Sialolithiasis refers to the presence of calcified structures within the ducts of salivary glands and is the most common disorder affecting these glands. Approximately 80-95% of sialoliths occur in the submandibular salivary gland. The occurrence rate of sialoliths is about 12 per 1000 individuals, with men being affected approximately twice as often as women. Sialoliths can be diagnosed through clinical examination, conventional radiography, computed tomography, and ultrasonography. Typical clinical indicators of sialoliths include painless swelling, sometimes extensive, often accompanied by difficulty opening the mouth (trismus) during eating, and symptoms that vary from mild discomfort to severe pain. This case report illustrates the clinical, radiological signs, and surgical treatment of a salivary stone in the submandibular gland.
