为了阐明参与腭咽闭合的鼻咽结构随着生长的变化，对61例腭咽闭合完全的单侧唇腭裂修复患者（唇腭裂组）和82例无唇腭裂的对照者（对照组）进行了从幼儿期到青春期的横断面研究。鼻咽部面积的测量值由头颅侧位片上的坐标系和标志点导出，并对测量结果进行多因素分析和t检验。对照组中的适当比率（软腭长度与咽部深度的比率）保持在稳定值，表明1.3左右的比率将是维持咽闭合的标准。腭裂组后颌骨垂直位置、咽部深度和软腭长度的生长模式与对照组不同。然而，两组中均存在维持咽闭合的特征性生长。
To clarify the changes with growth of nasopharyngeal structures involved in velopharyngeal closure, a cross-sectional study from early childhood to puberty was carried out in 61 patients with repaired unilateral cleft lip and palate showing complete velopharyngeal closure (cleft group) and 82 controls without clefts (control group). Measurements of the nasopharyngeal area were derived from a coordinate system and landmarks on lateral cephalograms, and results were analysed by multivariate analysis and t test. The adequate ratio (velar length to pharyngeal depth ratio) in the control group was maintained at a stable value, indicating that the ratio around 1.3 would be standard to maintain velopharyngeal closure. The vertical position of posterior maxilla, pharyngeal depth and velar length in the cleft group showed a different pattern of growth from those in the control group. There was, however, characteristic growth in both groups for maintenance of velopharyngeal closure.
