摘要
目的研究自体下颌骨外板移植在颅颌面骨骼畸形或缺损修复中的应用。方法经口内切口显露下颌升支下份、下颌角、下颌体 ,根据所需骨量的大小及形状 ,采取一侧或双侧下颌外板 ,经裁剪塑形后配合坚强内固定技术用于颅颌面充填植骨或骨骼支架的重建。结果自 1993年 4月至 1999年 10月共采用下颌骨外板治疗颅颌面骨组织缺损或畸形 5 6例。其中颅颌面先天畸形 15例 ,创伤后畸形修复 2 1例 ,肿瘤切除后重建 3例 ,美容整形 17例。随访 6个月至 3年 ,移植骨与邻近骨愈合良好 ,骨质无明显吸收 ,所有患者面部形态均得到明显改善。结论自体下颌骨外板主要是密质骨 ,移植后很少吸收 ,适合于面部骨骼的充填植骨 ,具有较高的机械强度 ,配合小夹板坚强内固定技术可很好的完成面部支架的重建 ,有效地矫正各种原因导致的颅颌面部骨骼畸形 ,采取方便 ,手术创伤小 ,于体表不遗留瘢痕 ,对生理功能干扰小 ,是理想的自体骨移植材料之一。
Objective To study the autogenous outer mandibular table as a bone graft in the management of craniomaxillofacial deformities. Methods The outer mandibular table was harvested through oral approach, assisted with internal rigid fixation technique, the outer table was used to reconstruct facial bone framework or as onlay bone graft for facial augmentation. Results From April 1993 to October 1999, 56 cases of craniomaxillofacial deformities or bone defects were repaired with outer mandibular table bone graft, including congenital abnormalities(15 cases), post-traumatic deformites(21 cases), bone reconstruction after tumor resection 3 cases and cosmetic plasty(17 cases). The follow-up period ranged from 6 months to 3 years, the grafted bone healed well with the ajascent bones, No obvious bone resorption was observed, the facial apperance were greatly improved. Conclusion The outer mandibular table was composed mainly of dense cortex bone and possesses superior machanical quality, It can be used either as onlay bone graft for regional augmentation or as pillor material for facial fram work reconstruction.
