【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。更多还原

【Abstract】 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 al.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.更多还原
