The healing of Le Fort I maxillary osteotomies was studied histologically in 12 adult rhesus monkeys to determine the effect of split autogenous rib grafts overlaying the osteotomy cuts on the lateral maxillary walls. The maxilla was advanced 8 mm in each animal, and examined at varying intervals up to 24 weeks after surgery. The results indicated that there were no obvious differences between the monkeys with and without the rib grafts. Both groups healed with good osseous union. It is concluded that autogenous rib grafts did not enhance bony healing.
对12只成年恒河猴的Le Fort I型上颌骨截骨术愈合情况进行了组织学研究，以确定自体肋骨移植片覆盖上颌骨外侧壁截骨切口的效果。每只动物的上颌骨均前移8毫米，并在术后长达24周的不同时间间隔进行检查。结果表明，有肋骨移植片和没有肋骨移植片的猴子之间没有明显差异。两组均实现了良好的骨愈合。得出的结论是，自体肋骨移植片并未促进骨愈合。
