本文对77例(104耳)慢性化脓性中耳炎病人和20例(40耳)无耳部疾患的青壮年进行骨导听力测试,其结果慢性化脓性中耳炎单纯型组、胆脂瘤-骨疡型组骨导听阈均值t检验明显高于无耳部疾患的青壮年组(P<0.001);但单纯型组、胆脂瘤-骨疡型组骨导听阈均值比较除1000Hz外,其余各频率差异无显著性(P>0.05);慢性化脓性中耳炎病程10年以下组、11年以上组骨导听阈均值比较差异均无显著性(P>0.05);并对慢性化脓性中耳炎患者骨导听阈提高的原因进行了分析讨论。
Bone conduction tests were performed on 77 (104 ears) chronic suppurative otitis media patients and 20 cases (40 ears) of non-ear disease young adults. The results were as follows: Chronic suppurative otitis media simple group, cholesteatoma - The mean t-test of bone conduction threshold was significantly higher than that of young adults without ear disease (P <0.001). However, in the simple type and cholesteatoma-type group, (P> 0.05). There was no significant difference in the mean value of bone conduction threshold between the group of chronic suppurative otitis media for more than 10 years and the group of more than 11 years (P> 0.05), and increased the threshold of bone conduction in patients with chronic suppurative otitis media The reasons for the analysis and discussion.
