안면 둔상 후 발생한 Frey 증후군 1예

Frey’s syndrome is a syndrome of localized preauricular facial sweating during mastication associated with flushing and pain. It may be a sequela of parotid surgery or penetrating injuries to the parotid gland and has been reported as a result of traumatic forceps delivery, central nervous system diseases, cervical sympathectomies, radical neck dissections, and subcondylar fracture. A 21-year-old male patient came to our hospital because of diplopia for 13 days after right facial trauma. Right blowout fracture of the inferior orbital wall was observed from computed tomography. He suffered diplopia from all directions of gaze, and we carried out reduction of right blowout fracture with transorbital approach on 15 days after trauma. On 40 days after the operation, he sweated on the right side of forehead and auricle when he ate food, and Minor’s starch test showed a positive response. We followed up and observed the symptoms because they were not serious, and the patient’s subjective symptoms were disappeared after 3 months. We report a case of Frey’s syndrome after blunt facial trauma with a review of literature. (J Clinical Otolaryngol 2006;17:281-284)
