摘要
对１１７例（１２６耳）慢性化脓性中耳炎病人进行纯音听力测试，就其骨、气导阈值与中耳病变程度进行统计分析，所有参与分析病例均除外其他致聋因素。使用ＩＢＭ－ＰＣ／ＡＴ微机及ＳＰＳＳ／ＰＣ统计软件进行分析。中耳病变程度从单纯鼓膜穿孔→听骨中断、破坏→骨质破坏，分为６个级别。结果发现随中耳病变的加重，低、中、高频骨导听阈呈逐渐上升趋势。资料显示纯音测听出现较明显高频气导听力损失及中、低频骨导听力损失，常预示中耳病变较重。
The correlation between severity of the lesion in tympanum and hearing loss was stud-ied retrospectively on patients with chronic suppuraoive otitis media(CSOM).Based on AC and BC threshold examined before operation and the extent of tympanic lesion observed dur-ing operation from 117 patients(126 ears)with CSOM,it was found that the degree of hearing loss was much more affected by the integrity and functional status of ossicular chain. This study also demonstrated that high frequencies AC,middle and low frequencies BC hearing loss indicated the severity of the rniddle ear diseases and the operation should be performed early to achieve satisfactory hearing results and prevent from complication
