目的：探讨螺旋CT及三维重建在颌骨造釉细胞瘤中的应用价值。方法回顾性分析11例经手术病理证实的颌骨造釉细胞瘤，均行螺旋CT扫描并行三维重建后处理，观察病变的部位、形态、内部结构及邻近结构侵犯等特征。结果11例患者中，5例病灶位于下颌磨牙区、4例位于下颌体部、2例位于上颌骨。多房型6例，其中3例呈肥皂泡状、3例呈蜂窝状。骨性房间隔可完整或不完整。单房型5例。5例有不同程度牙根吸收。11例病灶均可见周围骨质呈膨胀变薄。7例病灶可见囊壁周围骨质缺损，无硬化缘；2例穿破邻近骨皮质形成软组织肿块。1例侵及上颌窦，5例侵及下颌管。6例病灶呈均一囊性密度，4例呈软组织密度，1例术后10年复发病例呈囊实混杂密度。结论螺旋CT三维成像可直观了解病变在三维立体空间的实际大小、形态、位置、内部结构、周围骨质破坏、牙根吸收及周围组织结构的立体解剖关系，对提高造釉细胞瘤的术前诊断正确率有重要价值，为制订手术方案和放疗计划提供了客观依据。
目的：探討螺鏇CT及三維重建在頜骨造釉細胞瘤中的應用價值。方法迴顧性分析11例經手術病理證實的頜骨造釉細胞瘤，均行螺鏇CT掃描併行三維重建後處理，觀察病變的部位、形態、內部結構及鄰近結構侵犯等特徵。結果11例患者中，5例病竈位于下頜磨牙區、4例位于下頜體部、2例位于上頜骨。多房型6例，其中3例呈肥皂泡狀、3例呈蜂窩狀。骨性房間隔可完整或不完整。單房型5例。5例有不同程度牙根吸收。11例病竈均可見週圍骨質呈膨脹變薄。7例病竈可見囊壁週圍骨質缺損，無硬化緣；2例穿破鄰近骨皮質形成軟組織腫塊。1例侵及上頜竇，5例侵及下頜管。6例病竈呈均一囊性密度，4例呈軟組織密度，1例術後10年複髮病例呈囊實混雜密度。結論螺鏇CT三維成像可直觀瞭解病變在三維立體空間的實際大小、形態、位置、內部結構、週圍骨質破壞、牙根吸收及週圍組織結構的立體解剖關繫，對提高造釉細胞瘤的術前診斷正確率有重要價值，為製訂手術方案和放療計劃提供瞭客觀依據。

Objective To evaluate the application value of three-dimensional (3D) spiral CT in ameloblastomas of the jaw. Methods A total of 11 patients with ameloblastomas of the jaw confirmed by opreation and pathology were analyzed retrospectively. The location, shape, inner and adjacent structures, and density of lesions were analyzed. Results Among 11 cases, 5 lesions were located in the mandibular third molar region, 4 in mandibular body, 2 in the upper jaw, 6 lesions were multilocular, with ‘soap bubble’ appearance in 3 and ‘honeycomb’ in 3, 5 lesions were unilocular. The lesions showed destroyed adjacent cortex in 7 cases and formed soft tissue mass in 4 cases. Root resorption of tooth appeared in 5 cases. The adjacent vital structures (such as mandibular canal, maxillary sinus and nasal cavity) were always invaded by the lesions. Conclusion Ameloblastomas of the jaw have characteristic manifestations on CT. 3D spiral CT can show the lesion’s size, shape, location, inner structure, disruption of adjacent cortex, root resorption, and complex anatomic relationship with adjacent tissues, and provide information for preoperative evaluation.
