Abstract

Objectives: To present and discuss the demographic and radiographic aspects of craniomaxillofacial bone islands (BIs) in the population of china. Materials and Methods: A retrospective chart review was performed of all cases of BIs diagnosed in the Department of Oral Radiology in West China College of Stomatology, Sichuan University. The data collected included age at diagnosis, gender, race, location, presenting symptoms, type of BIs. Results: In radiographic evaluation, BIs appear as localized, well-defined, non-expansile, radiopaque masses, which are round, elliptic or irregular in shape and are of variable size, ranging from a few millimetres to about 2 cm in diameter. The results of this study generally supported previous findings that BIs have an overwhelming mandibular predilection, especially, in the pre-molar/molar region, no sex predilection. Conclusions: The presumptive diagnosis of a BI can easily be made if the individual clinical and radiologic findings, together with follow-up examinations, are taken into account. In addition, it is important to recognize this anomaly, evaluate radiographies carefully and distinguish it from other bone variations such as primary or metastatic tumours, which is much more significant clinically in dental examinations.
颅颌面骨岛
目的:介绍和讨论中国人口中颅颌面骨岛(BIs)的人口学和放射学方面的情况。材料与方法:回顾性分析四川大学华西口腔医学院口腔放射科诊断的所有BIs病例。收集的数据包括诊断时的年龄、性别、种族、地点、表现症状、BIs类型。结果:在x线检查中,BIs表现为局部、界限明确、无扩张、不透射线的肿块,形状为圆形、椭圆形或不规则,大小不一,直径从几毫米到约2厘米不等。本研究的结果普遍支持先前的研究结果,即BIs具有压倒性的下颌偏好,特别是在前磨牙/磨牙区域,没有性别偏好。结论:如果考虑到个人临床和放射学表现以及随访检查,可以很容易地做出BI的推定诊断。此外,重要的是要认识到这种异常,仔细评估x线片,并将其与其他骨变异(如原发性或转移性肿瘤)区分开来,这在临床牙科检查中更为重要。
