The conclusion derived from this study is that the Von Langenbeck palastoplasty as performed on the cleft individuals evaluated here did not produce gross discrepancies in the dento-facial structures or relations examined. On the average, the skeletal and profile relations of the maxilla to the mandible can be considered within the acceptable range. With this in mind, speech becomes a more crucial parameter in evaluating the over-all results of this procedure. Other dental parameters, e.g., incidence of crossbite, arch collapse, etc., need to be examined if a complete evaluation of the results of palatal surgery is described. This should be done after all orthodontic treatment has been completed and all retainers removed.
本研究得出的结论是，在此评估的腭裂患者所接受的冯·朗根贝克腭成形术，在检查的牙颌面结构或关系方面未产生明显差异。平均而言，上颌骨与下颌骨的骨骼及侧貌关系可被认为在可接受范围内。考虑到这一点，语音在评估该手术的整体效果时成为一个更为关键的参数。如果要全面描述腭裂手术的结果评估，还需要检查其他牙齿参数，例如反咬合、牙弓塌陷等发生率。这应在所有正畸治疗完成且所有保持器拆除后进行。
