National cross-sectional study.
Tertiary university clinic.
Prevalence of abnormal cVEMP, oVEMP, caloric test, and 6-canal vHIT results on the tumor side and the nontumor side were compared and related to tumor volume with regression analyses in 137 consecutive VS patients assigned to a wait-and-scan protocol in the period 2017 to 2019.
The sensitivity of 6-canal vHIT, caloric test, cVEMP, and oVEMP to detect vestibulopathy in VS patients was 51%, 47%, 39%, and 25%, respectively. Normal tests were found in 21% of the patients. The results of vHIT and caloric test were related to tumor volume, but this was not found for cVEMP and oVEMP.
The caloric test and 6-canal vHIT showed the highest sensitivity in detecting vestibulopathy in untreated VS patients. vHIT, and particularly the posterior canal, was limited with a high prevalence of abnormal results on the nontumor side. A combination of cVEMP and caloric test was favorable in terms of a relatively high sensitivity and low prevalence of abnormal results on the nontumor side. Larger tumors had a higher rate of pathology on caloric testing and vHIT.

方法:大学临床。
方法:异常cVEMP的患病率,oVEMP,热量测试,比较了肿瘤侧和非肿瘤侧的6管vHIT结果,并通过回归分析,对2017年至2019年期间被分配到等待和扫描方案的137例连续VS患者进行了肿瘤体积分析.
结果:6通道vHIT的敏感性,热量测试,cVEMP,在VS患者中检测前庭病变的oVEMP为51%,47%,39%,25%,分别。在21%的患者中发现了正常测试。vHIT和热量测试结果与肿瘤体积有关,但没有发现cVEMP和oVEMP。
结论:在未经治疗的VS患者中,热量测试和6管vHIT在检测前庭病变方面显示出最高的敏感性。vHIT,尤其是后管,在非肿瘤方面异常结果的患病率很高。cVEMP和热量测试的组合在相对较高的敏感性和非肿瘤侧异常结果的低患病率方面是有利的。较大的肿瘤在热量测试和vHIT上具有较高的病理学比率。
