Swelling of the submandibular gland as seen from the outside The stone seen in the submandibular duct on the person's right side. Signs and symptoms are variable and depend largely upon whether the obstruction of the duct is complete or partial, and how much resultant pressure is created within the gland. [1]
Formation of stones in glandular ducts can result in the development of obstructive sialadenitis. There may be a history of abrupt episodic swelling of the parotid or submandibular gland which is usually painful. These episodes typically occur around meal times, lasting 2–3 hours, and gradually subside.
Strictures are the second most common cause of chronic obstructive sialadenitis, after salivary stones. [1] In line with this, strictures may give rise to the "meal time syndrome", [1] where there is pain and swelling of the involved salivary gland upon salivary stimulation with the sight, smell and taste of food.
The submandibular gland is medial to the angle of the mandible, and it drains its mixture of serous and mucous saliva via the submandibular duct (Wharton duct) into the mouth, usually opening in a punctum in the floor of mouth. The sublingual gland is below the tongue, on the floor of the mouth; it drains its mostly mucous saliva into the mouth ...
The submandibular duct (also Wharton's duct or historically submaxillary duct) is one of the salivary excretory ducts. It is about 5 cm long, and its wall is much thinner than that of the parotid duct. It drains saliva from each bilateral submandibular gland and sublingual gland to the sublingual caruncle in the floor of the mouth.
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 ...
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 ...
Neoplasms, such as metastatic squamous cell carcinoma to the submandibular lymph nodes or a salivary gland tumour, could create a similar appearance but rarely have such well defined borders and can usually be palpated in the floor of the mouth or submandibular triangle of the neck as a hard mass. CT and clinical exam is typically sufficient to ...
