摘要
目的:评价八种腭成形术的术后腭咽闭合功能。方法:216例腭裂病例采用不同术式行腭裂修复(硬腭延长法、单瓣后退法、双瓣后退法、反向双"Z"法、单侧法等)。测量所有病例手术前后腭长、腭垂至咽后壁距离,术后头颅定位侧位片进行定量分析。结果:(1)不同术式手术前后腭长的变化不同;手术前后腭垂至咽后壁的距离变化不同。(2)经头颅定位侧位片定量分析,不同术式手术后的各指标的测量值不同。手术前后相比硬腭延长法、双瓣后退法、反向双"Z"法对腭部的延长最优,但3者对腭部延长的程度无差异;矢状位的腭咽闭合程度与硬腭长度、发音时软腭的伸长量呈正相关,与软腭的长度无直接相关。结论:较优的术式有硬腭延长法、双瓣后退法、反向双"Z"法。
Objective： To evaluate clinical functions of velopharyngeal clousure resulted from 8 kinds palatoplasty techniques. Methods： 216 patients were treated with different palatoplasty techniques included： extending the hard palate operation, pushback operation, two-flap pushback operation, double-opposing z-plastyoperation, unilateral operation, et at. Lateral cephalometric radiographs were used to evaluate palatal length changes. Results： The palate length differed significantly between different operative techniques. In each case, the distance from uvula to posterior pharyngeal obviously extended after operation comparing with before. Conclusion： （1）Better results of extending the hard palate are methods of two-flap pushback, double-opposing z-plasty techniques. （2）Quantity of velopharyngeal clousure in sagittal plane is positively correlated with the length of hard palate, and the extending length of soft palate in phonation.
