Early results using a porcine dermal collagen implant as an interpositional barrier to prevent recurrent Freyʹs syndrome

Freyʹs syndrome is a common complication of salivary gland surgery. Although it is usually preventable by raising the skin flap in the superficial musculoaponeurotic system layer, the treatment of the established condition often requires further surgery. There are many surgical options to treat this condition. The method described in this paper avoids the morbidity of a second operative site by using a biocompatible interpositional layer to prevent the sweat glands of the skin being inappropriately cross-innervated. The follow-up period on both patients was 12 months. This factor needs to be taken into account despite the early improvement observed.
