A case of bilateral (multiple) submandibular sialolithiasis

We recently experienced a rare case of bilateral (multiple) sialolithiasis of the submandibular gland. A 79-year-old female was referred to us for extraction of the first molar in the right mandible. While she had slight swelling in the right submandibular region, X-ray showed the presence of small calcific densities not only adjacent to the angle of the right mandible but also to that of the left. Purulent material was discharged from the right submandibular duct, but there were no symptoms in the left. Computed tomography revealed eight calculi: five calculi in the right submandibular gland, one in the right submandibular duct, and two in the left submandibular gland. After antibiotic therapy, all calculi and both of the submandibular glands were removed surgically. As of the present, the prognosis of the patient is good.
