通过对３０例腭裂患者的声阻抗检查，作者分析了５９耳Ｊｅｒｇｅｒ鼓室功能曲线及镫骨肌声反射的分布，发现在腭裂患者中反映中耳病变的Ｂ型曲线占５９．３％，Ｃ型曲线占６．８％，Ａｓ型曲线为１０％，Ａｄ型曲线为６．８％，反映正常中耳功能的Ａ型曲线仅占１６．９％，结果表明腭裂患者中耳病变的发病率高于正常人。６岁以下的发病率又高于６岁以上者（ＰＧ＜０．０５），但Ｊｅｒｇｅｒ鼓室曲线的分布与腭裂类型无关。此外仅有２３．６％的患者能引出镫骨肌声反射，７６．４％的患者镫骨肌声反射阴性，表明有相当部分的腭裂患者存在着不同程度的传音性聋。
By examining the acoustic impedance of 30 patients with cleft palate, the authors analyzed the distributions of the tympanic function curve of 59 Jerk and the acoustic reflection of the stapedius muscle. It was found that the type B curve reflecting middle ear lesions in patients with cleft palate accounted for 59.3% Curve accounted for 6.8%, As-type curve was 10%, Ad-type curve was 6.8%, A-type curve reflects the normal middle ear function only 16.9%, the results show that the incidence of middle ear disease in patients with cleft palate In normal people. The incidence of 6-year-old was higher than that of 6-year-old (PG <0.05), but the distribution of Jerger's tympanic curve was not related to the type of cleft palate. In addition, only 23.6% of patients can lead to the acoustic emission of the stapedius muscle, 76.4% of the patients with stapedius acoustic reflex negative, indicating that there are a considerable number of cleft palate patients with varying degrees of acoustic deafness.
