Auriculotemporal syndrome

Auriculotemporal syndrome (synonym: the syndrome USNO-temporal nerve syndrome Frey, parotid-temporal hyperhidrosis) is a syndrome characterized by erythema, increased sweating, and in some cases decrease skin sensitivity in the parotid-temporal region. Areas of congestion and excessive sweating fully with the zones sensitivity disorders are not the same. Redness and increased sweating occur only when eating, causing increased salivation (some patients need only think about it). Chewing movements themselves as fresh liquid food, salivary flow or no cause, or it is insignificant. Described violations are observed in the area of innervation not only USNO-temporal, but also a great ear and small occipital nerve. Auriculotemporal syndrome is usually seen in people with the disease salivary gland has led to cicatricial its changes.
The mechanism of the syndrome has not been studied. At its core, it seems, increased reflex reaction. In healthy people often receive a tasty and abundant meal accompanied by a reflex emerging redness and increased sweating face. Nerve trunks (and including vegetative fiber), Innervate the blood vessels and sweat glands of the skin of the parotid region, may be subject to compression of the scars and therefore permanent irritation. Under such conditions, any irritation taste receptors causes increased reflex in the form of congestion and increased sweating.
Treatment aimed at resorption of scars in the parotid gland (mud and paraffin therapy, electrophoresis with potassium iodide), often has a positive effect. In some cases the success brought transection of USNO-temporal and large ear nerves.
