Abstract

Objective: The goal of this project was to report the complications associated with mandibular angle fractures and identify variables affecting their occurrence.

Methods: We retrospectively reviewed the charts of patients with a mandibular angle fracture treated at the Centre hospitalier universitaire de Québec between 2009 and 2013.

Results: Seventy-eight patients (73 males) aged 15-59 years (mean 25.2 years) met our inclusion criteria. A wisdom tooth was present in 85.9% (n = 67) of the cases and it was removed 62.7% (n = 42) of the time. Thirty-four patients (43.6%) had other mandibular fractures. Most fractures were fixated with a sagittal split osteotomy plate (n = 32; 41.0%) or a 2.0-mm plate on the lateral aspect of the mandible (n = 20; 25.6%). The overall complication rate was 42.3% (n = 33); of these 37.2% were infections, 26.9% involved plate removal and 6.4% were associated with non-union. Older patients had more infections (p = 0.03) and more plates removed (p = 0.03). When a wisdom tooth was extracted, more infections (p = 0.04) and overall complications (p = 0.02) were observed.

Conclusion: This study confirms that, when treating a mandibular angle fracture in a healthy patient, it may be beneficial to leave a wisdom tooth in the line of fracture in place, if there is no indication to remove it.

切开复位内固定治疗下颌角骨折的回顾性研究。

目的:本项目的目的是报告与下颌角骨折相关的并发症，并确定影响其发生的变量。方法:回顾性分析2009年至2013年在曲海大学中心医院治疗的下颌角骨折患者的资料。结果:78例患者(73例男性)年龄15-59岁(平均25.2岁)符合我们的纳入标准。85.9% (n = 67)的病例有智齿，62.7% (n = 42)的病例拔除智齿。34例(43.6%)患者有其他下颌骨骨折。大多数骨折采用矢状劈开截骨钢板固定(n = 32;41.0%)或在下颌骨侧面放置2.0 mm钢板(n = 20;25.6%)。总并发症发生率为42.3% (n = 33);其中37.2%为感染，26.9%为钢板取出，6.4%为骨不连。老年患者感染较多(p = 0.03)，取下钢板较多(p = 0.03)。拔除智齿后，感染发生率(p = 0.04)和并发症发生率(p = 0.02)均高于拔除智齿。结论:本研究证实，在治疗健康患者的下颌角骨折时，如果没有指征，在骨折线上保留智齿可能是有益的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
