Microfixation and wire fixation techniques were used in combination with miniplates in the stabilization of simulated simple zygoma fractures in four fresh human cadaver heads. An orthogonal conveyer and rigid steel test frame were used to test rotational stability after deforming forces were applied. After testing multiple combinations at an initial deforming force of 5 kg, selected combinations were tested over a range of 2 to 22 kg. Evaluation of force-displacement data revealed that three-point fixation with miniplates was superior to all other methods, in agreement with previous studies. The combination of lateral buttress miniplate fixation in conjunction with microfixation at the zygomaticofrontal and infraorbital rim regions exhibited stable characteristics over the range of forces applied. Miniplate-microplate combinations exhibited greater stability than corresponding miniplate-wire combinations. The combination of miniplate-microplate fixation clinically allows a balance between stability and aesthetics in selected zygoma fractures.
在四个新鲜人类尸体头部模拟简单颧骨骨折的固定中，采用了微固定和钢丝固定技术并结合微型钢板。在施加变形力后，使用正交输送机和刚性钢测试框架来测试旋转稳定性。在初始变形力为5千克时测试了多种组合后，对选定的组合在2至22千克的范围内进行了测试。力-位移数据评估显示，微型钢板三点固定优于所有其他方法，这与先前的研究一致。在颧骨额突和眶下缘区域采用外侧支撑微型钢板固定并结合微固定的组合，在施加的力范围内表现出稳定特性。微型钢板-微型钢板组合比相应的微型钢板-钢丝组合表现出更大的稳定性。微型钢板-微型钢板固定的组合在临床上能够在选定的颧骨骨折中实现稳定性和美观之间的平衡。
