【摘要】：目的探讨颌面部骨岛的临床及影像学特征,分析其发生率、分布规律与年龄、性别及部位的关系。方法对四川大学华西口腔医院放射科患者所拍摄的29 556个全景片做回顾性总结分析。其中男性12 824例,女性16 732例。年龄为8~80岁,平均年龄为23.95岁。结果临床上骨岛无任何症状,X线片表现呈圆形、卵圆形或者不规则形;其大小绝大多数在数毫米到2 cm;以边界清晰、无膨胀的致密硬化区为其特征性表现。29 556个全景片中发现598个骨岛(545例),骨岛发生率为1.84%;49个全景片中发现了2处骨岛,2个全景片发现了3处骨岛。骨岛好发于下颌前磨牙及磨牙根尖区,且无性别差异。结论临床工作中要注意增强对这一变异的认识。
[Abstract]:Objective to investigate the clinical and imaging features of maxillofacial osseous islands and analyze the relationship between the incidence, distribution and age, sex and location. Methods 29 556 panoramic films taken by patients in the Department of Radiology, West China Stomatological Hospital, Sichuan University were retrospectively analyzed. There were 12 824 males and 16 732 females. The average age was 23.95 years. Results there were no clinical symptoms of the bone island. X-ray films showed round, ovoid or irregular shape; most of them were in the order of several millimeters to 2 cm; in size. 598 bone islands (545 cases) were found in 29,556 panoramic films, and the incidence of bone islands was 1.84%. Two bone islands were found in 49 panoramic films, and three bone islands were found in 2 panoramic films. Bone island usually occurs in mandibular premolars and root apex of molars, and there is no gender difference. Conclusion in clinical work, we should pay more attention to enhance the understanding of this mutation.
