Frey syndrome occurs following surgeries around the parotid. A 61-year-old woman post superficial parotidectomy pre-sented after 2 years with symptoms of gustatory sweating. Minor test was positive (9cm(2) area). Topical antihyperhydrotics and stellate ganglion blocks provided no benefit. Botulinum toxin was administered intracutaneously. Symptoms resolved with in 48 hours. Minor test was negative at 10 month follow up. Most of the surgical and medical techniques described to treat Frey syndrome have high failure rate with short term relief. Botulinum toxin injection is minimally invasive and produces a long lasting effect.
