【摘要】 目的分析成人分泌性中耳炎的临床听力学特征,探讨年龄、病程与听力改变的相关性。方法选37例(47耳)成人分泌性中耳炎为观察组,选25例(50耳)正常成人为对照组,分别进行纯音测听和声导抗测试检查,并分析比较两组的0.125~8 KHz频率气导听阈、0.25~4 KHz频率骨导听阈、纯音气导听阈均值、纯音骨导听阈均值、气骨导差均值等纯音测听结果,以探讨患者年龄、病程与听阈变化产生的相关性。结果分泌性中耳炎组(观察组)78.72%(37/47耳)为传导性耳聋,21.28%(10/47耳)为混合性耳聋,其各频率气导听阈、0.5~4 KHz各频率骨导听阈、纯音气导听阈均值、纯音骨导听阈均值、气骨导差均值均高于对照组(P<0.01);分泌性中耳炎组年龄与纯音气导听阈均值、纯音骨导听阈均值及气骨导差均值呈正相关(P<0.01),病程与纯音气导听阈均值呈正相关(P<0.05),病程与纯音骨导听阈均值、气骨导差无明显相关(P>0.05)。结论成人分泌性中耳炎除影响中耳传音机能外,对内耳也存在损害,患者年龄是影响分泌性中耳炎的听力状况的重要因素,病程也有一定影响。更多还原

【Abstract】 Objective To investigate the clinical features of secretary otitis media(SOM) in a comparative way with that of SOM group and health adult control group,and analyze the correlation between hearing loss of SOM and age,duration.Methods The 0.125~8 KHz air conduction(AC) audiometry and 0.25~4 KHz bone conduction(BC) audiometry were administered to 37 adult patients(47 ears)with SOM group and 25 control group(50 ears).Then their clinical data,especially that of pure tone audiometry,were analyzed in a comparative way between them.And observed the correlation of the auditory threshold with the age and the duration of patients.Results There were 78.72%(37/47ears) conductive hearing loss,and 21.28%(10/47ears) mixed hearing loss was found in patients.AC threshold in both frequency ranges of SOM group were significant higher than that of control group(P<0.01).BC threshold of SOM group were significant higher than that of control group(P<0.01).Pure-tone average thresholds(PTA) and bone average thresholds and air-bone gap(ABG) of SOM group were significant higher than that of control group(P<0.01).It demonstrates a strong correlation between PTA,bone average thresholds,ABG and the age in SOM group(P<0.01).There was positive correlation between PTA and the duration in SOM group(P<0.05).There were not correlation between ABG and the duration in SOM group(P>0.05).Conclusion The results suggest that SOM in adults may not only affect middle ear mechanics,but also impair inner ear.Age and duration are important influencial factors to auditory of SOM.更多还原
