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 ...
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 impairment of quality of life. [34] Following radiotherapy of the head and neck region, salivary gland dysfunction is a predictable side-effect. [34]
The most common location to find a mucocele is the inner surface of the lower lip. It can also be found on the inner side of the cheek (known as the buccal mucosa), on the anterior ventral tongue, and the floor of the mouth. When found on the floor of the mouth, the mucocele is referred to as a ranula. They are rarely found on the upper lip.
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.
A ranula is a type of mucocele, and therefore could be classified as a disorder of the salivary glands. Usually a ranula is confined to the floor of the mouth (termed a "simple ranula"). [6] An unusual variant is the cervical ranula (also called a plunging or diving ranula), where the swelling is in the neck rather than the floor of the mouth. [1]
Blockage, whether caused by salivary duct stones or external compression, may cause pain and swelling of the parotid gland . Koplik's spots which are pathognomonic of measles are found near the opening of the parotid duct. The parotid duct may be cannulated by inserting a tube through the internal orifice in the mouth. [2]
A minor salivary gland biopsy, usually taken from the lip, [26] may be carried out if there is a suspicion of organic disease of the salivary glands. [1] Blood tests and urinalysis may be involved to exclude a number of possible causes. [1] To investigate xerophthalmia, the Schirmer test of lacrimal flow may be indicated. [1]
Human Von Ebner's gland. Von Ebner's glands, also called Ebner's glands or gustatory glands, are exocrine glands found in the mouth. More specifically, they are serous salivary glands which reside adjacent to the moats surrounding the circumvallate and foliate papillae just anterior to the posterior third of the tongue in its submucosa, anterior to the terminal sulcus.
