对31例腭裂患者行声阻抗检查,发现中耳病变和咽鼓管功能紊乱发病率较高,异常的鼓室功能曲线占65.57%,有55.67%耳的鼓室压力处于-100mmH_2O 以上,耳镜检查发现鼓膜病理变化为77.42%,声反射引出率占46.77%,年幼组分泌性中耳炎发病率明显高于年长组。随年龄增长,咽鼓管的平衡功能改善,A 型曲线增加。 Acoustic impedance examination of 31 patients with cleft palate found that the incidence of middle ear lesions and eustachian tube dysfunction was higher, the abnormal tympanogram was 65.57%, tympanic pressure was 55.67%, and the otoscopy was found Pathological changes of the tympanic membrane was 77.42%, the acoustic reflex lead rate was 46.77%, the incidence of secretory otitis media in young group was significantly higher than that in the elderly group. With age, Eustachian tube balance function improved, type A curve increased.
