微型钛板固定整复陈旧性眶底、眶骨骨折伴邻近颅面骨骨折

目的 探讨陈旧性爆裂眶底、眶骨骨折伴邻近颅面骨骨折所致面部畸形，整复后应用微型钛板（microplate）固定的临床疗效。方法 对20例陈旧性眶底、眶骨骨折患者，根据CT扫描和三维成像诊断，重新截骨复位，用微型钛板根据骨折部位和形态，采用跨2～3个骨折线固定，或将钛板越过粉碎骨折部位，呈桥状两端固定。结果 无论眶底眶缘单纯骨折或粉碎性骨折错位愈合，在整复后微型钛板固定，完全修复了颜面畸形，并恢复了眼球运动和咀嚼功能。随访6个月至1年，无1例发生钛板排斥反应或断裂脱落等并发症。结论 微型钛板可以达到眶骨骨折复位后坚强内固定，是目前整复眶骨和颜面部骨折最有效的固定方法之一，并且使用方法简便，容易掌握。

Restitution and fixation of old fractures of orbita and orbital floor with vicinal facial cranium fracture by using titanium microplate

Objective To investigate the clinical curative effect of titanium microplate to repair and fix obsolete cracky orbital fracture. Methods According to the diagnosis of CT scanning and three-dimensional imaging, 20 cases of obsolete orbital fractures were repaired and fixed by using titanium microplate along fracture lines. The microplates were placed according to the part nad shape of fractures. For the part of comminuted fractures, the two ends of fractures were fixed like a bridge. Results After the repair and fixation of titanium microplate, facial deformity became recuperative completely, eye-ball-movement and mastication function were recovered. During 6- 12 months follow-up period, no reject reaction or cracking or dropping of microplate occured. Conclusions The titanium microplate can make orbital fractures rigid and internal fixed, and the procedure is simple and easy mastered. Therefore, it is one of the most effective materials in the repair and fixation of orbital and facial fractures.
