小型钛板坚固内固定技术在颌骨骨折中的临床应用

The clinical use of miniplate osteosynthesis of jaw

目的：本文通过对一组颌骨骨折病例的研究，评价了小型钛板坚固内固定技术的可靠性及术后效果。方法：37例患者55处颌骨骨折行小型钛板坚固内固定。结果：37例患者术后伤口均无感染，Ⅰ期愈合：35例恢复术前咬合关系，仅2例出现局部咬合不良。术后开口度≥37mm者34例。结论：颌骨骨折的小型钛板坚固内固定技术固定效果可靠，避免了颌间结扎；对颞下颌关节功能影响小；口内手术入路避免了口外法复位而造成面部皮肤瘢痕形成；较传统的颌骨骨折颌间结扎固定及钢丝拴扎固定有明显优点。

Objective: According to the case of jaw fracture. This article evaluate the reliability and effectiveness of miniplate osteosynthesis in jaw fractures. Methods: 55 jaw fractures in 37 cases treated with titanium miniplate osteosynthesis was analysed. Results: No infection was found in 37 cases, 35 cases had satisfied occlusion, 2 cases had unfavourable local. malocculation. The mouth openning of 34 cases were over 37mm. Only 2 cases under 37mm. Conclusions: The miniplate osteosynthesis, has the advantages over conventional intermaxillary fixation and wire fixation.
