<p>Sialoliths commonly occur in the submandibular grand, and parotid gland sialoliths are rare. We report the endoscopic removal of a parenchymal sialolith of the parotid gland. A 56-year-old man with right parotid swelling was referred to our department for endoscopic removal of a parenchymal sialolith of the parotid gland. Computed tomography showed that the parenchymal sialolith measured 3.6 × 2.5 × 1.7 mm. Diagnostic sialendoscopy was performed with the patient under local anesthesia, and the parenchymal sialolith was found in the endoscopic view. Therefore, the patient underwent endoscopic removal of the sialolith under general anesthesia as minimally invasive surgery. Complete removal was performed using a microbur and basket, and the postoperative course has been uneventful for 1 year 9 months.</p>
