Gustatory sweating in a free flap

A case of Freyʹs syndrome arising in a free radial forearm flap used to reconstruct a defect in the parotid region is reported. To our knowledge, Freyʹs syndrome, although common following parotidectomy, has not been reported in a free flap. It is possible that parasympathetic secretomotor fibres gained access to the fasciocutaneous flap via the cutaneous nerve stumps in its edge, resulting in gustatory sweating.
