慢性卡他性中耳炎表现

来源:华人健康网 | 发布时间:2010-11-22 10:06:21 | www.chinesejk.com

  慢性卡他性中耳炎患者由于咽鼓管粘膜因较长时间的充血、水肿,变得增厚或粘连,引起咽鼓管的功能不良。鼓室内由于长期负压,使鼓膜内陷,活动的范围变小,因此出现耳聋、耳鸣症状。

  (1).耳聋:常因反复急性发作,听力时好时坏,渐进加重。初可为传导性,继可为混合性,早期亦可有“自声增强”现象。积液粘稠时,听力不会因为头位的变动而改变。

  (2).耳鸣:耳鸣常使病人甚感苦恼,初可为低音调,晚期可为高音调(如蝉鸣),但无一定规律,有的患者可感觉耳内有闭塞感,按压耳屏后可暂时缓解。
