Frey’s syndrome arises as a complication of parotid surgery usually manifesting several months after operation.
It is characterised by sweating and flushing of the preauricular skin during mastication causing nuisance to the person or social embarrassment.It is the result of aberrant innervation of sweat glands by parasympathetic secretomotor fibers which are destined for the parotid.Now instead of causing secretion from parotid,they cause secretion from the sweat glands.
Treatment:
The condition can be treated by ;
- Tympanic neurectomy which intercept these parasympathetic fibers at the level of middle ear.
- Place a sheet of fascia lata between the skin and underlying fat
- Subcutaneous infiltration of botulinum toxin
