Chemical Denervation in Gustatory Sweating

Content Contributor

Since Frey syndrome (gustatory sweating) includes aberrant reinnervation of superficial sweat glands with parasympathetic nerves of the parotid gland, selectively rendering these nerves inoperable will decrease the ill effects of this disorder. Botox is used to carry out this action by injecting specific amounts into the area surrounding the parotid gland in the cheek, or where the parotid gland used to be. The aberrant parasympathetic nerves that innervate the superficial sweat gland will therefore be unable to neurotrasmit, and the superficial sweat glands should no longer be stimulated by foods or flavors.
