A questionnaire on the clinical use of electrocochleography (ECochG) was distributed to clinics throughout the world which use this method. The 26 replies comprised 3696 cases with a median age of 22.5 years. The majority (57.1%) were tested with a transtympanic promontory electrode. The risk of any undesirable effect from this electrode placement was negligible (less than 0.1%), but a greater probability (less than 1.0%) of serious complication from general anesthetics was revealed. On the benefit side, ECochG added significant information to the diagnoses of 87.8% of the children and 34.2% of the adults, and in 48.2% of the children and 2.0% of the adults this information was a primary factor in the hearing evaluation and decision on management. The cases for which ECochG was most helpful were predominantly children and neonates with complex neurological or psychiatric problems which interfered with reliable testing by other methods. Comparisons of ECochG with other methods were reported in 63.2% of the cases. The respondents judged 97.4% of those comparisons to reflect favorably on the validity of ECochG.
一份关于耳蜗电图（ECochG）临床应用的调查问卷被分发给全球使用该方法的诊所。26份回复涵盖了3696例患者，年龄中位数为22.5岁。大多数（57.1%）患者使用经鼓膜岬电极进行检测。这种电极放置产生任何不良影响的风险可忽略不计（低于0.1%），但全麻导致严重并发症的可能性更高（低于1.0%）。从益处方面来看，耳蜗电图为87.8%的儿童和34.2%的成人的诊断增添了重要信息，在48.2%的儿童和2.0%的成人中，这些信息是听力评估和治疗决策的主要因素。耳蜗电图最有帮助的病例主要是患有复杂神经或精神问题、干扰其他方法进行可靠检测的儿童和新生儿。63.2%的病例报告了耳蜗电图与其他方法的比较。受访者认为其中97.4%的比较结果对耳蜗电图的有效性有利。
