title: Perioral gustatory sweating: case report.
abstract: OBJECTIVE
  Presentation of a case of perioral Frey syndrome.
  
  
  METHODS
  Case report.
  
  
  METHODS
  A 72-year-old woman with hyperhidrosis around the mouth and chin.
  
  
  RESULTS
  This patient suffered from bilateral perioral gustatory sweating following a mandibular osteotomy; such a case has not previously been described. Possible pathophysiological hypotheses are discussed in relation to the anatomy and innervation of the salivary glands.
  
  
  CONCLUSIONS
  Perioral gustatory sweating is a rare complication of osteotomy.
