面中份骨折小钛板内固定和钢丝骨间结扎治疗的比较观察

Comparison of internal fixation with mini-titanium plate and wire osteosynthesis in midface fractures

目的比较钢丝骨间结扎和小钛板内固定治疗面中份骨折的临床效果。方法采用头皮冠状入路及辅助切口,对40例面中份骨折行钢丝骨间结扎和小钛板坚固内固定治疗。结果钢丝骨间结扎不能获得良好的稳定性,而小钛板坚固内固定则可重建面中份骨骼的支柱结构,获得足够的三维稳定性和重建理想的面部外形。在眶下缘、颧上颌缝区,手术野显露较差,小钛板内固定较钢丝骨间结扎更为方便可靠。结论小钛板坚固内固定是治疗面中份骨折的最佳方法。

Objective To compare clinical results of the internal fixation with wire and the inter- nal fixation with mini-titanium plate in midface fractures.Methods By the coronal approach and supple- mentary incisions,forty patients with midface fractures were treated with wire osteosynthesis or rigid in- ternal fixation(RIF)with mini-titanium plate.Results A good stability can not he obtained with wire osteosynthesis in the treatment of midface fractures.The supporting bony structure of midface can be re- constructed with mini-titanium plate RIF,which results in a sufficient three-dimensional stability of the fractured segments and an ideal facial configuration Mini-titanium plate RIF is more convenient and reli- able than wire osteosynthesis in the difficult operation fields of the infraorbital margin and zygomaticomax- illary suture.Conclusion Mini-titanium plate RIF is the best method for treatment of midface fractures.
