梅尼埃病急性眩晕发作期眼震方向的变化及其病理生理学意义一直存在着很多争议。本文作者用ENG描记了两例梅尼埃病人急性眩晕发作从开始到恢复期眼震方向的变化过程。此两例病人均有典型的梅尼埃病史,一例在进行神经耳科学检查时突然眩晕发作,立即用Frenzel氏镜观察,有快相向患耳的Ⅲ度水平旋转眼震,随后用ENG记录,眼震共持续25分钟,以后眼震方向转向健耳,持续20分钟后逐渐减弱消失。另一例在ENG检查冷热试验两次灌水间隔期眩晕突然发作,即用ENG描记,眼震快相向患耳侧,持续20秒钟后改变向健耳
Much controversy exists in the change of nystagmus direction and the pathophysiological significance of Meniere’s disease in acute vertigo attack. The authors used ENG to characterize the course of nystagmus in two Meniere’s patients with acute vertigo onset from onset to convalescence. The two patients had a typical history of Meniere’s disease. One patient had a sudden onset of vertigo during neurosurgical examination. Immediate observation with a Frenzel’s eyeglass showed rapid rotation of the nystagmus to the third degree of the affected ear followed by an ENG recording. Nystagmus a total of 25 minutes after the direction of nystagmus toward the ear, after 20 minutes gradually weakened disappear. Another example in the hot and cold test ENG two occasions irrigation interval dizziness sudden attack, that is, using ENG tracing, fast nystagmus suffering from the ear, after 20 seconds to change to the ear
