He had been diagnosed as sialorrhea and submandibular gland hyperfunction by stomatologist, then had unilateral submandibular gland resection 13 years ago, but the symptom relief was not satisfactory. After that, he had been treated with glycopyrrolate for less than a year, which was withdrawn because of the short duration of symptomatic control after each tablet take-in and intolerable side effects. With the wish to receive a new treatment with long term effectiveness, low re-operation risk and normal preserved saliva secretion function, the patient was subject to MWA for the right submandibular gland. After systematic clinical evaluation, US-guided percutaneous MWA was successfully performed with an uneventful post-operative course. The volume of the right submandibular gland and ablated area were measured precisely by an ablation planning software system with automatic volume measurement function based on three-dimensional reconstruction of the pre-operative and post-operative enhanced magnetic resonance imaging (MRI) raw data. Finally, the ablated volume was calculated as 62.2% of the whole right submandibular gland. The patient was discharged 1 day after the operation, with symptoms relieved significantly, the mean value of whole saliva flow rate (SFR) decreased from 11\u200aml to 7.5\u200aml per 15 minutes. During the follow up by phone three months after operation, the patient reported that the treatment effect was satisfactory, whereas the SFR value became stable as 7\u200aml per 15 minutes, drooling frequency and drooling severity (DFDS) score decreased from 6 to 5, drooling impact scale (DIS) score decreased from 43 to 26. US-guided percutaneous MWA of submandibular gland seems to be an alternative, minimal invasive, and effective treatment for refractory sialorrhea. We described a patient with refractory sialorrhea treated successfully with ultrasound (US) guided percutaneous microwave ablation (MWA).<\/jats:p>","DOI":"10.3233\/ch-211115","type":"journal-article","created":{"date-parts":[[2021,3,2]],"date-time":"2021-03-02T13:02:58Z","timestamp":1614690178000},"page":"215-226","source":"Crossref","is-referenced-by-count":2,"title":["US-guided
