Description
Estimated cost for Le Fort I osteotomy at general public hospitals in China is about ¥12600-28000, and at Grade 3A hospitals about ¥18000-35000, varying by hospital tier and region.
Main Uses
用于矫正上颌骨在三维方向（矢状、垂直、横向）的位置与形态异常，改善咬合功能（如反𬌗、开𬌗、深覆盖）、气道通气（尤其伴OSAHS者）、面部对称性及美学轮廓；适用于经正畸-正颌联合治疗方案确诊的骨性错𬌗畸形患者，需结合CBCT、头影测量及虚拟手术规划实施。
Normal Range
单颌正颌手术（上颌Le Fort I型截骨）并非实验室检验项目，不具传统意义上的‘正常值范围’；其评估依赖于术前影像学测量（如头影测量分析）及三维数字化模拟结果，关键参数包括：SNA角（82°±2°）、SNB角（79°±2°）、ANB角（3°±2°）、上颌平面角（SN-PP，7°±3°）、上颌垂直向高度（面高比，中面部高度/全颜面高度≈0.45–0.50）。术后骨愈合评估指标为CT骨性愈合征象（通常术后6–12周出现连续骨痂、骨小梁桥接、截骨线模糊），无活动性骨吸收或间隙。
