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). Key words: Secretory otitis media; SOM; Child; SNHL
