临床病理表现亦不例外。冷热水试验是前庭功能试验中较重要而有价值的一种,它能测定前庭机能变化、自发性眩晕及眼球震颤的病因,鉴别前庭病变是周围性或中枢性,协助中枢病变的定位及小脑桥 INTRODUCTION Although there is some progress and understanding of the neurological anatomy, physiology and clinicopathology of the inner ear recently, there are still many aspects that have not yet been fully understood and yet to be further studied and clarified in the future. Vestibular function test and its clinical and pathological performance is no exception. Hot and cold water test is a more important and valuable test of vestibular function, which can detect changes in the vestibular function, spontaneous dizziness and nystagmus causes, to identify vestibular lesions is peripheral or central, to assist in the localization of central lesions and Cerebellum bridge
