Methods
From the electronic patient files, we extracted following variables: gender, age at first intervention, location of the symptomatic salivary gland, indication for sialendoscopy, findings at sialendoscopy, complications and outcome as assessed during follow-up consultations in our department. Peroperatively, we used the LSD classification14 (Table 1) to prospectively classify the different salivary gland pathologies that were encountered. To assess symptom control and gland-related quality of life at long-term follow-up, we used the questionnaire designed by Gillespie et al10.
