摘　　要：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。117 cases with fibrous dysplasia of jaw bones were diagnosed by combined of clinical,radiologic and pathologicmanifestations.Among them,87.2% cases were monostotic and 12.8% cases were polyostotic.The radiologic fea-tures of the 75 cases were classified into four types:glass-ground like(39 cases),sclerotic(6 cases),cystic(6 cases),and mixed type(24 cases).The lesions showed a growth pattern of extending along the jaw bone contour.It tended toblend imperceptibly into adjacent normal bones with no clear border.Movement of the teeth was rare.The alveolarridge between teeth and the peridontal ligament spaces were preserved normal,but the lamina dura usually disappearedin the affected area.The inferior dental nervechannel usually rised upwards and the bone cortex(cortices)werethinned.A preliminary analysis of the relationship among the clinical,radiological and histopathologic manifestationswas presented.
