背景:下颌骨折越来越多的采用口内切开小型钛板张力带内固定治疗,那么微小型钛板在颌骨骨折中起怎样的作用?目的:评价下颌骨骨折骨缺损重建微型钛板坚固内固定的重要性.方法:以 "钛板,下颌骨,骨折,坚固内固定"为关键词.采用计算机检索1995-01/2011-10 PubMed数据库,维普数据库有关坚固内固定技术在下颌骨骨折中的临床应用的文章.排除重复研究,以20篇为重点进行探讨.结果与结论:采用钛板在下颌角上缘张力带内固定辅以颌间固定治疗下颌角骨折,临床操作简单,易掌握,缩短颌间固定的时间,固定稳固性有了可靠的保证,创伤较小,患者能早期张口训练,避免关节强直.有利于内固定后骨折愈合及恢复正常咬合关系.%BACKGROUND: Intraoral incision and mini-plate fixation as tension band have been used to treat for mandibular fracture. The effect of mini-plate has not been fully investigated. OBJECTIVE: To assess the importance of mini-plate fixation during bone defect reconstruction following mandibular fracture. METHODS: With “titanium plate, mandible, fracture, and rigid internal fixation” as key words, a computer-based online search of PubMed and VIP database was performed for articles published between January 1995 and October 2011 related to clinical application of rigid internal fixation in mandibular fracture. Repetitive articles were excluded, and 20 were included and further discussed. RESULTS AND CONCLUSION: Titanium plate has been used as tension band in the superior margin of the mandibular angle, assisted with intermaxillary fixation to treat mandibular angle fracture. This method is simple, convenient, and can shorten duration for intermaxillary fixation, ensuring stability of the fixation. In addition, the incision is minimal, allowing early mouth open training and preventing ankylosis. This method benefits fracture healing and recovery of normal occluding relation following internal fixation.
