颌骨骨岛的影像表现分析

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29556个全景片做回顾性总结分析。其中男性12824例，女性16732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2cm；以边界清晰、无膨胀的致密硬化区为其特征性表现。29556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...

Objective To provide reference data on frequency and distribution of bone islands （BIs） and investigate their relationship with age, gender, and localization. Methods A population who received a pretreatment and at least one follow- up panoramic radiograph in the Department of Oral Radiology, West China Hospital of Stomatology, Sichuan University, were selected for this retrospective study. A sample population of 29 556 patients （12 824 males and 16 732 females） with different dental complaints and ages ranging from 8 to 80 years （mean age： 23.95 years） were included. Results In the radio- graphic evaluation, BIs appeared as localized, well-defined, non-expansile, radiopaque masses which were round, elliptic, or irregular in shape. Their sizes varied from a few millimeters to about 2 cm in diameter. A total of 598 radiopacities were detected, and 545 patients of 29 556 patients （1.84%） had BIs. Among subjects with multiple lesions, 49 patients had 2 BIs and 2
