Comparison of ultrasonographic findings between parotid glands and submandibular glands in primary Sjögren′s syndrome

A total of 87 patients with primary Sjogren′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 result indicates that the damage of submandibular glands is more severe than that of parotid glands in patients with pSS. Key words: Sjogren′s syndrome, primary; Ultrasonography; Diagnosis
