The auriculotemporal syndrome, also known as gustatory sweating or Frey’s syndrome, is a condition characterized by sweating and flushing of the cutaneous territory innervated by the auriculotemporal nerve while eating. Frey’s syndrome is probably an inevitable sequela of parotid gland surgery. Once it appears, it persists for the rest of the patient’s life if not treated. It has been reported that performance on the Minor test after parotid gland surgery is 100% positive and 50% of patients are symptomatic, experiencing sweating during meals. About 15% consider their symptoms serious. In this article we present the results of our study of the treatment of Frey’s syndrome by intradermal injection of botulinum toxin A and the follow-up of the patients. The patients’ symptoms disappeared during a mean period of 16 months with some individual variability. These results suggest that injection of botulinum toxin A could be a technique of choice for established Frey’s syndrome.
