Auriculotemporal syndrome in Adult
Auriculotemporal syndrome often occurs after facial surgery or trauma. Up to 60% of patients can develop this syndrome after parotid gland surgery. Onset of symptoms can occur in the immediate postoperative period or may be delayed for several months after surgery.
The main sign is gustatory sweating, which is excessive sweating in the facial and periauricular areas after eating (especially foods that produce a strong salivary response such as sour, spicy, or salty foods). Flushing and erythema may also occur. Cases range from mild to severe.
Anticholinergics or antihidrotics are the first course of treatment.
