Results: Frey syndrome (SF) is a disease characterized by gustatory perspiration and facial erythema throughout chewing. It results from a sequel in the parotidectomy or lesion of the parotid glands. Studies report that SF is based on the theory of erroneous recovery between the parasympathetic and sympathetic systems, pointing out as solutions therapeutic or surgical procedures. Although the majority of patients with SF have moderate symptoms, the apparent incidence of this syndrome after parotidectomy should be discussed with the patient before surgery in the parotid region. Conclusion: Finally, the importance of knowledge of SF is emphasized for an accurate diagnosis and a correct treatment.
