通过对猴下颌升支矢状骨劈开前徙术后3、6、12和24周时骨段连接区的X线和光镜组织学研究发现，术后的骨愈合过程以次级愈合为主。术后第6周可获得相对稳定的骨连接。在达到充分减张的前提下，尽可能保留升支内外侧肌附丽，有利于提供充足血供和促进骨愈合。下颌升支矢状劈开前徙术有充足的骨创界面，是矫治颌骨畸形的一种理想手术。
By X-ray and light microscopy histological study of the ligament junctional area at 3, 6, 12 and 24 weeks after the sagittal bone ramification of the mandibular ascending branch of the monkey, it was found that the secondary healing . 6 weeks after surgery to obtain a relatively stable bone connection. In achieving the full reduction of the premise, as much as possible to retain the medial and lateral ascending Li attached, is conducive to providing adequate blood supply and promote bone healing. Mandibular ascending branch sagittal split before migration has ample bone interface, is an ideal operation for the treatment of jaw deformity.
