摘要： 目的:探讨锥形束计算机体层摄影术( CBCT)在下颌骨肿瘤和肿瘤样病变检查中的应用价值。方法:回顾性分析16例经病理证实的下颌骨肿瘤和肿瘤样病变的CBCT资料,包括轴面、冠状面、矢状面、曲面重建图像及VR图像,评价病变的大小、形态、范围、内部结构特征,及其与邻近牙齿、下颌神经管的解剖关系,并与术中所见相比较。结果:13例病变中,牙瘤6例,成釉细胞瘤3例,角化囊性瘤3例,骨化性纤维瘤2例,骨纤维异常增殖症2例,所有病例的形态、范围、内部结构特征,以及与邻近牙齿、下颌神经管的关系显示清楚,与术中所见一致。结论:CBCT扫描能够全面提供下颌骨肿瘤和肿瘤样病变的影像学信息,可作为术前常规检查。

Abstract: Objective: To investigate the clinical value of cone beam compted tomography(CBCT) in the diagnosis of mandibular tumors and tumor-like lesions. Methods: CBCT images from 16 cases who suffered from mandibular tumor or tumor-like lesions were studied,including axial,coronal, sagittal,curved planes and volume rendering images of the lesions.The dimension,shape and internal structure of the lesions were observed, the anatomic relationship between the lesions and closed teeth, mandibular canal were analyzed,and verified during the operation. Results: Of the 16 cases of mandibular tumor and tumor-like lesions, 6 cases were odontoma, 3 cases were ameloblastoma, 3 cases were keratocyst, 2 cases were ossifying fibroma, 2 cases were fibrous dysplasia. The dimension, shape and internal structure of all the lesions and the impact with the closed teeth, mandibular canal were displayed distinctly, there were no different during the operations. Conclusion: CBCT can support completely image information of mandibular tumor and tumor-like lesions and can be a routine examination before operation.
