对30例腭裂患者共60耳行声阻抗检查,发现中耳病变和咽鼓管功能障碍发病率较高,占88.3%(53/60)。其中以渗出性中耳炎最常见占55%(33/60),鼓室负压高于100mmH_2O 者占41.7%(25/60)。腭裂的类型与中耳炎及咽鼓管障碍的发生无显著性差异(P>0.05)。年幼组渗出性中耳炎发病率明显高于年长组,年长组则以鼓室负压多见(P<0.05)。声反射消失38耳(63.3%),提示腭裂患者大多伴有不同程度的听力障碍。
A total of 60 ear acoustical impedance tests were performed on 30 patients with cleft palate. The incidence of middle ear lesions and eustachian tube dysfunction was high, accounting for 88.3% (53/60). The most common exudative otitis media accounted for 55% (33/60), tympanic negative pressure was higher than 100mmH_2O accounted for 41.7% (25/60). The type of cleft palate had no significant difference with the occurrence of otitis media and eustachian tube disorder (P> 0.05). The incidence of exudative otitis media in young group was significantly higher than that of the elderly group, while that in the older group was more common (P <0.05). Acoustic reflections disappeared 38 ears (63.3%), suggesting that most patients with cleft palate with varying degrees of hearing impairment.
