摘　　要：为配合上颌前移术，探讨了术式有关的应用解剖学。术中上颌骨水平凿线宜在上牙槽突后端最低点之上２０ｍｍ以内，以防伤及上颌动脉或过多侵入上颌窦，如不超过１８ｍｍ，还可不伤及上牙槽后动脉主干。后方纵行凿开线以恰在磨牙之后为好，以防伤及腭大动脉和腭前神经。此外，从摹拟手术的标本上探讨了嵌入支撑骨块的大小等有关的解剖资料。natomic data in forward transposition of maxilla were provided in this study.The hofizon-tal osteotomy line of maxmlla should be limited within 20mm above the lowest posterior extremityof the superior alveolar process to avoid damaging the maxillary artery or extending too much intothe maxillary sinus. Damage to the main stem of superoposterior alveolar arterv could also beavoided by limiting the osteotomy line within 18mm above the lowest point. The longitudinal os-teotomy line of the maxillais should be just behind the molar teeth to avoid damaging the greaterpalatine artery and anterior palatine nerve. The proper size of bone graft transferring to the os-teotomized site was measured as well.
