ABSTRACT
A total of 87 patients with primary Sjögren′s syndrome (pSS) admitted in Jiangyin Hospital affiliated to South-East University Medical College from August 2014 to September 2018 were enrolled. According to severity, the ultrasonographic images of salivary glands were analyzed and graded to 0-4 scores, it is defined as positive if the scores ≥ 2. The ultrasonographic positive rate of submandibular glands and parotid glands were 94.3% (164/174) and 71.3% (124/174), respectively (χ2=32.22, P<0.05). The median scores of submandibular glands and parotid glands were 3 and 2 (Z=9.70, P<0.05). No significant difference was found in the ultrasonographic scores between the right and left glands of the same salivary glands (P>0.05). The result indicates that the damage of submandibular glands is more severe than that of parotid glands in patients with pSS.
