Localized facial flushing in infancy. Auriculotemporal nerve (Frey) syndrome

Pediatric auriculotemporal nerve (Frey) syndrome

“…It is widely thought to be the result of aberrant cross-innervation of auriculotemporal nerve fibres following injury to this region. [1][2][3] Because both the parasympathetic and sympathetic nerve fibres use acetylcholine neurotransmitters, they can undergo cross regeneration such that impulses to the salivary gland paradoxically stimulate the sweat glands and subcutaneous vessels in the distribution of the au ri culotemporal nerve. [1][2][3] Pediatric auriculotemporal nerve syndrome can be characterized clinically as facial erythema and warmth; it is less commonly associated with the production of tears, as is seen in adults.…”

[1][2][3] Although long-term follow-up is not well documented in the literature, no proven treatments exist, and spontaneous remission or a dramatic reduction in symptoms has been reported to occur with growth. 1,3 For this reason, no specific therapy is recommended.…”
