Abstract:
OBJECTIVEFor reconstruction of secondary orbit-zygomatic deformities after severe malar fracture.
METHODSWe 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.
RESULTSIn 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.
CONCLUSIONSLamella osteotomy with separated segments movement was benefit to most of secondary deformities in orbito-zygoma displace.
