[目的]探讨重度耳聋儿童颈性前庭诱发肌源性电位(cVEMP)测试的意义.[方法]实验组选择重度耳聋儿童33例54耳,行cVEMP测试,分析cVEMP的引出率和振幅.同时选择正常儿童9例18耳作为对照组.[结果]实验组54耳中,39耳(72%)引出cVEMP反应;对照组18耳(100%)均引出cVEMP反应.实验组与对照组cVEMP振幅间差异无统计学意义(P=0.37).[结论]通过对重度耳聋儿童进行cVEMP测试可评估重度耳聋儿童的前庭功能.
[Objective] To explore the significance of cVEMP in severe deaf children. [Methods] 33 cases (54 ears) with severe deafness were selected in this study. The cVEMP test was used to analyze cVEMP extraction rate and amplitude. Nineteen eighteen ears of normal children were used as the control group. [Results] The cVEMP response was induced in 39 ears (72%) of the 54 ears and the eighteen ears (100%) of the control group. The amplitude of cVEMP between the experimental group and the control group The difference was not statistically significant (P = 0.37). [Conclusions] The vestibular function of children with severe deafness can be assessed by cVEMP test in children with severe deafness.
