摘要
目的 改进设计一侧颧骨过小畸形的手术治疗方法 ,使骨组织、软组织总体整复效果有明显提高。方法 采用颧骨推进 +植骨 +颞顶筋膜瓣转移的方法进行整复治疗。全冠或半冠切口 ,颧骨截断整体推进 ,在颧骨后裂缝中植骨 ;或将颧骨劈开为内、外两层骨板 ,在内外骨板间植骨。对伴有颧部软组织发育不良者 ,采用颞浅、颞顶筋膜瓣修复。结果 7例一侧颧骨过小畸形患者按此法手术 ,重塑的颧突达到正常形状 ,与健侧协调。结论 颧骨推进增大法手术 ,恢复了颧突的骨性和软组织外形 ,植骨易于成活 ,为整复颧骨过小畸形提供了一条新的途径。
Objective For the treatment of micro zygomatic bone deformity,the method of the zygomatic bone advancement combined with bone graft and temporalparietofascial flap transfer was used to restore the orginal contour of the zygoma.By this technique,the bone graft was fixed in the gape splitted,so the bone graft was easy to success. Methods The gape left after the push forword and expansion should be measured by the face bow preoperation. Through the bicoronal or coronal incision, the zygomatic bone and the interproximalbones could be exposed.The defect formed after zygoma advancement was repaired by bone graft,or the fissure formed after splitting zygoma frontal process was filled with the bone graft.The pedicled temporalparietofascial flap with the superficial temporal vesseles was used to cover the bone graft and the reconstructed zygomatic bone to make the soft tiussue plentiful.Results 7 cases have been operated by the zygomatic bone advancement. The wounds healed well.The surface of the rebuilding zygomatic bone is natrual and smooth in shape.Conclusion The technique of the zygomatic bone advancement improved the effects of malar augmentation,and provided a new approach for the repair of the developmental and congenital zygomatic bone deformity.
