The usual methods of measuring the therapeutic effects of middle ear reconstruction in tympanoplasty and stapedectomy take into account only changes occurring in the operated ear. These do not necessarily reflect the final state of the patient's auditory capacity, because normal speech perception is a bilateral function. Minor temporary interaural differences due, for example, to ear canal occlusion by cerumen can cause considerable distress. To determine what might be the final audiometric situations that would be worthwhile for patients having unilateral operations aimed only at improving auditory status, 203 patients' personal assessments of their final hearing ability were correlated with the audiometric data from both ears. The results indicated that the most relevant factor in predicting assessment was the postoperative hearing level.
测量鼓室成形术和镫骨切除术中耳重建治疗效果的常用方法仅考虑手术耳发生的变化。这些变化不一定反映患者听觉能力的最终状态，因为正常的言语感知是双侧功能。例如，由于耵聍堵塞耳道导致的轻微暂时性耳间差异可能会引起相当大的困扰。为了确定对于仅旨在改善听力状况的单侧手术患者来说，哪些最终听力测定情况可能是值得的，将203名患者对其最终听力能力的个人评估与双耳的听力测定数据进行了关联。结果表明，预测评估中最相关的因素是术后听力水平。
