Sialadenitis (sialoadenitis) is inflammation of salivary glands, usually the major ones, the most common being the parotid gland, followed by submandibular and sublingual glands. [1] It should not be confused with sialadenosis (sialosis) which is a non-inflammatory enlargement of the major salivary glands.
The inflammatory lesions in Küttner's tumor may occur on one side (unilateral) or both sides (bilateral), predominantly involving the submandibular gland, [3] but is also known to occur in other major and minor salivary glands, [4] including the parotid gland. [5] [6] Overall, salivary gland tumors are relatively rare, with approximately 2.5 ...
The two parotid glands are major salivary glands wrapped around the mandibular ramus in humans. [6] These are largest of the salivary glands, secreting saliva to facilitate mastication and swallowing, and amylase to begin the digestion of starches. [7] It is the serous type of gland which secretes alpha-amylase (also known as ptyalin). [8]
Sialadenitis is inflammation of the salivary glands, which may cause acinar atrophy and create an appearance known as "pruning of the tree" on a sialogram, where there are less branches visible from the duct system. A space occupying lesion that occurs within or adjacent to a salivary gland can displace the normal anatomy of the gland.
Salivary gland dysfunction affects the flow, amount, or quality of saliva produced. A reduced salivation is termed hyposalivation.Hyposalivation often results in a dry mouth condition called xerostomia, and this can cause tooth decay due to the loss of the protective properties of saliva.
Mucoepidermoid carcinoma is a common malignant tumour of the salivary glands and has a low incidence of 4–13%. [13] Adenoid cystic carcinoma is also a common malignant salivary gland lesion and has an incidence of 4–8%. This carcinoma tends to invade nerves and can re-occur post-treatment.
Picture of the mouth showing the sublingual caruncle and related anatomical structures The submandibular duct arises from deep part of submandibular gland , a salivary gland . It begins by numerous branches from the superficial surface of the gland, and runs forward between the mylohyoid , hyoglossus , and genioglossus muscles .
Sialolithiasis refers to the formation of calculi within a salivary gland. If a calculus forms in the duct that drains the saliva from a salivary gland into the mouth, then saliva will be trapped in the gland. This may cause painful swelling and inflammation of the gland. Inflammation of a salivary gland is termed sialadenitis. Inflammation ...
