The study group patients have been treated with 1.6 microplates at the superior border and 2.0 miniplate at the inferior border to evaluate its efficacy in the fixation of symphyseal and parasymphyseal fractures using this technique. The control patients were treated with two 2.0 plates. The stability was assessed using computed tomography immediately performed postoperatively and after 6 months. Assessment of the change in the intercanine distance using the Student T test was statistically Non Significant ( P value 0.34). The change of intercanine distance in the study was 0.04 ± 0.05 mm, compared with that of the control, which was 0.01 ± 0.03 mm. Assessment of change in intermental foramina distance was statistically NS ( P value = 0.06). The average difference in intermental foramina distance in the study was 0.04 ± 0.05 mm, compared with the control, which was 0.002 ± 0.004 mm. Based on the findings of the current study, the authors recommend the use of microplates combined with miniplates in the correction of both symphyseal and parasymphyseal fractures successfully.
研究组患者在上缘使用 1.6 个微型板，下缘使用 2.0 个小型板来评估该技术在固定耻骨联合和耻骨旁骨折中的疗效。对照组患者使用两块 2.0 板治疗。稳定性使用术后即刻和术后 6 个月进行的计算机断层扫描进行评估。使用学生 t 检验评估犬齿间距离的变化在统计学上无显著意义（P 值为 0.34）。研究中犬齿间距离的变化为 0.04±0.05mm，而对照组为 0.01±0.03mm。评估正中切牙孔距离的变化在统计学上无显著意义（P 值=0.06）。研究中正中切牙孔距离的平均差异为 0.04±0.05mm，而对照组为 0.002±0.004mm。基于本研究的结果，作者建议使用微型板结合小型板成功矫正耻骨联合和耻骨旁骨折。
