The parotid glands are the largest salivary auriculogemporal in the body located just below the ears on either side of the face. Previous studies have demonstrated that patients undergoing BTA injection demonstrate improvement in symptoms of gustatory sweating and flushing.

Individuals are then given an oral stimulus usually a highly acidic food such as a lemon wedge.

Auriculotemporal Syndrome (Frey Syndrome)

Frey syndrome results from synkinetic autonomic reinnervation by transected postganglionic parasympathetic nerve fiber within the parotid gland to the overlying sweat glands of the skin. Therefore, the parasympathetic nerves that normally tell the parotid glands to produce saliva in response to tasting food now respond by instructing the sweat glands to produce sweat and the blood vessels to widen dilate. Powered By Decision Support in Medicine.

C Postganglionic parasympathetic nerve fibers innervating the cutaneous sweat gland that results in gustatory sweating. It was first described as a composite flap for ear reconstruction in by Fox and Edgerton 12 and was later adapted to a fascia flap.

J Am Med Assoc. Superficial musculoaponeurotic system flap Another technique, focused on creating a physical barrier between the underlying regenerating auriculotemporal nerve fibers and the overlying dermis, is a superficial musculoaponeurotic system SMAS flap. Our website uses cookies to enhance your experience. Diagnosis of Frey syndrome is based on clinical history, but confirmatory testing can be done with a Minor starch-iodine test. Within the facial skin, the sweat glands are positioned at the same level or slightly deeper than the base of the hair follicles.

The response may last for a period of 6 months and the treatment can be repeated. Retrieved from ” https: This may occur consistently with every solid food feeding. Br J Oral Maxillofac Surg.

Repeated botulinum toxin type A injections to treat patients with Frey syndrome. Based on this, it has been presumed that increasing the thickness of the elevated skin flap, to keep the sweat glands from being exposed, affords protection from the aberrant parasympathetic nerve regeneration that results in Frey syndrome.

Normally, damaged nerve fiber s eventually heal themselves regenerate.
