Careful clinical studies and cephalometric and model analyses are required in the planning for treatment of vertical maxillary deficiency. The maxilla is repositioned inferiorly to elongate the face and to achieve facial balance. Simultaneous Le Fort I osteotomy with bone grafting is a helpful adjunct in the treatment of vertical maxillary deficiency in either dentulous or edentulous patients.
在计划治疗垂直性上颌骨发育不足时，需要进行仔细的临床研究以及头影测量和模型分析。将上颌骨向下重新定位以拉长面部并实现面部平衡。对于有牙或无牙患者，同期进行勒福Ⅰ型截骨术并植骨是治疗垂直性上颌骨发育不足的一种有效辅助方法。
