In a mixed longitudinal study, dental arch relationships of 88 consecutive UCLP patients treated at the Nijmegen Cleft Palate Centre were evaluated using the Goslon Yardstick. On the basis of timing of hard palate closure, the patients were divided into four groups. Mean age of hard palate closure the patients were divided into four groups. Mean age of hard palate closure in group A (n = 18) was 1.5 years, in group B (n = 26) 4.6 years and in group C (n = 18) 9.4 years. In group D (n = 26, no patient older than 10 years) the hard palate was still open. Four stages of dental development were distinguished; deciduous dentition, early mixed dentition, late mixed dentition and permanent dentition. Reproducibility of scoring with the Goslon Yardstick was good for all stages of dental development. No differences in dental arch relationships were found between the four groups. In 86% of the cases, the dental arch relationships of UCLP patients treated in Nijmegen were acceptable. Pharyngeal flap surgery had minor unfavorable effects on dental arch relationships.
在一项混合纵向研究中，使用戈斯隆标尺对奈梅亨腭裂中心连续治疗的88例单侧完全性唇腭裂患者的牙弓关系进行了评估。根据硬腭闭合时间，将患者分为四组。硬腭闭合的平均年龄：A组（n = 18）为1.5岁，B组（n = 26）为4.6岁，C组（n = 18）为9.4岁。D组（n = 26，无患者年龄超过10岁）硬腭仍未闭合。区分了牙齿发育的四个阶段：乳牙列期、早期混合牙列期、晚期混合牙列期和恒牙列期。戈斯隆标尺评分在牙齿发育的所有阶段的可重复性都很好。四组之间未发现牙弓关系有差异。在86%的病例中，在奈梅亨接受治疗的单侧完全性唇腭裂患者的牙弓关系是可接受的。咽瓣手术对牙弓关系有轻微的不利影响。
