髁状突骨折的治疗是困难的。导致骨折的因素是复杂的。本研究的目的是探讨髁突骨折模式和髁突形态特征之间的关系。我们回顾性分析了107例在华西口腔医院住院的因副骺撞击致双侧髁突骨折的患者。根据髁状突骨折类型将患者分为五组。通过Mimics 16.0（Materialize Leuven，Belgium）人体测量工具包在三维（3D）重建下颌骨模型上评价10个参数。使用多变量分析来分析3D模型的每个参数。多项逻辑回归分析被用来检查五组之间的关系。结果显示：两组髁突头宽（M1）、髁突颈宽（M3）、髁突头宽与髁突前后径之比（M1/M2）、髁突头宽与髁突颈宽之比（M1/M3）、髁突高与升支高之比（M8/M7）、下颌角（M10）差异均有统计学意义（p < 0.05）。A型髁头骨折与M1（与B型相比：OR =1.627，95%CI：1.123，2.359;与C型相比：OR = 1.705，95%CI：1.170，2.484）和M1/M2（与B型相比：OR =1.034，95%CI：0.879，2.484）正相关。B型髁头骨折与M10呈负相关（与C型相比：OR = 0.909，95% CI：0.821，1.007）。髁突颈骨折与M3呈负相关（与髁突头比较：OR = 0.382，CI：0.203，0.720;与髁突基底比较：OR = 0.436，95%CI：0.218，0.874），与M1/M3呈正相关（与髁头相比：OR = 1.229，95% CI：1.063，1.420与髁底相比：OR = 1.223，95% CI：1.034，1.447）。与髁突头骨折相比，髁突基底骨折与M10呈正相关（OR = 1.095，95% CI：1.008，1.189），与M8/M7呈负相关（OR = 0.855，95% CI：0.763，0.959）。髁突骨折模式与髁突的解剖特征相关，当骨折发生于副对称撞击时。
The treatment of the condylar fractures is difficult. Factors that result in the fractures are complex. The objective of this morphometric study was to investigate the relationship between condylar fracture patterns and condylar morphological characteristics. We conducted a retrospective analysis of 107 patients admitted to the West China Hospital of Stomatology for bilateral condylar fractures caused by parasymphyseal impact. The patients were divided into five groups according to the type of condylar fracture. Ten parameters were evaluated on three-dimensional (3D) reconstruction mandible models through the Mimics 16.0 (Materialize Leuven, Belgium) anthropometry toolkit. Each parameter of the 3D models was analyzed using multivariate analysis. Multinomial logistic regression analyses were used to examine the relationships between the five groups. The results showed that the differences of condylar head width (M1), condylar neck width (M3), the ratio of condylar head width to condylar anteroposterior diameter (M1/M2), the ratio of condylar head width to condylar neck width (M1/M3), the ratio of condylar height to ramus height (M8/M7), and mandibular angle (M10) were statistically significant (p < 0.05). Type A condylar head fractures were positively associated with M1 (compared to Type B: OR =1.627, 95% CI: 1.123, 2.359; compared to Type C: OR = 1.705, 95% CI: 1.170, 2.484) and M1/M2 (compared to Type B: OR =1.034, 95% CI: 0.879, 2.484). Type B condylar head fractures were negatively associated with M10 (compared to Type C: OR = 0.909, 95% CI: 0.821, 1.007). Condylar neck fractures were negatively associated with M3 (compared to condylar head: OR = 0.382, CI: 0.203, 0.720; compared to condylar base: OR = 0.436, 95% CI: 0.218, 0.874), and positively associated with M1/M3 (compared to condylar head: OR = 1.229, 95% CI: 1.063, 1.420 compared to condylar base: OR = 1.223, 95% CI: 1.034, 1.447). Condylar base fractures were positively associated with M10 (OR = 1.095, 95% CI: 1.008, 1.189) and negatively associated with M8/M7 (OR = 0.855, 95% CI: 0.763, 0.959) as compared with condylar head fractures. Condylar fracture pattern is associated with the anatomical features of the condyles when a fracture occurs from parasymphyseal impact.
