Since about 10 years a coordinated timing of procedures has been used in Zürich for the management of CLP cases. It equally considers the requirements of growth and functional development. Early orthopedic treatment can, however, only be efficient if concomitant primary surgery is adequately timed and performed. The importance of two-stage palatal closure (soft palate 18 months, hard palate after 5 years of age) is emphasized. In contrast to results of former treatment methods, present cleft patients show good arch form and intermaxillary relationship in deciduous and early mixed dentition. The need for orthodontic treatment is considerably reduced. As far as speech development is concerned, the procedure proves to be beneficial as well.
大约10年来，苏黎世采用了一种协调的手术时间安排来管理唇腭裂病例。它同样考虑了生长和功能发育的需求。然而，早期的骨科治疗只有在同期的一期手术时间安排得当且操作良好的情况下才会有效。强调了两阶段腭裂闭合的重要性（软腭在18个月时，硬腭在5岁以后）。与以前的治疗方法的结果相比，目前的腭裂患者在乳牙列和早期混合牙列中显示出良好的牙弓形态和颌间关系。正畸治疗的需求大大减少。就语音发育而言，该手术也被证明是有益的。
