The purpose of this investigation was to evaluate treatment outcomes prospectively when isolated fractures of the mandibular angle are treated by 1) nonrigid fixation that includes 5 to 6 weeks of maxillomandibular fixation, 2) nonrigid but functionally stable fixation using a single miniplate, and 3) rigid fixation using 2 miniplates.
All patients treated for isolated fractures of the mandibular angle at Parkland Hospital over a 12-year period were treated by 1 of the 3 methods sequentially assigned. Demographic, fracture characteristic, and treatment and outcome data were prospectively collected and statistically analyzed to determine whether the 3 treatments produced different outcomes.
One hundred eighty-five patients had sufficient follow-up for inclusion in this study. There were no significant differences in demographic data for the 3 groups. There were significant differences in treatment outcomes for several variables, including the amount of time it took to perform the surgery and postoperative wound problems.
The use of single miniplate was the easiest to perform and was associated with the lowest number of complications.
本研究的目的是前瞻性评估下颌角孤立性骨折采用以下方法治疗时的治疗效果：1）非刚性固定，包括5至6周的颌间固定；2）使用单个微型钢板进行非刚性但功能稳定的固定；3）使用2个微型钢板进行刚性固定。
在12年期间，所有在帕克兰医院接受下颌角孤立性骨折治疗的患者均依次采用上述3种方法之一进行治疗。前瞻性收集人口统计学、骨折特征、治疗及结果数据，并进行统计分析，以确定这3种治疗方法是否产生不同的结果。
185例患者有足够的随访资料纳入本研究。3组患者的人口统计学数据无显著差异。在几个变量的治疗结果方面存在显著差异，包括手术所需时间和术后伤口问题。
使用单个微型钢板操作最简便，且并发症数量最少。
