摘要
目的对成釉细胞瘤的锥形束CT(CBCT)表现进行总结分析,为其临床诊断提供依据。方法对病理确诊的有完整CBCT影像资料的37例成釉细胞瘤病例进行回顾性分析,观察其不同CBCT表现。结果 37例资料中,31例为原发病例,6例为复发病例。CBCT表现:37例病变中,有36例(97.3%)为骨内型,其中多房型17例,单房型17例,蜂窝型2例;1例(2.7%)为骨外型,即软组织型。88.2%(15/17)多房型病变内见舌形嵴;34例(94.4%)颌骨呈唇颊侧或(和)腭舌侧膨隆,颌骨骨密质局部不连续。结论 CBCT检查能精确地反映成釉细胞瘤病变形态和内部结构,对其术前诊断及手术计划具有重要的指导意义。
Objective To summarize and analyze the cone-beam CT （CBCT） imaging features of ameloblastomas for clinical preoperative diagnosis. Methods Thirty-seven cases with complete data proven by pathology were retrospectively studied for distinct CBCT features. Results Of the 37 cases, 31 were primary and 6 were recurrent. On CBCT images, the 37 cases were composed of 36 cases （97.3%） of intraosseous lesions （17 cases of multilocular lesions, 17 cases of unilocular lesions, and 2 cases of honeycomb lesion） and 1 case （2.7%） of extraosseous lesion （soft tissue lesion）. Of the 17 multilocular cases, 15 （88.2%） showed tongue-shaped crests in lesions. Thirty-four cases （94.4%） showed apparent expansible change toward lip/buccal and （or） palatal/lingual sides of jaw, with partialcortical erosion. Conclusion CBCT imaging yields accurate three-dimensional images of lesion shape and structure. Therefore, CBCT can be usedfor the clinical diagnosis and surgical assessment of ameloblastoma.
