BACKGROUND/AIM: There are no data available to show whether there is a relationship between mandibular fractures and isolated fractures of the posterior and/or lateral walls of the maxillary sinus. The aim of this study was to determine whether there is a coincidence between these fracture patterns.
Four hundred large volume cone beam computed tomography scans (CBCT) of patients with a fracture of the mandible between 2008 and 2013 were analyzed retrospectively. Patients with multiple midfacial fractures were excluded. The radiographic findings were correlated with epidemiological and clinical data of the patients such as gender, age, treatment methods, or complications.
The most frequent fracture sites of the mandible were the jaw angle, the parasymphysis region, and the condyle. Nineteen of the 400 patients (4.75%) had an isolated fracture of the lateral and/or posterior maxillary sinus. Odds-ratio analysis revealed a high tendency for significant correlation of condylar process fractures with isolated maxillary sinus fractures. Chi-square test demonstrated a P-value near statistical significance (P=.054). No other fracture site of the mandible could be associated with an isolated fracture of the maxillary sinus.
A condylar process fracture of the mandible after trauma without any further injury of the midface may be associated with an isolated fracture of the lateral and/or posterior maxillary sinus.
背景/目的：目前尚无数据表明下颌骨骨折与上颌窦后壁和/或外侧壁孤立性骨折之间是否存在关联。本研究的目的是确定这些骨折类型之间是否存在巧合。
回顾性分析2008年至2013年间400例下颌骨骨折患者的大视野锥形束计算机断层扫描（CBCT）。排除多发性面中部骨折患者。将影像学检查结果与患者的流行病学和临床数据（如性别、年龄、治疗方法或并发症）进行关联分析。
下颌骨最常见的骨折部位是下颌角、颏旁区域和髁突。400例患者中有19例（4.75%）发生了上颌窦外侧壁和/或后壁的孤立性骨折。优势比分析显示髁突骨折与孤立性上颌窦骨折有高度显著相关性倾向。卡方检验显示P值接近统计学显著性（P = 0.054）。下颌骨的其他骨折部位与上颌窦孤立性骨折均无关联。
外伤后下颌骨髁突骨折且面中部无其他损伤可能与上颌窦外侧壁和/或后壁的孤立性骨折有关。
