In this study, sagittal facial growth of bilateral cleft lip and palate (BCLP) patients between 6 and 20 years of age is analyzed. The data of Nijmegen were derived from 131 lateral cephalograms taken in 21 BCLP patients who were treated in the Cleft Lip and Palate Center of the University Hospital of Nijmegen. Reported data of 90 BCLP patients treated at the Center of Oslo were used as a reference for comparison. Results of this investigation showed mandibular growth to be similar in both centers. In the premaxillary region some differences were found: The Nijmegen patients presented a more protrusive premaxilla than those at Oslo. The upper front teeth and hence, the premaxilla, were more retroclined in the Nijmegen sample. There were also statistically significant differences in the soft tissue profile. The mean z-score was positive for the nasolabial angle and negative for the angle N'-Sn-Pg'. At 18 years of age, these differences are still apparent. In comparison with Broadbent's values of normal individuals, the SNPg-angle was smaller and the mandibular angle greater in Nijmegen and Oslo. The profiles of the BCLP patients are more convex in Nijmegen and more concave in Oslo than in the noncleft group. Finally, the different treatment strategies of the Cleft Lip and Palate Centers of Nijmegen and Oslo are compared and discussed in terms of their long-term results.
在本研究中，分析了6至20岁双侧唇腭裂（BCLP）患者的矢状面面部生长情况。奈梅亨的数据来自于在奈梅亨大学医院唇腭裂中心接受治疗的21例BCLP患者所拍摄的131张头颅侧位片。奥斯陆中心治疗的90例BCLP患者的报告数据用作比较参考。本研究结果显示，两个中心的下颌生长情况相似。在前上颌区域发现了一些差异：奈梅亨的患者比奥斯陆的患者前上颌更突出。在奈梅亨的样本中，上前牙以及因此前上颌更向后倾斜。软组织侧貌也存在统计学上的显著差异。鼻唇角的平均z值为正，而角N'-Sn-Pg'的平均z值为负。在18岁时，这些差异仍然明显。与布罗德本特的正常个体值相比，奈梅亨和奥斯陆的SNPg角较小，下颌角较大。与非腭裂组相比，奈梅亨的BCLP患者侧貌更凸，奥斯陆的更凹。最后，就长期结果而言，对奈梅亨和奥斯陆唇腭裂中心不同的治疗策略进行了比较和讨论。
