The mandibular angle is a frequent site of fracture. It is a weak zone that is more exposed to fractures than other areas of the mandibular bone. The presence of incompletely erupted third molars is associated with a further increased risk of angle fractures. Our objective was to evaluate and discuss the surgical outcomes of a group of patients with bilateral mandibular angle fractures.In our study, patients with bilateral mandibular angle fractures surgically treated from January 1, 2001, to June 30, 2009, at the Division of Maxillofacial Surgery of the University of Turin were retrospectively analyzed. A combined transbuccal and intraoral approach or an intraoral approach only was adopted.Eight patients (7 men and 1 woman) underwent surgery for bilateral mandibular angle fractures. Good to satisfactory reduction of the fractures was obtained with both surgical techniques. Good to fair restored occlusion was observed postoperatively in all patients.Successful treatment of bilateral mandibular angle fractures may be achieved via different techniques. Superficially impacted third molars seem to be associated with an increased risk of angle fractures. Bilateral angle fractures are an ideal model to study the biomechanical pathogenesis of angle fractures.
下颌角是骨折的常见部位。它是一个薄弱区域,比下颌骨的其他部位更容易发生骨折。未完全萌出的第三磨牙的存在会进一步增加下颌角骨折的风险。我们的目的是评估和讨论一组双侧下颌角骨折患者的手术效果。
在我们的研究中,对2001年1月1日至2009年6月30日在都灵大学颌面外科接受手术治疗的双侧下颌角骨折患者进行了回顾性分析。采用了经颊和口内联合入路或仅口内入路。
8例患者(7例男性和1例女性)接受了双侧下颌角骨折手术。两种手术技术均使骨折得到了良好至满意的复位。所有患者术后均观察到良好至尚可的咬合恢复。
双侧下颌角骨折可通过不同技术成功治疗。表面受影响的第三磨牙似乎与下颌角骨折风险增加有关。双侧下颌角骨折是研究下颌角骨折生物力学发病机制的理想模型。
