In most cases, both diagnostic and interventional sialendoscopy are well tolerated under local anaesthesia (LA) or under local anaesthesia with sedation (LAS), with reasonably low patient-reported discomfort. Sialendoscopy can be considered a patient-friendly and relatively painless, gland-preserving, minimally invasive procedure suitable for day surgery.


To investigate patient experience and compliance in sialendoscopy under LA/LAS.


This prospective study was conducted at an academic tertiary-care university hospital. During a period of 22 months, 89 patients between ages 16-81 years underwent diagnostic or interventional sialendoscopy under LA (20%) or LAS (80%). After the operation the patients filled in a questionnaire formulated by the authors concerning their procedure-related experiences. Patients' demographic data, ASA status score, pre- and intra-operative blood pressure and heart rate measurements, affected gland, operation time, intervention type, as well as pre-, peri-, and postoperative medication were gathered later from the medical records.


The level of discomfort and pain experienced during the operation was assessed as 'mild' or 'none' by 85% and 89% of the patients, respectively. The level of pain experienced after the operation was 'major' in 4% of patients and 'mild' or 'none' in the majority (87%) of patients. The patients' estimations showed no significant difference between the diagnostic and interventional procedures, although it seems that patients who underwent stone removal by transoral incision experienced the operation as a bit more uncomfortable and painful than other patients. Afterwards 97% of patients stated that they would agree to a new LA/LAS sialendoscopy in the future if needed.
