微型钛板坚固内固定技术在下颌骨骨折治疗中的临床应用

A clinical study on treating mandibular fracture by miniplate osteosynthesis

目的 :观察微型钛板坚固内固定技术在下颌骨骨折治疗中的应用效果。方法:对 80例下颌骨骨折病例采用手术复位 ,微型钛板内固定技术治疗。结果 :80例病例均 期愈合 ,无感染 ,4例局部咬合关系欠佳 ,2例有轻度的张口受限。其余咬合关系恢复良好 ,无张口受限 ,固定可靠。 80例 X线检查均未见骨愈合不良或假关节形成。 结论 :微型钛板使用简便 ,固定可靠 ,无需二次手术 ,是一种良好的治疗技术。

Objective: To observe the effectiveness of miniplate osteosynthesis in mandibular fracture. Methods: Mandibular fracture in 80 cases treated with titanium miniplate osteosynthesis was analysed. Results: No infection was found, the mouth opening of 78 cases was satisfactory. The first class difficulty in mouth opening was found in 2 cases 3 months after operation. Conclusion: The miniplate osteosynthesis has the advantages over conventional intermaxillary fixation.
