为了查明腭平面是否是评估腭咽闭合水平的有用指标，我们对 61 例腭裂修复患者（单侧唇腭裂 = 腭裂组）和 82 例无腭裂患者（对照组）进行了从幼儿期到青春期的横断面研究，研究了腭咽功能期间腭平面与腭咽接触水平之间的垂直关系。垂直尺寸的测量来自头颅侧位片上的坐标系和界标，并使用学生 t 检验分析测量差异的显着性。随着生长，腭咽接触点相对于腭平面的变化显示出一致的趋势，尽管两组之间存在差异。在对照组中，PPW（腭平面延伸与咽后壁相交的点）维持在与发lal时腭咽接触中点水平没有显着差异的水平，并且维持在与腭咽接触下点水平没有显着差异的水平，然而在裂组中，它维持在略高于发音时腭咽接触上点水平的水平。这些结果表明腭平面可作为评估腭咽闭合水平的指标。
To find out whether the palatal plane is a useful indicator for evaluating the level of velopharyngeal closure, we did a cross-sectional study from early childhood to puberty of the vertical relationship between the palatal plane and the level of velarpharyngeal contact during velopharyngeal functioning in 61 patients with repaired cleft palate (unilateral cleft lip and palate = cleft group) and 82 controls without clefts (control group). Measurements on the vertical dimension were derived from a coordinate sa stem and landmarks on lateral cephalograms, and the significance of differences in measurements was analysed using Student's t-test, Changes in the points of velarpharyngeal contact in relation to the palatal plane with growth showed a consistent tendency though differed between the two groups. In the control group, the PPW (point where palatal plane extension intersects the posterior pharyngeal wall) was maintained at a level that did not differ significantly from the level of midpoint of velarpharyngeal contact during phonation of lal, and was maintained at a level that did not differ significantly from the level of the inferior point of velarpharyngeal contact, In the cleft group, however, it was maintained at a level that was slightly higher than the superior point of velarpharyngeal contact both during phonation of lal and during blowing, These results suggest that the palatal plane is useful as an indicator for evaluating the level of velopharyngeal closure.
