摘要
目的:总结和分析口腔颌面部不同手术中使用钛板出现异常情况的原因并提出相应的预防和处理措施。方法:对28例钛板裸露、螺钉松动或脱落及钛板断裂患者的手术类型、手术时的情况,钛板出现异常情况的时间等进行了回顾性分析与研究。结果:局部软组织张力过大,清创不彻底,钛板所固定的骨段不健康以及操作过程中不规范是钛板出现裸露和螺钉松动的主要原因。手术中反复弯制钛板,钻孔时裂钻紧贴钛板边缘,容易导致术后钛板断裂。结论:钛板放置位置和操作过程应遵循坚固内固定的基本原则,术区软组织避免过度牵拉和损伤,术中尽量减少钛板弯制的次数,在严重污染和继发感染的骨创面应慎用坚固内固定技术。
Objective： To analyze and summarize the complications after titanium-plate used oral and maxillofacial surgeries, and put forward corresponding prevention and treatment strategies. Methods： This retrospective study in- cluded 28 cases with bared titanium plate, loosed or lost screws, or fractured titanium plate. Meanwhile, the type of surgery, situation during the surgery, and time of complications were analyzed. Results.. The bared titanium plate, and loosed or lost screws were mainly caused by the excessive tension of local soft tissue, defective debride- ment, unhealthy bone segments fixed by titanium plate and irregular operation. In addition, bending titanium plate repeatedly, or the crack drill close to titanium plate edge during the surgery could easily lead to the post-operative fracture of titanium plate. Conclusion.. The position and operation process of titanium-plate should follow the basic principles of rigid internal fixation. In titanium plate placed area, soft tissue should not be excessively stretched or damaged. Additionally, it is suggested to reduce the number of bending the titanium plate during the surgery and cautiously use the rigid internal fixation technology in seriously polluted or secondary infected bone wound.
