Quick Reference

[L. Frey (1889–1942), Polish neurologist] A rare neurological condition characterized by warmth, redness, and gustatory sweating (sweating in the anticipation of eating) of the area of the cheek adjacent to the ear. It follows trauma to the overlying skin or as a side-effect of parotid gland surgery. It is thought to be caused by post-traumatic crossover of sympathetic and parasympathetic innervation to the gland and skin, respectively.
