Ranula is a mucocele under the tongue. Ranulas may be larger than mucoceles at other sites; they are usually associated with the sublingual gland, and less often they arise from the submandibular gland or a minor salivary gland. [11] Rarely, a ranula may descend into the neck rather than the mouth (plunging ranula).
Sialolithiasis (also termed salivary calculi, [1] or salivary stones) [1] is a crystallopathy where a calcified mass or sialolith forms within a salivary gland, usually in the duct of the submandibular gland (also termed "Wharton's duct"). Less commonly the parotid gland or rarely the sublingual gland or a minor salivary gland may develop ...
Saliva stagnates and forms a mucus plug behind the stricture during sleep when the salivary output of the parotid is reduced. Then, when salivary secretion is stimulated, the mucus plug becomes stuck in the stricture. [1] The backlog of saliva behind the blockage causes the swelling, and the increased pressure inside the gland causes the pain.
Salivary gland dysfunction is either a reduced (hyposalivation), or an increased (hypersalivation) production of saliva. Xerostomia, the symptom of dry mouth is often caused by hyposalivation and is associated with significant impairment of quality of life. [34] Following radiotherapy of the head and neck region, salivary gland dysfunction is a ...
The most usual source of the mucin spillage is the sublingual salivary gland, but ranulae may also arise from the submandibular duct or the minor salivary glands in the floor of the mouth. A cervical ranula occurs when the spilled mucin dissects its way through the mylohyoid muscle , [ 1 ] which separates the sublingual space from the ...
This occurs because of a ruptured salivary gland duct usually caused by local trauma (damage) in the case of mucous extravasation phenomenon and an obstructed or ruptured salivary duct in the case of a mucus retention cyst. The mucocele has a bluish, translucent color, and is more commonly found in children and young adults.
Salivary stones (sialolith) may be evident with cystic dilation of the salivary ducts and periductal fibrosis. Mucus extravasation may also be observed. Common observations of chronic sialadenitis include chronic inflammatory infiltrate (lymphocytes, plasma cells and macrophages), fibrosis, acinar atrophy, and mucous cell metaplasia of the ...
Sialodochitis (also termed ductal sialadenitis), [1] is inflammation of the duct system of a salivary gland. [2] This is compared to sialadenitis, which is inflammation of the gland parenchyma. [3] Sialodochitis may be associated with salivary duct strictures and salivary stones. [4] It is common in both the parotid glands and submandibular ...
