<prompt> Freys syndrome is caused by:Aberrant reinnervation of parasympathetic fibres of auriculotemporal nerve with sympathetic sweat glandsAberrant reinnervation of parasympathetic fibres of auriculotemporal nerve with Greater superficial petrosal nerveAbnormal cross innervation of Facial nerve with greater auricular nerveAbnormal cross innervation of Facial nerve with auriculotemporal nerve  <response>: Freys syndrome is gustatory sweating i.e. when the patient eats, he has sweating over the cheek skin over the parotid. In section of auriculotemporal nerve during parotid surgery, the nerve aberrantly reconnects with the sympathetic sweat glands of the skin overlying the parotid.
