【摘要】：目的研究分泌性中耳炎(SOM)患者与正常人相比,声导抗各值的差异及与纯音听阈的关系。方法回顾分析我科2008年1月~2013年6月收治的120例(162耳)SOM患者的声导抗和纯音测听资料,并将声导抗各项指标、纯音听阈测试结果与正常对照组作比较。将能抽出液体和不能抽出液体者进行上述指标比较。结果 SOM患者声导抗测试鼓室压、声顺值和Grad明显低于正常组,TW明显高于正常组(P0.05),耳道容积差异无统计学意义(P0.05)。能抽出液体和不能抽出液体组,声导抗各指标差异无统计学意义(P0.05)。SOM患者纯音听阈频率分布差异有统计学意义(P0.05)。听力是否出现障碍除TW外,其余指标差异均无统计学意义。结论声导抗测试鼓室压、声顺值、Grad和TW有助于诊断SOM。鼓室压、声顺值、Grad和TW的值的大小不能为鼓室有否积液提供依据。SOM患者有听力下降,以高频听力下降为主,可以通过声导抗中TW指标的大小,估计听力是否受损。
[Abstract]:Objective to study the relationship between acoustic conductance and pure tone threshold in patients with secretory otitis media (SOM) and normal subjects. Methods the data of acoustic impedance and pure tone audiometry in 120 patients with SOM from January 2008 to June 2013 were analyzed retrospectively. The results of acoustic impedance test and pure tone audiometry were compared with those of normal control group. Compare the above indexes between those who can draw liquid and those who can not. Results in SOM patients, the tympanic pressure, sonoconnormal value and Grad were significantly lower than those in the normal group (P 0.05), but there was no significant difference in auditory meatus volume (P 0.05). There was no significant difference in acoustic conductance between the two groups. There was no significant difference in the frequency distribution of pure tone hearing threshold in patients with P0.05 or SOM. There was no significant difference in hearing impairment except TW. Conclusion the acoustic impedance measurement of tympanic pressure, consonant value, Grad and TW is helpful in the diagnosis of SOM. The values of tympanic pressure, consonant value, Grad and TW could not provide evidence for hearing loss in patients with tympanic cavity or not. Hearing loss was mainly found in patients with high frequency hearing loss, and hearing loss could be estimated by the size of TW index in acoustic impedance.
