Salivary gland stones are calcium residues and other minerals. They can occur in all types of salivary gland ducts. Most stones affect the submandibular glands located at the floor of the mouth. Some stones can also affect the parotid glands located in front of the ear or the sublingual glands under the tongue. One or more stones may be seen in the affected salivary gland.⠀ ⠀ Symptoms:⠀ Salivary gland stones usually do not cause symptoms while they form, and they can sometimes disappear on their own. Stones may vary in size. Large stones can block the flow of saliva in the gland. This blockage can cause saliva to accumulate behind the stone, causing pain and swelling. In case of sudden painful swelling while eating, stones should definitely come to mind.⠀ ⠀ Diagnosis:⠀ After the physical examination, ultrasound, direct radiographs or CT may be requested to determine the number of stones and their exact location. Salivary gland stones can usually be easily seen on radiographs due to their calcium content.⠀ ⠀ Treatment:⠀ Sialendoscopy can be performed for stones in the salivary gland duct close to the mouth. However, surgery is recommended for stones that are very large or very difficult to remove. In some cases, the affected salivary gland may also need to be removed.
