GIANT SIALOLITH IN SUBMANDIBULAR DUCT: CLINICAL CASE

Sialolithiasis is a pathology arising from the formation of mineralized material inside the salivary gland or duct, causing obstruction of the salivary flow. The submandibular gland is the most affected, followed by the parotid gland. Clinically presenting pain and edema. Radiography (occlusal), sialography, and computed tomography help the diagnosis. The objective of this study is to report the case of a patient, 46 years old, with a volumetric increase in the region of the right submandibular duct, covered by hyperemic mucosa, with a hard and painful consistency with purulent exudate exit by the sublingual caruncle. In the occlusal radiography revealed a radiopaque image of cylindrical shape compatible with submandibular duct path, with diagnostic hypothesis of sialolithiasis. An incision was made on the submandibular duct, followed by removal of the 3 x 1 cm sialolith. The patient progressed with improvement. Giant sialoliths are rare, so this case contributes as knowledge for conducting new cases.
