The Auriculotemporal Syndrome. a Clinical and Pharmacologic Study.

The auriculotemporal syndrome which develops after injury to the parotid gland, consists of flushing and profuse sweating, upon eating, over the cutaneous distribution of the auriculotemporal nerve on the injured side. Although there have been few cases reported since the original description by Frey (1) in 1923, the syndrome is not rare, having been noted repeatedly, for-example, in clinics observing patients after operation on a parotid gland (2, 3). The syndrome is of interest to the physiologist because it affords an opportunity to study the consequences of denervation of cholinergic end organs. It is our purpose to present three instances of this syndrome with some observations relating to its mechanism.
