分泌性中耳炎致儿童骨导听阈下降21例分析

目的探讨分泌性中耳炎（secretory otitis mediaSOM）对儿童骨导阈值的影响。方法回顾性分析80例（158耳）2—16岁分泌性中耳炎患者，并选取38例（53耳）同年龄段听力正常人为对照组，分析SOM导致的听力损失程度、频率特异性以及性别、左右耳侧别、病程长短等因素的影响。结果分泌性中耳炎引起听力损失骨导约在16dBHL左右（其中骨导〉20dBHL者21例39耳，占26％），其损失程度与性别、左右耳侧别以及病程时间长短差异无统计学意义（〈0．05）；各频率阈值之间差异有统计学意义，以高频下降为甚。结论分泌性中耳炎引起患儿听力损失，其听力损失可呈现多种类型，有发展成感音神经性耳聋的可能。

The Analyzing 21 Cases Of Children' s Bone Conduction Threshold With Secretory Otitis Media' s Influence

Objective To explore the change of the children' s bone Conduction hearing threshold with secretory otitis media(SOM). Methods Retrospectively analyzing 80 SOM patients (158ears)whose age from 2 to 16 years old, and chose 38 kids within the same age (53 ears)to contrast the difference:The degree of hearing loss, the frequency specificity and the relevant factors such as gender course etc. Results SOM can cause the children' s hearing loss, the threshold of Bone Conduction weuld be 16 dBHL(he threshold of Bone Conduction ＞ 20 dBHL was 21 cases, about 26%), there is not Statistics differences between the gender, the left or right ear and the course time (P＜ 0. 05). But in the different frequency, the curve of hearing loss was different. Conclusion SOM can cause the children hearing loss, some probably be sensorineural hearing loss(SNHL).
