超声在下颌下腺导管结石诊断治疗中的应用分析

目的研究下颌下腺导管结石的超声影像学特点。方法应用彩色多普勒超声对56例下颌下腺导管结石患者进行检查，得到下颌下腺导管和结石及异物声像图，分析其特点，经手术或内镜取石治疗后行对比观察。结果经观察56例均见结石，下颌下腺主导管结石32例；下颌下腺-腺管交界处结石15例；下颌下腺腺体内结石9例。其中导管扩张51例，不扩张5例，提示手术与超声诊断基本相符。结论超声可以较直观地显示下颌下腺导管结石的大小和结石在导管中的位置，为临床诊断及治疗提供了较可靠的依据。

Application analysis of ultrasonic in diagnosising and treating submandibular duct calculi

Objective To investigate the characteristics of submandibular duct calculi in ultrasonic tomography, and provide reliable diagnosis methods for diagnosing submandibular duct calculi and foreign body in clinical. Methods Using color doppler ultrasound to inspect 56 patients with submandibular duct calculi. The features of ultrasonogram of submandibular duct calculi and foreign body were analysied. To compare ultrasonogram after treatment by operation or endoscopic to take calculi. Results 56 cases all were with calculi. 32 cases with submandibular duct master duct calculi, 15 cases with submandibular duct-crypt juncture calculi, 9 cases with calculi in submandibular duct gland. 51 cases with duct dilatation while 5 cases with duct not dilatation. The results shown that the diagnosis are basically same between operation and ultrasonic. Conclusion Ultrasonic can visualy display the size and position of submandibular duct calculi, and provide reliable basis for clinical diagnosis.
