A radiologic examination is required in the treatment of nasal bone fracture to determine the fracture condition. Thus, there is an increasing need for radiologic classification of nasal bone fractures that can be applied to clinical practice.
Computed tomography was performed in 125 patients with nasal bone fractures to determine which axial view best showed the entire nasal view. The obtained axial view was then used as a reference for classification. The length from the top to the base of the nasal bone was divided into upper, middle, and lower levels, after which the fracture location was determined. If the fracture spanned the boundaries of these levels, it was classified as the total level. Subsequently, the fracture was subclassified based on the fracture direction and pattern and the concurrent fracture.
Radiologic examination of patients with nasal bone fracture showed that nasal bone fracture was frequently found at the total, middle, upper, and lower levels, in that order. Nasal bone fractures at the upper level showed lower frequencies of complication and reoperation than the fractures at the other levels, whereas nasal bone fractures at the total level showed the highest frequencies of complication and reoperation.
Radiologic classification can be useful for preoperative and postoperative evaluations of nasal bone fractures and can be helpful in understanding such fractures because it can efficiently predict the prognosis of a fracture.
鼻骨骨折治疗中需要进行放射学检查以确定骨折情况。因此，越来越需要一种可应用于临床实践的鼻骨骨折放射学分类方法。
对125例鼻骨骨折患者进行计算机断层扫描，以确定哪种轴位视图能最佳显示整个鼻骨视图。然后将获得的轴位视图用作分类参考。将鼻骨从顶部到底部的长度分为上、中、下三层，之后确定骨折位置。如果骨折跨越这些层的边界，则分类为全层骨折。随后，根据骨折方向、形态及合并骨折情况对骨折进行亚分类。
鼻骨骨折患者的放射学检查显示，鼻骨骨折常见于全层、中层、上层和下层，依次递减。上层鼻骨骨折的并发症和再次手术发生率低于其他层的骨折，而全层鼻骨骨折的并发症和再次手术发生率最高。
放射学分类有助于鼻骨骨折的术前和术后评估，有助于了解此类骨折，因为它能有效预测骨折预后。
