We report a case of chronic obstructive sialadenitis (COS) successfully treated using a microburr® with parotid sialendoscopy. A 48-year-old woman was referred to our hospital with a history of multiple episodes of swelling and pain in her right parotid region for 5 years. Computed tomography revealed no pathologic findings. For diagnosis and treatment, we performed sialendoscopy of the parotid gland with the patient under general anesthesia and found a severe stricture in the region of the buccinator muscle and mucus plug formation. We diagnosed COS of the right parotid gland and dilated the stricture using a sialoballoon. However, the stricture recurred 1 month later; therefore, we performed sialendoscopy again and used a microburr® to dilate the stricture. After the operation, a stent was placed in Stensen’s duct for 6 weeks. However, the same symptoms recurred after removing it. Currently, the stent is in Stensen’s duct. There has been no evidence of recurrence after 1 year. Our patient’s course provides two important suggestions. First, a microburr® is useful for treating COS; second, a stent has to remain in the duct for a long time to prevent stricture recurrence.
