对117例经X线、临床和病理确诊为颌面部骨纤维异常增殖症(FD)中资料齐全的75例的X线征像进行了分析研究。单发性FD占87.2%,多发性占12.8%。X线特征:以毛玻璃型最多见(39例),其次是混合型(24例),囊样型和硬化型少见(各6例)。病变为延伸性随颌骨外形扩张生长,故呈与颌骨外形一致的弥漫性膨大,边界不清,与正常骨无明确分界,牙槽间隔很少受累,牙齿移位少见,根周硬板消失,但牙周膜间隙存在,牙根尖少有吸收,下齿槽神经管多向上移位,骨皮质变薄或消失。此外,还将X线表现结合临床和病理特征作了初步分析。
A total of 117 X-ray images of 75 cases with complete information in maxillofacial fibrous dysplasia (FD) clinically and pathologically confirmed by X-ray were analyzed. Unilateral FD accounted for 87.2%, 12.8% of multiple. X-ray features: the most common type of ground glass (39 cases), followed by the mixed type (24 cases), cyst type and sclerotic rare (6 cases). Lesions as extensibility with the expansion of the jaw shape growth, it was consistent with the shape of the mandible diffuse swelling, the boundary is unclear, there is no clear distinction with the normal bone, alveolar seldom involvement, rare tooth displacement, root week hard Disappear, but the existence of periodontal space, there is little absorption of the root tip, the lower alveolar neural tube upward shift, cortical bone thinning or disappearing. In addition, the X-ray findings combined with clinical and pathological features were initially analyzed.
