目的探讨颈前庭诱发肌源性电位（cVEMP）阈值和眼VEMP振幅在诊断上级半规管裂综合征（SCDS）中的敏感性和特异性。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（平均年龄48岁;范围30- 66岁）。cVEMP和oVEMP响应于空气传导声音（ACS）。所有患者均接受手术修复SCDS。cVEMP阈值; oVEMP n10和峰间振幅。cVEMP阈值结果显示诊断SCDS的敏感性和特异性范围为80-100%。相比之下，oVEMP振幅显示灵敏度和特异性> 90%。在SCDS的诊断中，oVEMP振幅上级于cVEMP阈值。
To determine whether cervical vestibular evoked myogenic potential (cVEMP) thresholds or ocular VEMP amplitudes are more sensitive and specific in the diagnosis of superior semicircular canal dehiscence syndrome (SCDS). Prospective case-control study Tertiary referral center 29 patients with SCDS (mean age 48y; range 31–66y) and 25 age-matched controls (mean age 48y; range 30–66y). cVEMP and oVEMP in response to air-conducted sound (ACS). All patients underwent surgery for repair of SCDS. cVEMP thresholds; oVEMP n10 and peak-to-peak amplitudes. cVEMP threshold results showed sensitivity and specificity ranging from 80–100% for the diagnosis of SCDS. In contrast, oVEMP amplitudes demonstrated sensitivity and specificity >90%. oVEMP amplitudes are superior to cVEMP thresholds in the diagnosis of SCDS.
