title: Patient-perceived benefit of sialendoscopy as measured by the Glasgow Benefit Inventory.
abstract: OBJECTIVE
  Evaluate the patient-perceived effect of sialendoscopy on patients with obstructive symptoms from the salivary glands.
  
  
  METHODS
  Retrospectively identified cohort used for a prospective study of all consecutive patients at the Department of Otorhinolaryngology at Vejle Hospital, Vejle, Denmark, March 2009 to December 2013.
  
  
  METHODS
  By chart review we recorded the patient's age, gender, date of the sialendoscopy, type of gland, sialolithiasis, successful extraction of sialolithiasis, stenosis of salivary ducts, dilation, type of saliva, and surgeon. The follow-up was done by applying the Glasgow Benefit Inventory questionnaire by letter and telephone.
  
  
  RESULTS
  There were 130 sialendoscopies performed on 116 patients. Of these, 24 patients were excluded due to subsequent surgery. Thus, 92 patients were eligible, of whom 80 responded, giving an 87% response rate. The Glasgow Benefit Inventory score had a predicted overall mean of 13.4 (95% confidence interval: 9.9 to 17.2). Significant positive outcomes by multiple regression were the presence of stones (P = 0.015) and examination of the parotid gland (P = 0.041).
  
  
  CONCLUSIONS
  Overall, there is a significant patient-perceived benefit from sialendoscopy, which is comparable to the benefit from tonsillectomy. The benefit is significantly higher if stones are found than not and for examination of the parotid gland as compared to the submandibular gland.
