Evaluate the clinical use of electrocochleography (ECoG) for diagnosis/treatment of Ménière's disease among members of the American Otological Society (AOS) and American Neurotology Society (ANS).
Clinically active members of the AOS/ANS.
Survey responses.
A total of 143 responses were received from 344 possible respondents (41.6%). In suspected cases of Ménière's disease, 45.5% of respondents did not use ECoG at all, 17.5 % used ECoG routinely, and 37.1% used it only in questionable cases. Electrocochleography users differed widely in electrode approach and stimulus modality used, with extratympanic approach and click stimuli used most frequently. Most respondents (73.2%) thought that ECoG is a test of indeterminate value. Only 3.6% required an abnormal ECoG to diagnose endolymphatic hydrops. An abnormal test was a requirement to proceed with ablative therapy for just 8.6% of respondents. Still, 77.9% think that ECoG findings do fluctuate with activity of the disorder, but only 18.0% agree that when the ECoG reverts to normal, one can predict remission of symptoms. Almost half of respondents (46.7%) reported that they have now stopped ordering ECoG due to variability in results and lack of correlation with their patients' symptoms.
Among AOS/ANS members, there is low clinical use of ECoG in diagnosis/management of Ménière's disease. For approximately half of respondents, ECoG has no role in their clinical practice. Electrocochleography was used routinely by only 1 in 6 respondents. Those who used ECoG differed widely in electrode placement and type of stimuli paradigm used.
评估美国耳科学会（AOS）和美国神经耳科学会（ANS）成员在梅尼埃病的诊断/治疗中应用电 Cochleography（ECoG）的临床效果。
AOS/ANS 中有临床活动的成员。
调查回复。
在 344 名可能的受访者中，共收到 143 份回复（41.6%）。在疑似梅尼埃病病例中，45.5%的受访者根本不使用 ECoG，17.5%的人常规使用 ECoG，37.1%仅在可疑病例中使用。使用 ECoG 的患者在电极方法和使用的刺激模式上差异很大，鼓室外方法和点击刺激最常用。大多数受访者（73.2%）认为 ECoG 是一种不确定价值的测试。只有 3.6%的人需要异常的 ECoG 来诊断内淋巴积水。只有 8.6%的受访者要求异常测试作为进行消融治疗的条件。尽管如此，77.9%的人认为 ECoG 结果确实会随疾病活动而波动，但只有 18.0%的人同意当 ECoG 恢复正常时，可以预测症状缓解。近一半的受访者（46.7%）报告说，由于结果的可变性和与患者症状缺乏相关性，他们现在已经停止订购 ECoG。
在 AOS/ANS 成员中，ECoG 在梅尼埃病的诊断/管理中的临床应用率较低。对于大约一半的受访者来说，ECoG 在他们的临床实践中没有作用。只有 1/6 的受访者常规使用 ECoG。那些使用 ECoG 的人在电极放置和使用的刺激模式类型上差异很大。
