目的：研究下颌下腺结石在锥形束CT（CBCT）影像上的特征。方法收集84例下颌下腺结石患者的临床基本资料，包括年龄与性别，以及CBCT影像资料，记录影像资料中结石的数目、形态、大小，以及位置情况，再进一步行统计分析。结果84例患者共计有阳性结石128个，22例患者（占26.19%）具有多发结石；结石形态可分为点状、类圆形、椭圆形、长条形以及不规则形，其中椭圆形最多；结石大小与其水平位置相关，越靠后的结石，其大小具有增大的趋势；发生在导管前段的结石有50个（占39.06%），发生在导管后段的结石有78个（占60.94%），结石水平位置与垂直位置间存在相关性（P<0.0001）。结论CBCT对下颌下腺结石各项特征的评估，以及辅助临床诊断和制定治疗计划具有重要的价值。

Objective To investigate the radiographic features of submandibular sialiths in cone beam CT (CBCT) images. Methods Eighty-four patients with submandibular radiopaque sialiths were included in this study. The clinical features of gender and age and the radiographic features on CBCT, including the number, morphology, size, and location, were recorded for further statistical analysis. Results A total of 128 sialiths were detected from the 84 subjects; 22 subjects (26.19%) had multiple sialiths. The morphology of the sialiths was classified into five types: spot, round, spheroid, elongated, and irregular shapes. Among these types, the spheroid shape was the most frequently detected. A correlation was observed between the size of the sialiths and their location, with the large sialith located at the posterior portion of the duct. About 39.06% (50/128) of sialiths was located at the anterior portion of the duct, and 60.94% (78/128) was located at the posterior portion. The horizon-tal position of the sialith was significantly correlated with its vertical position (P<0.000 1). Conclusion The CBCT images showed important data for the evaluation, diagnosis, and treatment plan of the submandibular sialolithiasis.
