目的 :了解腭裂对中耳传音和咽鼓管功能的影响及其影响的程度。方法 :对 41例腭裂患者进行耳科学常规检查、咽鼓管咽口形态观察、声导抗测试 ,并与听力正常人进行对照。结果 :腭裂患者中鼓膜病变率达 89.0 % ,咽鼓管咽口呈裂隙状形态达 5 9.5 % ,鼓室压图异常达 83.1% ,镫骨肌反射消失率达 84.4% ,与正常人对照 ,有极显著性差异。腭裂患者并发分泌性中耳炎的比率为 74.0 %。结论 :由于腭裂患者存在鼻咽部的易感染性和咽鼓管扩张肌力的薄弱或障碍 ,咽口形态的不良改变 ,从而导致中耳病变及分泌性中耳炎的发病率较正常人显著增高 Objective: To understand the impact of cleft palate on the middle ear sound and Eustachian tube function and the extent of its impact. Methods: A total of 41 patients with cleft palate were examined with routine otology, pharyngeal pharyngeal orifice morphology and acoustic impedance test, and compared with normal hearing subjects. Results: The rate of eardrum edema was 89.0% in patients with cleft palate, the shape of eustachian tube in pharyngeal mucosa was 5 9.5%, the tympanogram was 83.1%, and the disappearance of stapedius reflex was 84.4%. Compared with normal controls, Very significant difference. Cleft palate patients with secretory otitis media was 74.0%. CONCLUSIONS: Due to the presence of nasopharyngeal and nasal pharynx susceptibility and eustachian tube dilatation muscle weakness or disorder, pharyngeal orifice morphology of the adverse changes, resulting in the incidence of otitis media and secretory otitis media was significantly higher than normal
