ENG testing, whether computerized or not, remains the most useful means of assessing the vestibular system. The caloric test provides invaluable site-of-lesion information that objectively documents a peripheral vestibular lesion. Double (bithermal) caloric irrigation of each ear provides a more thorough and wider range test of inner ear function than a single caloric irrigation because the vestibular system is both excited and inhibited, causing responses in opposite directions, which are important in evaluating patients with underlying spontaneous nystagmus. In an age in which economically efficient and clinically effective diagnostic methods are in high demand, ENG testing remains the gold standard of vestibular function tests.
眼震电图(ENG)测试,无论是否采用计算机化,仍然是评估前庭系统最有用的方法。冷热试验提供了极有价值的病变部位信息,能客观记录外周前庭病变。双耳双温(冷热)灌注比单耳冷热灌注能对内耳功能进行更全面、范围更广的测试,因为前庭系统会同时受到兴奋和抑制,产生相反方向的反应,这对于评估存在潜在自发性眼球震颤的患者很重要。在一个对经济高效且临床有效的诊断方法有高度需求的时代,ENG测试仍然是前庭功能测试的金标准。
