The hearing data from a sample of 73 children undergoing surgical treatment for chronic otitis media with effusion (OME) were analysed using a modification of the Glasgow Benefit Plot. All the patients had bilateral middle ear effusions confirmed at surgery. Using 20 dB average hearing level as the 'cutoff' point between normal and abnormal hearing, 65 (89 per cent) patients had binaural normal hearing, five (7 per cent) had monaural normal hearing and three (4 per cent) had bilateral hearing loss after surgery. However, 70 patients (96 per cent) were found to benefit from surgery. The cases with persistent hearing loss were re-examined to determine the cause of failure.
采用改良的格拉斯哥效益图对73例接受慢性中耳积液（OME）手术治疗的儿童的听力数据进行了分析。所有患者在手术中均证实有双侧中耳积液。以平均听力水平20分贝作为正常听力与异常听力的“分界点”，65例（89%）患者双耳听力正常，5例（7%）单耳听力正常，3例（4%）术后双侧听力损失。然而，发现70例患者（96%）从手术中获益。对持续听力损失的病例进行了重新检查，以确定失败原因。
