Abstract

Background: There are very few reports of the clinicopathological features of ossifying fibroma (OF) of the jaws in Enugu, South-east Nigeria. Aims: To study the prevalence and clinicopathological features of OF in Enugu. Patients, Materials and Methods: An eight-year retrospective study of patients with OF of the jaws was carried out in a tertiary hospital in Enugu, Nigeria. The clinical records, radiographs, histopathology reports, and slides of 87 patients with fibrous lesions, archived in the department of oral pathology and oral medicine were identified and examined. The cases diagnosed with OF by histological examination were retrieved and studied. The data were analysed using the descriptive statistics and presented in the form of frequency tables. The test for a statistical association was carried out using the Chi-square statistics. Results: There were 644 orofacial lesions and 13.5% (87) of these were fibro-osseous tumours. OF constituted 8.9% (57) of the orofacial lesions and 65.5% (57) of fibro-osseous tumors. The male-to-female ratio was 1:1.7. The overall mean age at tumour-onset was 24.1 ± 13.1 years, (range: 5–60 years). The age group at which OF occurred most frequently (43.9%) was 11–20 years. The mandible was the most common site of occurrence, 64.9% (37), while the radiographic features were well-circumscribed opacity 24.6% (14), and mixed lucency–opacity, 22.8% (13). Conventional 54 (94.7%) and juvenile-psammamatoid 3 (5.3%) subtypes were identified. Conclusion: OF is the most prevalent fibro-osseous lesion, occurred mostly in the second decade and exhibits a lower mean age of onset in male patients.

颌骨骨化性纤维瘤:埃努古地区57例及国际文献回顾
背景:关于尼日利亚东南部埃努古地区颌骨骨化纤维瘤(of)的临床病理特征报道很少。目的:了解埃努古地区of的患病率及临床病理特点。患者、材料和方法:在尼日利亚埃努古的一家三级医院对颌骨of患者进行了为期8年的回顾性研究。对口腔病理及口腔医学科87例纤维性病变患者的临床记录、x线片、组织病理学报告及载玻片进行分析。回顾性分析经组织学检查诊断为OF的病例。使用描述性统计对数据进行分析,并以频率表的形式呈现。使用卡方统计量进行统计相关性检验。结果:颌面部病变644例,其中纤维性骨肿瘤占13.5%(87例)。OF占口面部病变的8.9%(57例),占纤维骨肿瘤的65.5%(57例)。男女比例为1:7 .7。总体平均肿瘤发病年龄为24.1±13.1岁(范围:5-60岁)。11 ~ 20岁是发生OF的最常见年龄组(43.9%)。下颌骨是最常见的发生部位,64.9%(37例),而x线表现为界限清晰的不透明24.6%(14例)和混合透明-不透明22.8%(13例)。鉴定出常规型54(94.7%)和幼年类sammamatoid 3(5.3%)亚型。结论:OF是最常见的纤维骨性病变,主要发生在第二个十年,男性患者的平均发病年龄较低。
