What is another name for gustatory sweating?

• A. Frey's syndrome
• B. Chaudhary's phenomenon
• C. Parotid hyperplasia
• D. Brun's syndrome

Answer: (A)

Gustatory sweating is commonly referred to as Frey's syndrome. This condition typically occurs following injury to the parotid gland or its innervation, leading to an abnormal connection between the nerves that control sweating and those responsible for salivation. When a person eats, the parasympathetic nerves intended for salivation mistakenly stimulate sweat glands in the area, causing sweating on the face, particularly near the cheek, rather than the expected salivation in the mouth.

Frey's syndrome highlights the importance of understanding the neurophysiology associated with cranial nerve function and its potential complications after maxillofacial surgery or trauma. The other terms listed do not accurately describe gustatory sweating, and thus the association with Frey's syndrome is the most recognized and established terminology in medical literature.
