Sialolith commonly occurs unilaterally in the submandibular gland of adults, while submandibular gland stones occur rarely in children. Here we report a case of bilateral submandibular gland stones in a child.
A 7-year-old boy had swelling of the left submandibular gland. The patient was referred to our department for endoscopic removal to avoid submandibular gland removal after bilateral hilar stones of the submandibular gland had been diagnosed in another hospital. Because the left stone, 1.7×1.7×1.1mm in size, was located at the orifice of the papilla at the first visit, the stone was removed under local anesthesia. But, the right stone, 3.0×1.6×1.5mm in size, was located at the hilar, and the patient was followed up. Eight months after the initial visit, the patient had swelling of the right submandibular gland. Because the right stone was located at the orifice of the papilla, the right stone was removed under local anesthesia. There was no recurrence after the removal of submandibular gland stones.
