The symptoms of Frey's syndrome are redness and sweating on the cheek area adjacent to the ear (see focal hyperhidrosis). They can appear when the affected person eats, sees, dreams, thinks about, or talks about certain kinds of food which produce strong salivation. [3] Observing sweating in the region after eating a lemon wedge may be diagnostic.
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.
Cosmetic deformity is relatively minor, although symptoms may recur in up to 11-13%, of these not all require further treatment. The occurrence of recurrent symptoms is lower (4%) for subtotal parotidectomy. The choice of the surgical procedure is determined by the extent of the disease and the patient’s preference.
The International Association for the Study of Pain defines burning mouth syndrome as "a distinctive nosological entity characterized by unremitting oral burning or similar pain in the absence of detectable mucosal changes" [1] and "burning pain in the tongue or other oral mucous membranes", [8] and the International Headache Society defines it ...
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.
Pneumoparotitis (also termed pneumosialadenitis [1] wind parotitis, [1] surgical mumps, [2] or anaesthesia mumps), [2] is a rare cause of parotid gland swelling which occurs when air is forced through the parotid (Stensen) duct resulting in inflation of the duct.
Angina bullosa haemorrhagica is a condition of the mucous membranes characterized by the sudden appearance of one or more blood blisters within the oral cavity. [1]: 808 The lesions, which may be caused by mild trauma to the mouth tissues such as hot foods, typically rupture quickly and heal without scarring or further discomfort. [2]
Odynophagia is pain when swallowing. [1] [2] The pain may be felt in the mouth or throat and can occur with or without difficulty swallowing. [3] The pain may be described as an ache, burning sensation, or occasionally a stabbing pain that radiates to the back. [4] Odynophagia often results in inadvertent weight loss.
