锥形束CT在颌下腺结石诊断中的应用

目的:探讨锥形束CT(CBCT)对颌下腺结石的临床诊断价值。方法:利用CBCT的影像诊断系统对9例颌下腺肿大患者的下颌下区进行轴面、冠状面、矢状面及三维重建影像检查,同时进行测量分析。结果:8例患者经手术治疗后确定的结石大小、位置,与CBCT检查结果一致,1例术前自行排石。结论:CBCT对颌下腺结石有较高的诊断价值,能确定结石的数目、大小并定位,准确性高,为临床手术治疗提供直接依据。

CBCT on the Diagnosis of Sialolithiasis of Submandibular Gland

Objective： To discuss the clinical value of cone beam computed tomography （CBCT） in diagnosis of submandibular gland and Wharton＇s duct sialoliths. Methods： 9 patients who have had tumefaetion of submandibular gland were examined and analyzed by axial plane, coronal section, vertical plane and three-dimensional reconstruction imaging of CBCT. Results： 4 cases of salivary calculi located at Wharton＇s duct. 4 cases occurred in the junction of submandibular gland and duct. Only one salivary stone located in the submandibular gland proper. One sialolith discharged spontaneously before operation. The operation findings of 8 patients showed conformity with CBCT examination. Conclusion： CBCT can provide direct guidance for clinical treatment of submandibular gland and/or Wharton＇s duct salivary stones.
