Compare the sensitivity and specificity of cVEMP (500 Hz), oVEMP (500 Hz and 4 kHz) in the identification of SSCD. A secondary objective was to identify the influence of dehiscence size and location on cVEMP and oVEMP responses. : Individuals with unilateral (n = 16) and bilateral (n = 10) scan confirmed SSCD were assessed using air-conducted cVEMP and oVEMP : For cVEMP, an amplitude cutoff of 286.9 μV or a threshold cutoff of 67.5 dBnHL revealed, respectively, a sensitivity of 75% and 70.6% and a specificity of 69.4% and 100%. For oVEMP (500 Hz), an amplitude cutoff of 10.8 μV or a threshold cutoff of 77.5 dBnHL revealed a sensitivity of 83.33% and a specificity of 87.5% and 80%, respectively. oVEMP (4 kHz), an amplitude cutoff of 3.1 μV, revealed a high specificity of 100% but a low sensitivity of 47.2%. A positive correlation was noted between the length of the SSCD and the cVEMP and oVEMP (500 Hz) thresholds and cVEMP amplitude. : Our results support the use of oVEMP in the identification of SSCD. The presence of oVEMP (500 Hz) with an amplitude higher or equal to 10.8 μV, a threshold lower or equal to 77.5 dBnHL or oVEMP (4 kHz) amplitude of 3.1 μV represents the most useful to identify SSCD.
比较颈肌源性前庭诱发肌源性电位（cVEMP，500Hz）、眼肌源性前庭诱发肌源性电位（oVEMP，500Hz和4kHz）在半规管裂（SSCD）识别中的敏感性和特异性。次要目的是确定裂孔大小和位置对cVEMP和oVEMP反应的影响。对经扫描证实为单侧（n = 16）和双侧（n = 10）SSCD的个体进行气导cVEMP和oVEMP评估。对于cVEMP，振幅截止值为286.9μV或阈值截止值为67.5dBnHL时，敏感性分别为75%和70.6%，特异性分别为69.4%和100%。对于oVEMP（500Hz），振幅截止值为10.8μV或阈值截止值为77.5dBnHL时，敏感性分别为83.33%，特异性分别为87.5%和80%。对于oVEMP（4kHz），振幅截止值为3.1μV时，特异性高达100%，但敏感性低至47.2%。SSCD的长度与cVEMP和oVEMP（500Hz）阈值及cVEMP振幅之间存在正相关。我们的结果支持使用oVEMP来识别SSCD。振幅大于或等于10.8μV、阈值小于或等于77.5dBnHL的oVEMP（500Hz）或振幅为3.1μV的oVEMP（4kHz）对于识别SSCD最有用。
