Sialendoscopic removal of fish bone-induced sialoliths in the duct of the submandibular gland

Obstructive sialadenitis of the submandibular gland is commonly caused by sialoliths, but more rarely by foreign body-induced sialoliths. Here, we report minimally invasive sialendoscopic removal of fish bone-induced sialoliths in the duct of the submandibular gland. A 43-year-old woman presented with recurrent swelling of the right submandibular gland at other hospital. Computed tomography (CT) showed an 8-mm linear calcification in the posterior part of Wharton's duct. The lesion was deemed difficult to remove and she was followed up.
