Management of Frey syndrome using botulinum neurotoxin: a case report.
Frey syndrome is manifested clinically by hemifacial flushing and sweating after a gustatory stimulus. Frey syndrome is usually secondary to traumatic injury in the parotid region and is thought to be the result of misdirected re-sprouting of damaged autonomic nerve fibres. In this case report, we highlight the clinical and psychosocial aspects of Frey syndrome from a patient"s perspective, outline the pathophysiology of the condition and current management strategies, and describe the use of botulinum neurotoxin in the treatment of Frey syndrome.
