颌面部骨纤维异常增殖症的放射学诊断

Radiologicai Diagnosis of Fibrous Dysplasia of the Facial Bones

目的分析颌面部骨纤维异常增殖症（骨纤）的放射学表现。方法10例颌面部骨纤，均作常规X线检查，部份病例作CT平扫检查，均经手术、病理证实。结果所有病例均示患骨膨隆变形，根据密度改变可分为致密型、磨玻璃型、溶骨型和混合型。哈哈放射学检查能较好诊断颌面部骨料，本病与骨化性纤维瘤的区别在于前者骨膨胀但仍保持其原来外形和病变区边缘不清晰。

Objective To analyze the radiologic findings of fibrous dysplasia of the facial bones. Methods Ten cases all had been studied with routine X - rays examination and part of them with plain CT scan. They were all proved by operation and pathology. Results All cases showed that the involved bone expanded and deformed.According to density changes, the radiologic features might be classified into dense, ground glass, osteolytic and mixed type. Conclusion Radiologic examination can better diagnose this disease. Fibrous dysplasia of the facial bones and ossifying fibroma are two different lesions. The properties of the former are the expanded bone still keeps basically its primitive contour and the border of the diseased area is not clear.
