The aim of this study was to compare the treatment outcome following fixation of midface fractures with microplates to that of miniplates.
The prospective study included 30 patients with confirmed diagnosis of midface fractures (Le Fort I, II, III, ZMC fractures or combination) and who gave written informed consent. The patients were categorized into microplate (1.2 mm) group and miniplate (2.0 mm) group with 15 patients in each group using computer-generated randomization. The clinical parameters like occlusion, stability of fixation, chewing efficiency, pain, infection, paresthesia, plate exposure, palpability, aesthetic outcomes and patient's perspective were assessed on postoperative day 1, day 3, after 1 week, 1 month and after 3 months.
There was no statistically significant difference between the two groups in terms of occlusion, stability of fixation, chewing efficiency, pain, infection, paresthesia, plate exposure, aesthetic outcomes and patient's perspective. One patient in microplate group and five patients in miniplate group complained of plate palpability ( = 0.16), suggesting clinically significant difference but statistically no significant difference.
Microplate osteosynthesis gives equivalent results compared to miniplate osteosynthesis, in the fixation of midface fractures in terms of stability and function and clinically superior in terms of aesthetics.
本研究旨在比较使用微型钢板与小型钢板固定面中部骨折后的治疗效果。
这项前瞻性研究纳入了30例确诊为面中部骨折（勒福Ⅰ型、Ⅱ型、Ⅲ型、颧骨-上颌骨复合体骨折或联合骨折）且签署书面知情同意书的患者。采用计算机随机分组法将患者分为微型钢板（1.2毫米）组和小型钢板（2.0毫米）组，每组15例。在术后第1天、第3天、1周后、1个月后和3个月后评估诸如咬合、固定稳定性、咀嚼效率、疼痛、感染、感觉异常、钢板外露、可触及性、美学效果及患者观点等临床参数。
两组在咬合、固定稳定性、咀嚼效率、疼痛、感染、感觉异常、钢板外露、美学效果及患者观点方面无统计学显著差异。微型钢板组有1例患者和小型钢板组有5例患者主诉钢板可触及（P = 0.16），提示有临床显著差异但统计学上无显著差异。
在面中部骨折固定方面，微型钢板接骨术与小型钢板接骨术相比在稳定性和功能上效果相当，在美学方面临床效果更佳。
