The role of low level (Le Fort I) osteotomy of the maxilla alone, or combined with a mandibular procedure, is discussed for the management of maxillary hypoplasia at the supra-apical level which is commonly associated with repaired cleft lip and palate. Osteotomy at this level influences the soft tissue contours of the nasolabial region of the face. The changes in the soft tissue that can be expected and attained are examined. A brief description of operative procedures and fixation techniques is given and the possible causes of relapse considered.
本文讨论了单纯上颌骨低位（勒福Ⅰ型）截骨术或联合下颌手术在治疗上颌骨根尖上水平发育不全中的作用，这种发育不全通常与唇腭裂修复有关。该水平的截骨术会影响面部鼻唇区域的软组织轮廓。文中研究了预期和可实现的软组织变化。简要描述了手术步骤和固定技术，并考虑了复发的可能原因。
