我们记录了12例诊断为同侧迟发性内淋巴积水（DEH）的患者的前庭诱发肌源性电位（VEMPs）。75%（9/12）的患者在患耳中表现出VEMPs减少或缺失。几乎所有的患者在未受影响的耳朵中有正常的VEMP。此外，在4例患者中，在口服甘油（1.3 g/kg体重）之前和之后3 h记录了VEMP。在甘油给药前受影响耳朵VEMPs异常的3例患者中，2例患者的VEMPs在甘油给药后得到改善。甘油给药后，4例患者未受影响耳的VEMP均未出现显著变化。甘油给药后VEMPs的改善证实了同侧DEH患者存在内淋巴积水。结论：VEMPs可用于评价同侧DEH患者耳石器官的功能，VEMPs甘油试验可用于检测同侧DEH患者的内淋巴积水。
We recorded vestibular evoked myogenic potentials (VEMPs) in 12 patients diagnosed as having ipsilateral delayed endolymphatic hydrops (DEH). Seventy-five percent (9/12) of the patients showed decreased or absent VEMPs in the affected ears. Almost all patients had normal VEMPs in the unaffected ears. In addition, in 4 patients, VEMPs were recorded before and 3 h after oral glycerol administration (1.3 g/kg body weight). VEMPs improved after glycerol administration in 2 of the 3 patients whose VEMPs had been abnormal in the affected ears before glycerol administration. None of the 4 patients presented significant changes in VEMPs in the unaffected ears after glycerol administration. Improvement of VEMPs after glycerol administration confirmed the existence of endolymphatic hydrops in patients with ipsilateral DEH. In conclusion, VEMPs are useful to evaluate the function of otolith organs in patients with ipsilateral DEH, and the glycerol test using VEMPs may be useful to detect endolymphatic hydrops in ipsilateral DEH.
