摘　　要：目的:探讨腮腺造影后锥形束CT(CBCT)在慢性腮腺炎诊断中的应用。方法:对20例可疑慢性腮腺炎症的患者行腮腺造影术后进行CBCT检查,对多平面重建(MPR)横断面、冠状面、矢状面及三维重建图像进行分析。结果:MPR横断面、冠状面、矢状面和三维重建图像均可以从任意方向显示腺体和导管,6例慢性复发性腮腺炎腮腺造影CBCT表现为腺体实质内末梢导管呈现大量点球状扩张为特征,其中4例主导管系统未见异常,2例呈现管炎表现;14例慢性阻塞性腮腺炎腮腺造影CBCT表现为主导管不规则扩张及狭窄,3例出现腺体内"点扩",2例查及阴性涎石。结论:腮腺造影CBCT检查能清晰立体地显示腮腺导管系统和腺体影像,可以作为临床检查慢性腮腺炎的有效方法,对指导临床治疗有重要意义。Objective： To explore the value of cone beam CT（CBCT） scanning following parotid sialography in the diagnosis of chronic parotitis. Methods： 20 cases of suspected chronic parotitis patients underwent parotid gland sialography followed by CBCT scanning. The images were observed by transverse plane, coronal plane, sagittal plane of multiplanar reconstruction（MPR） and 3D reconstruction. Results： The acinus and ducts system of parotid were clearly displayed from any orientation by MPR and 3D-reconstructed images. The images of 6 cases of chronic recurrent parotitis in CBCT sialography were charactered by punctiform dilatation in whole parotid gland, 4 of them showed a normal ductal system, while 2 exhibited expression of ductal inflammation. The images of 14 cases of chronic obstructive parotitis showed irregular duetal dilatations and stenosis. Punctiform dilatations were found in 2 cases, and small filling defects（ negative salivary calculi） in 3 cases. Conclusion： CBCT sialography is an effective clinical examination for the diagnosis and treatment chronic parotitis.
