Delayed endolymphatic hydrops (DEH) can be clinically classified into ipsi- and contralateral types. This study aims to investigate the relationship between the results of vestibular evoked myogenic potential (VEMP) and caloric testing and the clinical type of DEH.
The data of 33 patients with DEH who underwent both VEMPs and caloric testing were retrospectively examined. The type of DEH was judged from its clinical and audiological course. Theasymmetry ratios of the VEMPs and canal paresis on the caloric test were measured.
The results of VEMP and the caloric testing were consistent with the type of DEH in 61 and 76% of DEH patients, respectively. Combined use of VEMP and caloric testing correctly identified the type of DEH in 82% of patients.
The combined use of VEMP and caloric testing can indicate the type of DEH at a reasonably high rate, but inconclusively.
迟发性内淋巴积水(DEH)在临床上可分为同侧型和对侧型。本研究旨在探讨前庭诱发肌源性电位(VEMP)和冷热试验结果与DEH临床类型之间的关系。
回顾性分析33例接受VEMP和冷热试验的DEH患者的数据。根据其临床和听力学病程判断DEH的类型。测量VEMP的不对称率和冷热试验中的半规管轻瘫。
VEMP和冷热试验结果分别在61%和76%的DEH患者中与DEH类型一致。联合使用VEMP和冷热试验能在82%的患者中正确识别DEH类型。
联合使用VEMP和冷热试验能以较高的概率指出DEH的类型,但不能确定。
