Palpable hard lump, if the stone is located near the end of the duct. [1] [3] If the stone is near the submandibular duct orifice, the lump may be felt under the tongue. Lack of saliva coming from the duct (total obstruction). [3] Erythema (redness) of the floor of the mouth (infection). [3] Pus discharging from the duct (infection). [3]
A sialolithiasis (a salivary calculus or stone) may cause blockage of the ducts, most commonly the submandibular ducts, causing pain and swelling of the gland. [ 33 ] Salivary gland dysfunction refers to either xerostomia (the symptom of dry mouth) or salivary gland hypofunction (reduced production of saliva); it is associated with significant ...
When the diameter of the stone is 5mm or less, it can be removed purely by an endoscopic technique, particularly when the stone is located above the muscles that comprise the floor of the mouth. The four common techniques used to remove the salivary gland stones are: The grasping technique; Using a small wire basket retrieval system
A calculus (pl.: calculi), often called a stone, is a concretion of material, usually mineral salts, that forms in an organ or duct of the body. Formation of calculi is known as lithiasis (/ ˌ l ɪ ˈ θ aɪ ə s ɪ s /). Stones can cause a number of medical conditions.
The third pair are the sublingual glands located underneath the tongue and their secretion is mainly mucous with a small percentage of saliva. Within the oral mucosa, and also on the tongue, palates, and floor of the mouth, are the minor salivary glands; their secretions are mainly mucous and they are innervated by the facial nerve . [12]
Stones may be removed by manipulation in the doctor's office, or, in the worst cases, by surgery. Lithotripsy, also known as "shock wave" treatment, is best known for its use breaking up kidney stones. Lithotripsy can now be used on salivary stones as well. Ultrasound waves break up the stones, and the fragments flush out of the salivary duct. [7]
Sialography (also termed radiosialography) is the radiographic examination of the salivary glands. It usually involves the injection of a small amount of contrast medium into the salivary duct of a single gland, followed by routine X-ray projections. [1] The resulting image is called a sialogram.
In summary, salivary glands are classified as heterocrine glands because they have a dual role in both exocrine and endocrine functions. They primarily secrete saliva into the oral cavity for digestion, but they can also release specific hormones into the bloodstream with broader physiological effects.
