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