title: Sialendoscopy-assisted treatment for chronic obstructive parotitis related to Sjogren syndrome.
abstract: OBJECTIVE
  Chronic obstructive parotitis related to Sjogren syndrome is not uncommon, but it is rarely reported in the literature. The aim of this study was to describe our experience in the treatment of chronic obstructive parotitis related to Sjogren syndrome.
  
  
  METHODS
  Seventeen cases of chronic obstructive parotitis related to Sjogren syndrome treated with sialendoscopy from June 2014 to June 2015 at the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medical University, were retrospectively reviewed. The cohort underwent ultrasonography, salivary gland scintigraphy, and sialography before sialendoscopy. All patients were asked to complete a visual analogue scale (VAS) evaluation before and 6 months after surgery. A paired t test was conducted, and P < .05 was considered statistically significant.
  
  
  RESULTS
  The 17 study patients (27 parotid glands) successfully underwent interventional sialendoscopy under local anesthesia. The mean preoperative VAS score was 6, and the mean VAS score 6 months after sialendoscopy was significantly lower at 4.5 (P < .05).
  
  
  CONCLUSIONS
  Interventional sialendoscopy plays a significant role in the treatment of chronic obstructive parotitis related to Sjogren syndrome.
