How can Frey's syndrome be prevented or treated following parotid surgery?

BACKGROUND After parotid surgery, traumatized auriculotemporal, postganglionic, parasympathetic nerve fibers reinnervate the sweat glands and subcutaneous vessels resulting in gustatory sweating and facial flushing. Because Frey’s syndrome (FS) does not spontaneously resolve, multiple prevention and treatment strategies have been proposed. The literature supports evidencebased best practices for procedures in selected patients directed at the prevention and treatment of FS who are likely to have improved long-term quality of life after parotidectomy.
