egree of hearing loss,thefrequency 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 分泌性中耳炎(secretory otitis media SOM)是耳科的常见疾病,以中耳积液、传导性听力下降为主要特征,并有报道分泌性中耳炎亦可致感音神经性听力损失。本文回顾性研究80例(158耳)以探讨分泌性中耳炎对各频率听力骨导阈值的影响。 1 对象与方法 1.1 研究对象 我科住院患者80例(158耳)分泌性中耳炎患者,其中男44例(87 耳),女36例(71耳),左耳发病80耳,右耳发病78耳,平均年龄8.18岁,平均病程9.79个月。患者均无鼓膜穿孔、无外耳溢液耳病史、耳聋家族史、耳毒性药物史,亦无噪声暴露史的智力发育正常者,查体见鼓膜内陷或鼓室内见液平,鼓室图呈B型或C型甚至异型,鼓室内负压低于150 mmH2O,且鼓膜穿刺或切开抽出液体。 1.2 研究方法上一页 [1] [2] [3] [4] [5] [6] 下一页 |
