A New Classification of Zygomatic Fracture Featuring Zygomaticofrontal Suture: Injury Mechanism and a Guide to Treatment
並列摘要
The researchers establish a new classification system for zygomatic fractures based on computed tomography and mechanism of injury, which could be used to inform treatment options. Patients treated for isolated zygomatic fracture at the Keio University Hospital between 2004 and 2011 were recruited for this study. The cases were classified into 4 types based on the fracture pattern of the zygomaticofrontal suture and inferior orbital rim. In total, 113 patients aged 16 to 82 years (mean age (SD) = 39.8 (17.0) years), including 74 men and 39 women, were analyzed. Overall, 54 patients had shear fractures and 59 patients had greenstick type fractures. In both shear and greenstick fractures, the ratio of medial type fractures was significantly higher than that of lateral type fractures (p ＜ 0.001). Furthermore, the number of shear type fractures in those ＜20 years old was lower than that in other age groups (p ＜ 0.05). In conclusion, this classification is an epoch-making classification based on the mechanism of facial injury, and may be used to inform treatment options to achieve optimal biomechanical stability.
