The research aimed at investigating potential correlations between craniofacial morphological measurements and mandibular pericondylar fractures, based on a retrospective study of 380 mandible fractures treated in our department, during 2010 to 2017. Predictors included morphological measurements and features. Primary outcome was presence of pericondylar fracture; 133 pericondylar fractures were found, including subcondylar, condylar neck, and condylar head fractures. Condylar neck fractures showed negative correlations with condylar neck width (5.7 mm versus 6.7 mm sagittaly, and 6.1 mm versus 6.8 mm coronally, respectively). Gonial angle (117.3 degrees versus 128.7), and mandibular length 106.2 mm versus 110.4 mm, respectively) showed negative correlation with all pericondylar fractures. Ramus height correlated positively with pericondylar fractures (53.6 mm versus 51.2 mm, respectively). Thus, our results showed condylar neck width was a predictor for condylar neck fractures. In addition, individuals suffering from pericondylar fractures had significantly smaller gonial angles, longer ramus height, and shorter mandibular length. These morphologic features are characteristic of individuals with decreased anterior facial height. Our results corroborated a previous study we had conducted, which suggested that increased anterior vertical growth correlates with angle fractures.
本研究旨在通过对2010年至2017年期间在我科治疗的380例下颌骨骨折进行回顾性研究，探讨颅面形态测量与下颌髁突周围骨折之间的潜在相关性。预测因素包括形态测量和特征。主要观察指标为髁突周围骨折的存在情况；共发现133例髁突周围骨折，包括髁突下、髁突颈部和髁突头部骨折。髁突颈部骨折与髁突颈部宽度呈负相关（矢状面分别为5.7mm对6.7mm，冠状面分别为6.1mm对6.8mm）。下颌角（分别为117.3度对128.7度）和下颌长度（分别为106.2mm对110.4mm）与所有髁突周围骨折均呈负相关。下颌支高度与髁突周围骨折呈正相关（分别为53.6mm对51.2mm）。因此，我们的结果表明髁突颈部宽度是髁突颈部骨折的一个预测因素。此外，患有髁突周围骨折的个体下颌角明显更小，下颌支高度更长，下颌长度更短。这些形态学特征是面部前高度降低个体的特征。我们的结果证实了我们之前进行的一项研究，该研究表明面部垂直生长增加与角部骨折相关。
