水平半规管BPPV患者复位前后冷热试验临床分析
A Clinical Analysis of Bithermal Caloric Tests before and after the Reduction of Benign Paroxysmal Positional Vertigo Patients with Horizontal Semicircular Canals
摘要
Abstract
Objective To investigate the impacts of the otolith on the vestibular function before and after the repositioning maneuvers in patients with primary horizontal semicircular canal benign paroxysmal positional vertigo(HC-BPPV).Methods The 51 patients visiting our dizziness clinic were diagnosed with primary HC-BPPV from August 2014 to March 2015.All of them completed bithermal caloric tests before the canalith repositioning maneuvers and retests after the repositioning maneuvers to understand the function of vestibular.The canal paresis(CP) values were selected as the prima parameter.It was considered abnormal when the CP value was equal to or greater than 25％.Results There were 36 patients with canal paresis,including 6 patients with ipsilateral canal paresis(CP＞25％) and 30 patients with contralateral canal paresis before the repositioning maneuvers.The incidence of canal paresis on the intact side was higher than the affected side with significant differences,indicating the vestibular excitability on the affected side was stronger than the non-affected side before the repositioning maneuvers.15 patients examined by bithermal caloric tests showing the bilateral vestibular function was roughly symmetrical.All 51 patients showed no canal paresis after the maneuvers,and the difference was statistically significant (P＜0.001).Conclusion The vestibular function of the patients with the canalolithiasis type of HC-BPPV was temporarily and reversibly affected by the otoliths.The otoliths increased the flow inertia of the endolymph;therefore,the stimulation to the crista ampullaris became stronger which may cause the increase of lateral vestibular excitability of the HC-BPPV patients.关键词
