Answer:
Parotid fistula is an uncommon problem. The clinician should have patience in treating this transient but prolonged problem. Periodic probing of the wound to release fluid is often all that is needed before the fistula closes. If the fistula persists for several months, surgical correction is required.
Gustatory sweating, Frey’s syndrome, consists of sweating and flushing of the skin over the parotid area during eating. It is thought to be due to aberrant innervation of the cutaneous sweat glands by the regenerating parasympathetic secretory fibers that once supplied the parotid. This problem may be annnyoing to patients. Use of antiperspirants is usually all that is required. However, surgical interruption of the secretory fibers by performing a tympanic neurectomy and excising chordae tympani can be attempted if the problem persists.
