小型钛板坚强内固定术治疗下颌骨骨折的临床观察

目的：探讨不同固定方法治疗下颌骨骨折的临床效果。方法：回顾性分析2009年1月-2012年12月本科室收治的下颌骨骨折患者150例，采用随机数字方法分为对照组75例和观察组75例，对照组采用小钢板固定法，观察组采用钛板坚强内固定术。评价治疗后口腔功能恢复情况，比较各组固定方法的效果。结果：两组手术时间、住院时间比较差异有统计学意义（t=1.26、P〈0.05；t=6.73，P〈0.05）；两组延迟愈合率比较差异有统计学意义（Х^2=4.83，P〈0.05）；两组并发症发生率比较差异有统计学意义（Х^2=3.17，P〈0.05）。结论：小型钛板坚强固定术具有对患者的美学效果，口腔恢复功能及生物相容性均较小型钢板固定优良，适合下颌骨骨折固定的应用，值得临床推广使用。

Observation of Small Rigid Internal Fixation for Mandibular Fractures

Objective：To investigate the clinical effect of different fixation methods in the treatment of mandibular fracture. Method：150 patients with mandibular fractures were retrospectively analysed in our department from January 2009 to December 2012,and were randomly into two groups, each had 52 cases,the control group with the small steel plate fixation method,the observation group used the titanium plate firm fixation. Evaluated the recoverable function of oral cavity after treatment,compared the effect of different fixation methods. Result：Compared operating time and hospitalizing time of two groups ,the differences were statistical significant（t=1.26,P〈0.05;t=6.73,P〈0.05）;Compared the delayed healing rate,the difference between the two groups was statistically significant（ χ^2=4.83,P〈0.05）. Compared the incidence of complication of two groups,the difference was statistically significant（χ^2=3.17,P〈0.05）.Conclusion：Mini titanium plate firm fixation has the aesthetic effect on patients ,whose recovering function of oral cavity and biocompatibility are better than small steel plate fixation . Therefore,it is suitable for application of mandibular fractures fixed and worthy of clinical use.
