下颌下腺阳性结石的锥形束CT诊断

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〈0.000 1）。结论 CBCT对...

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 loca
