This study was carried out to analyze the relationship between clinical factors and velopharyngeal closure (VPC) in cleft palate patients.
Chi-square test was used to compare the postoperative velopharyngeal closure rate. Logistic regression model was used to analyze independent variables associated with velopharyngeal closure.
Difference of postoperative VPC rate in different cleft types, operative ages and surgical techniques was significant (P=0.000). Results of logistic regression analysis suggested that when operative age was beyond deciduous dentition stage, or cleft palate type was complete, or just had undergone a simple palatoplasty without levator veli palatini retropositioning, patients would suffer a higher velopharyngeal insufficiency rate after primary palatal repair.
Cleft type, operative age and surgical technique were the contributing factors influencing VPC rate after primary palatal repair of cleft palate patients.
本研究旨在分析腭裂患者临床因素与腭咽闭合（VPC）之间的关系。
采用卡方检验比较术后腭咽闭合率。使用逻辑回归模型分析与腭咽闭合相关的自变量。
不同腭裂类型、手术年龄和手术技术的术后VPC率差异有统计学意义（P = 0.000）。逻辑回归分析结果表明，当手术年龄超过乳牙列期，或腭裂类型为完全性，或仅接受了未进行腭帆提肌复位的单纯腭裂修复术时，患者在初次腭裂修复术后腭咽功能不全率会更高。
腭裂类型、手术年龄和手术技术是影响腭裂患者初次腭裂修复术后VPC率的因素。
