在唇腭裂患者的协调管理中，早期上颌骨矫形治疗是必不可少的，以满足功能要求，而手术干预是推迟，以尽量减少后续的生长干扰，创造最佳条件，为上颌骨节段发展其整个生长潜力，保持或改善拱形和控制手术唇关闭的效果。所用矫形器为软硬复合丙烯酸树脂板。唇手术在6个月左右进行。年龄，18个月时闭合软腭。硬腭在上颌骨前弓发育完成之前是不受影响的，硬腭闭合的时间取决于语言能力和牙齿发育。尽管出生时牙弓的大小和宽度变化很大，但由于相当大的生长速度，牙弓形状的正常化发生在生命的前1年半内，这与正常人相似。在5岁的年龄水平，后牙龈宽度和牙槽嵴长度的中位数接近的非裂隙样本。语言发育不受2期腭闭合的影响。
In the coordinated management of cleft lip and palate patients early maxillary orthopedic treatment is indispensable in order to meet functional requirements while surgical intervention is postponed in order to minimize subsequent growth disturbance, create optimal conditions for the maxillary segments to develop their entire growth potential, maintain or improve arch form and control effects of surgical lip closure. The orthopedic appliance used is a plate of compound soft and hard arcylic resin. Lip surgery is performed at about 6 mo. of age, velar at closure at 18 mo. The hard palate is left untouched up to an age when growth of the anterior maxillary arch is practically completed, timing of hard palate closure depending on speech proficiency as well as on dental development. In spite of a wide variation of arch size and width at birth, normalization of arch form occurs within the first 1 1/2 yr of life, due to the considerable growth rate, which is similar to that in normals. At the 5 yr age level, the median values of post-gingival width and alveolar crest length closely approximate those of a non-cleft sample. Speech development is not relevantly impaired by 2-stage palatal closure.
