For reconstruction of secondary orbit-zygomatic deformities after severe malar fracture.
We made shaped segments in orbito-zygoma region using lamella osteotomy, rearranged inferior and lateral orbital segment with inner and upper movement, and fixed the zygomatic fragment in new place with lateral and upward movement. Pre and post operative measurements including Hetel measurement and the angle between orbital horizontal level with bilateral tragus linkage(A-OT) have been done.
In our 22 cases list, lateral and inferior orbital segment was moved to upper and inner direction with 8.1 mm in average, while zygomatic fragent was lift 9.2 mm and pushed 1.5 mm in average. In average 6.5 months follow-up, good facial contour were maintained in most of our list and no obvious relapse was occurred.
Lamella osteotomy with separated segments movement was benefit to most of secondary deformities in orbito-zygoma displace.
用于严重颧骨骨折后二期眶颧畸形的重建。
我们采用薄层截骨术在眶颧区域制作塑形骨段，将眶下和外侧骨段向内上方移位重新排列，并将颧骨骨折块向外上方移位固定于新位置。进行了术前和术后测量，包括赫特尔测量以及双侧耳屏连线与眶水平的夹角（A-OT）。
在我们的22例病例中，眶外侧和下侧骨段平均向内上方移位8.1毫米，而颧骨骨折块平均上抬9.2毫米并外推1.5毫米。平均随访6.5个月，大多数病例面部轮廓良好，未出现明显复发。
带骨段移位的薄层截骨术对大多数眶颧移位的二期畸形有益。
