Unusual Clinical Scenarios to Consider in Patient Management Frey syndrome is a masquerader of food allergy, especially in children.

The overarching theme for the surgical prevention of Frey syndrome has been the incorporation and maintenance of a barrier between the underlying postganglionic parasympathetic nerve endings within the transected parotid and the overlying cutaneous tissue.

In contrast to food allergy, Frey syndrome is usually unilateral, with auriculootemporal segmental distribution in the areas innervated by the auriculotemporal nerve.
