Fibrous dysplasia (FD) is a fibroosseous lesion of the osseous structures of the body. It is not a commonly reported lesion yet it is considered as an important lesion which can affect the maxillofacial region as well. As a result, it can cause deformity of the jaw bones which can further lead to severe facial asymmetry. Craniofacial fibrous dysplasia (CFD) is one of the subtypes of FD that can affect the bones of the craniofacial complex, including the mandible and maxilla. It can also present as facial asymmetry and can be investigated with the help of Maxillofacial Radiology and Imaging. The radiographic findings may vary according to the extent and degree of the disease. Although conventional radiographs provide a good clue regarding the lesion, advanced maxillofacial imaging is capable of providing detailed extent of the disease. Furthermore the classification of CFD is not very clear in the literature.
This particular paper attempts to document and report the CT appearance of CFD with an attempt to propose a better classification system for the same. Four different patients are reported which presented with FD with involvement of bones of craniofacial region. Working diagnosis of CFD was made with the help of clinical features as well as with radiographic assessment. Advanced imaging included CT scan of the lesions. The article highlights the importance of computed tomography in diagnosis as well as assessment of extent of the disease.
It can be concluded that the Dental professionals must be aware regarding the different radiographic appearances of CFD. Advanced imaging modality like CT can provide with exact diagnosis as well as extent of the lesions like FD. Further collaboration of researchers is required to incorporate this proposed change in classification of CFD.
骨纤维异常增殖症（FD）是一种累及身体骨结构的纤维骨性病变。它并非常见报道的病变，但却是一种可影响颌面区域的重要病变。因此，它可导致颌骨畸形，进而引起严重的面部不对称。颅面骨纤维异常增殖症（CFD）是FD的亚型之一，可累及颅面复合体的骨骼，包括下颌骨和上颌骨。它也可表现为面部不对称，可借助颌面放射学和影像学进行检查。影像学表现可能因疾病的范围和程度而异。虽然传统X线片能提供有关病变的良好线索，但先进的颌面影像学能够提供疾病的详细范围。此外，CFD在文献中的分类并不十分明确。
本文试图记录和报告CFD的CT表现，并尝试为此提出一个更好的分类系统。报告了4例不同的患者，均表现为累及颅面区域骨骼的FD。借助临床特征以及影像学评估做出CFD的初步诊断。先进的影像学检查包括对病变进行CT扫描。本文强调了计算机断层扫描在疾病诊断和范围评估中的重要性。
可以得出结论，牙科专业人员必须了解CFD的不同影像学表现。像CT这样的先进成像方式能够提供准确的诊断以及如FD等病变的范围。需要研究人员进一步合作，将CFD分类的这一建议性改变纳入其中。
