Congenital Frey's syndrome associated with nontraumatic bilateral trifid mandibular condyle.

Congenital Frey's syndrome and bilateral trifid mandibular condyle are two different entities. The occurrence of both together is rare and has not been reported in the literature. This article describes the case of a 17-year-old male patient who complained of bilateral warmness, flushing and sweating in the preauricular area after eating spicy and sour foods since childhood. He had no complaint related to the functions of the temporomandibular joint and had no history of facial trauma. The patient was treated with injections of botulinum toxin A and the signs and symptoms of Frey's syndrome improved significantly.
