The diagnostic value of cone-beam CT sialography for non-neoplastic diseases of the parotid gland

Abstract

Abstract: PURPOSE: The aim of this study was to assess cone-beam CT (CBCT) sialography in the radiodiagnosis of non-neoplastic diseases of the parotid gland. METHODS: For patients with recurrent swelling of the parotid gland, CBCT and three-dimensional reconstruction of the parotid duct were performed after routine examination. RESULTS: Of 50 patients, 30 were diagnosed as chronic obstructive parotitis, 12 were diagnosed as chronic recurrent parotitis and 8 were diagnosed as Sj?觟gren's syndrome. In these patients, CBCT sialography could clearly show the length, width, and filling defect of the parotid gland. For patients with chronic recurrent parotitis and Sj?觟gren's syndrome, CBCT sialography can display the tertiary to quaternary branches of the parotid gland clearly. CONCLUSIONS: CBCT sialography can be used in the diagnosis of non-neoplastic diseases of the parotid gland, and CBCT sialography can provide multidimensional images of the lesion of the gland and duct.
