作者对18例腭裂术后患者进行鼻咽腔造影,观察其腭咽闭合功能对语音的影响。其中12例用双“Z”型瓣修复术,6例用兰氏两瓣修复。术后0.5～3年鼻咽腔造影检查,结果两组鼻咽腔距离及软腭长度均有显著差异。语音优良率测定双“Z”型瓣术比兰氏两瓣术优良率高。
The authors performed nasopharyngeal angiography on 18 patients with cleft palate and observed the effect of the velopharyngeal closure on speech. Among them, 12 cases were treated with double “Z” type flap repair, and 6 cases were treated with Rankine two flap repair. After 0.5 to 3 years nasopharyngeal angiography, nasal pharyngeal distance between the two groups and soft palate length were significantly different. Voice good rate of determination of double “Z” valve surgery than the two valves excellent rate.
