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.
