To determine whether cervical vestibular evoked myogenic potential (cVEMP) thresholds or ocular VEMP (oVEMP) amplitudes are more sensitive and specific in the diagnosis of superior semicircular canal dehiscence syndrome (SCDS).
Prospective case-control study.
Tertiary referral center.
Twenty-nine patients with SCDS (mean age 48 yr; range, 31-66 yr) and 25 age-matched controls (mean age 48 yr; range, 30-66 yr).
INTERVENTION(S): cVEMP and oVEMP in response to air-conducted sound. All patients underwent surgery for repair of SCDS.
MAIN OUTCOME MEASURE(S): cVEMP thresholds; oVEMP n10 and peak-to-peak amplitudes.
cVEMP threshold results showed sensitivity and specificity ranging from 80% to 100% for the diagnosis of SCDS. In contrast, oVEMP amplitudes demonstrated sensitivity and specificity greater than 90%.
oVEMP amplitudes are superior to cVEMP thresholds in the diagnosis of SCDS.
确定颈性前庭诱发肌源性电位（cVEMP）阈值或眼性前庭诱发肌源性电位（oVEMP）振幅在诊断上半规管裂综合征（SCDS）中哪个更敏感和特异。
前瞻性病例对照研究。
三级转诊中心。
29 例 SCDS 患者（平均年龄 48 岁；范围，31-66 岁）和 25 例年龄匹配的对照组（平均年龄 48 岁；范围，30-66 岁）。
空气传导声音刺激下的 cVEMP 和 oVEMP。所有患者均接受 SCDS 修复手术。
cVEMP 阈值；oVEMP n10 和峰峰值振幅。
cVEMP 阈值结果显示，诊断 SCDS 的灵敏度和特异度范围为 80%-100%。相比之下，oVEMP 振幅的灵敏度和特异度均大于 90%。
oVEMP 振幅在诊断 SCDS 方面优于 cVEMP 阈值。
