This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: ENT
Following a parotid surgery, the patient developed sweating over the side of his face and over the cheek while eating. This is due to abnormal connections that develop between parasympathetic secretomotor fibres in the auriculotemporal nerve with which of the other nerves? 
Select and explain. 
A. Glossopharyngeal nerve, B. Great auricular nerve, C. Facial nerve, D. Buccal nerve
B: Great auricular nerve
Answer: B: Great auricular nerve 
Explanation: Auriculotemporal nerve normally carries parasympathetic fibers to the parotid gland and is severed during injury to parotid gland. Cause of gustatory sweating in freys syndrome is due to the faulty regeneration of fibers after injury to the auriculotemporal nerves in which secretomotor fibers are connected to the sympathetic fibers inside it. Sometimes the secretomotor fibers are connected to the sympathetic fibers in the greater auricular nerve which result in sweating over the skin covering the parotid gland and the angle of the mandible during eating.
