最常见的上颌骨纤维骨性损害包括纤维异常增殖症、骨纤维瘤、巨型牙釉质瘤,其基本病变为胶原蛋白、成纤维细胞和不定量的骨样组织代替病损区正常骨质,临床表现从不显眼的面部轻度隆起到明显畸形。有些作者认为纤维异常增殖与骨纤维瘤来源相同(Ward等,1969),但多数作者认为两者为各自独立的疾病,其临床表现,X线及病理特点各不相同。本文介绍作者过去10年治疗该病的经验。共20例患者,年龄8～43岁,多为20岁上下,男性居多,其中17例纤维异常增殖症(1例多骨型,16例单骨型),2例牙釉质瘤,1例纤维骨瘤,均经病理确诊。出现症状3个月至17年不等,多长于1年。临床多见一侧面部隆起,同侧龈颊沟消失,眼球突出移位。鼻窦X线相
The most common maxillary fibrous bone lesions include fibroplasia, bone fibromas, and giant enamel tumors. The basic lesions are collagen, fibroblasts, and non-quantitative bone-like tissue instead of normal bone in the lesioned area. The appearance of the face from slight inconspicuous slightly uplifted to obvious deformity. Some authors believe that the abnormal proliferation of fibroblasts is the same as the source of fibrosarcoma (Ward et al., 1969), but most authors consider them to be independent diseases. Their clinical manifestations, X-ray and pathological characteristics are different. This article describes the author’s experience in treating the disease in the past 10 years. A total of 20 patients, aged 8 to 43 years old, mostly 20 years old, males, including 17 cases of fibroplasia (1 case of multiple bone types, 16 cases of single bone type), 2 cases of enamel tumor, 1 case of fiber Osteomas were confirmed by pathology. Symptoms range from 3 months to 17 years and are longer than 1 year. One side of the facial bulge is common in clinic, the ipsilateral cheek groove disappears and the eyeball protrudes. Sinus X-ray
