Correct Answer � A Explanation

Answer A. Auriculotemporal Nerve

Frey’s syndrome

• Frey’s syndrome (also known as Baillarger’s syndrome, Dupuy’s syndrome, auriculotemporal syndrome, or Frey-Baillarger syndrome) is a rare neurological disorder resulting from damage to or near the parotid glands responsible for making saliva, and from damage to the auriculotemporal nerve often from surgery.
• The symptoms of Frey’s syndrome are redness and sweating on the cheek area adjacent to the ear.

Signs and symptoms

• Signs and symptoms include erythema (redness/flushing) and sweating in the cutaneous distribution of the auriculotemporal nerve, usually in response to gustatory stimuli. 

Causes

• Frey’s syndrome often results as a side effect of surgeries of or near the parotid gland or due to injury to the auriculotemporal nerve, which passes through the parotid gland in the early part of its course.
