目的：比较3种不同的2期腭修复方案的牙弓关系。设计：回顾性，横断面。背景：日本的三个腭裂中心（A， B， C）。患者：90例（A: 39例，B: 26例，C: 25例）日本完全性单侧唇腭裂患者。干预措施：在A中，软腭和后半部分硬腭在平均年龄1年7个月时进行修复。B组软腭和硬腭分别关闭，平均年龄分别为1岁6个月和5岁8个月。C组，软腭和硬腭分别在平均年龄1岁和1岁5个月时关闭。主要观察指标：采用5岁儿童（5- y）指数（5名评分者）和Huddart/Bodenham （HB）指数（2名评分者）评估牙弓关系。结果：5-Y和HB评分的内部和内部可靠性显示出实质性或几乎完美的一致性。3个中心间5-Y评分的平均值和分布无显著差异。小段磨牙HB指数平均值C组明显小于A组和B组（P < 0.05）。结论：5岁患者的牙弓关系在硬腭闭合次数和方法上无显著差异。然而，需要进一步分析婴儿唇裂大小作为协变量对更大样本量的可能影响。
Objective: To compare dental arch relationship outcomes following 3 different 2-stage palatal repair protocols. Design: Retrospective, cross sectional. Setting: Three cleft palate centers (A, B, C) in Japan. Patients: Ninety (A: 39, B: 26, C: 25) consecutively treated Japanese patients with complete unilateral cleft lip and palate. Interventions: In A, the soft palate and the posterior half of the hard palate were repaired at a mean age of 1 year 7 months. In B, the soft palate and hard palate were closed separately at a mean age of 1 year 6 months and 5 years 8 months, respectively. In C, the soft palate and hard palate were closed at a mean age of 1 year and 1 year 5 months, respectively. Main Outcome Measures: Dental arch relationships were assessed using the 5-Year-Olds’ (5-Y) index by 5 raters and the Huddart/Bodenham (HB) index by 2 raters. Results: Intra- and inter-rater reliabilities showed substantial or almost perfect agreement for the 5-Y and HB ratings. No significant differences in mean values and distributions of 5-Y scores were found among the 3 centers. The mean HB index scores of molars on the minor segment were significantly smaller in C than those in A and B (P < .05). Conclusions: There were no significant differences in dental arch relationships at 5 years among the times and techniques of hard palate closure. However, further analysis of the possible influence of infant cleft size as a covariable on a larger sample size is needed.
