Abstract

OBJECTIVES

To compare the performance of ultrasonography with magnetic resonance imaging (MRI) and computed tomography (CT) for detecting submandibular sialoliths.

METHODS

Thirteen patients with suspected submandibular sialoliths who underwent ultrasonography and CT or MRI were included. Sialoliths were diagnosed using CT (11 cases) or MRI (two cases). The submandibular duct was classified into distal and proximal ducts based on the point around the mylohyoid muscle. Sialoliths located in the proximal duct were difficult to differentiate from those located within the submandibular gland (SMG). Therefore, the location of the sialoliths was classified as follows: within the SMG/proximal duct and within the distal duct. The ultrasound results were compared with CT/MRI results.

RESULTS

Of the 13 patients included, two had sialoliths in both the SMG/proximal duct and the distal duct, three had sialoliths in the SMG/proximal duct, and five had sialoliths in the distal duct on CT or MRI. In this small cohort, all five sialoliths in the SMG/proximal duct were detected by ultrasoonography; however, of the seven cases with sialoliths located in the distal duct, only three could be detected by ultrasonography.

CONCLUSIONS

The incidence of sialoliths in the distal duct was higher than that in the SMG/proximal duct. Ultrasonography showed a good performance compared with CT/MRI in the SMG/proximal duct but not in the distal duct.

摘要

目的

比较超声检查与磁共振成像(MRI)及计算机断层扫描(CT)检测下颌下涎石的性能。

方法

纳入13例疑似下颌下涎石且接受了超声检查及CT或MRI检查的患者。涎石通过CT(11例)或MRI(2例)诊断。根据下颌舌骨肌周围的点将下颌下导管分为远段和近段导管。位于近段导管的涎石难以与位于下颌下腺(SMG)内的涎石区分。因此,涎石的位置分类如下:在SMG/近段导管内和在远段导管内。将超声检查结果与CT/MRI结果进行比较。

结果

在纳入的13例患者中,2例在SMG/近段导管和远段导管均有涎石,3例在SMG/近段导管有涎石,5例在CT或MRI上显示远段导管有涎石。在这个小队列中,超声检查检测出了所有位于SMG/近段导管的5颗涎石;然而,在7例位于远段导管的涎石病例中,超声检查仅能检测出3例。

结论

远段导管涎石的发生率高于SMG/近段导管。与CT/MRI相比,超声检查在SMG/近段导管表现良好,但在远段导管则不然。
