Frey’s syndrome (auriculotemporal nerve syndrome), a rare yet well-documented complication following parotid gland surgery or trauma, results in unilateral sweating and flushing on the same side of the face during eating. Although harmless, it can substantially affect quality of life, and diagnosis may be challenging for clinicians unfamiliar with Frey’s syndrome. The primary mechanism of Frey’s syndrome involves abnormal regeneration: parasympathetic secretomotor fibers intended for the parotid gland reinnervate facial sweat glands and skin vessels, resulting in sweating and flushing rather than salivation. This case report outlines a typical presentation of auriculotemporal nerve syndrome in a young adult male after parotid trauma and surgery, which was confirmed by the starch-iodine test and successfully managed with intradermal botulinum toxin A injections. It covers key aspects of diagnosis, treatment, and follow-up care. Current management approaches are discussed, drawing on recent research and consensus recommendations.References
