Frey's syndrome results from injury to:

  1. Spleen nerve
  2. Auriculotemporal nerve
  3. Cranial nerve
  4. Polycythemia
Explanation

Answer: B - Frey's syndrome results from injury to the auriculotemporal nerve. The damaged nerve, in effort to repair, joins with sympathetic fibers that lead to sweating, flushing, and warmth to temporal areas. Minor's starch-iodine test can be use to determine sweating preauricular area. The condition can be treated with local atropine injections or scopolamine creams.
