Frey syndrome
Pronunciation: FRY sin-drohm
Post-surgical complication following parotidectomy characterized by gustatory sweating over the affected cheek area.
Full Definition
A well-recognized complication of parotid gland surgery resulting from aberrant regeneration of parasympathetic nerve fibers. Also known as gustatory sweating or auriculotemporal syndrome, it occurs when severed parasympathetic fibers intended for salivary gland innervation instead connect to sweat glands in the overlying skin. Patients experience sweating and flushing of the cheek when eating, particularly with sour or spicy foods. Treatment options include topical antiperspirants, botulinum toxin injections, or surgical interposition of fascial barriers.
Usage
