[Evaluation of parotid sialography and labial salivary gland biopsy to the diagnosis of Sjögren syndrome].

OBJECTIVE: To investigate the relationship between the change of parotid sialograms and the results of labial gland biopsies in the patients with Sjögren syndrome (SS). METHODS: Parotid sialography and labial salivary gland biopsy were performed on 100 patients with Sjögren syndrome. RESULTS: The sialectasis of parotid terminal ducts was found in 87 patients, the widening only of main ducts was found in 8 patients, and 5 cases showed normal sialograms. The results of labial salivary gland biopsies showed, that 90 cases had focal lymphocytic sialadenitis (Zhen Linfan's grade score of 2), 59 cases had a score of 4 accoding to Chisholm's grading score; moderate scattered lymphocitic infiltration was shown in 10 patients. CONCLUSION: Our results suggested that the lesions of parotid gland and labial salivary gland in SS were concerted closely. Therefore a new way of combining the changes of parotid gland and labial salivary gland for the diagnose of SS was proposed.
