**Core Concept**
Frey's Syndrome, also known as gustatory sweating or auriculotemporal syndrome, is a rare neurological disorder characterized by excessive sweating (hyperhidrosis) and flushing of the skin in response to stimuli that normally cause salivation, such as the sight, smell, or taste of food. This condition typically occurs after damage to the parotid gland or its surrounding nerves.

**Why the Correct Answer is Right**
Frey's Syndrome is caused by the aberrant regeneration of parasympathetic nerve fibers of the auriculotemporal nerve, which carries secretory fibers from the otic ganglion to the parotid gland. When these fibers misdirect their growth, they may aberrantly synapse with sympathetic nerve endings, leading to the characteristic symptoms of gustatory sweating. The condition is more likely to occur after parotidectomy (surgical removal of the parotid gland) than enucleation (removal of a tumor or lesion within the gland), as the latter is a less invasive procedure that preserves the surrounding nerve tissue.

**Why Each Wrong Option is Incorrect**
**Option A:** Gustatory sweating is indeed a hallmark symptom of Frey's Syndrome, making this statement true and not the exception.

**Option B:** Aberrant misdirection of parasympathetic fibers of the auriculotemporal nerve is the underlying pathophysiological mechanism of Frey's Syndrome, making this statement true and not the exception.

**Option C:** Botulinum toxin is indeed one of the treatment options for Frey's Syndrome, as it can temporarily block the release of acetylcholine at the neuromuscular junction and reduce sweating. This statement is true and not the exception.

**Clinical Pearl / High-Yield Fact**
Frey's Syndrome is often misdiagnosed as a recurrence of parotitis (inflammation of the parotid gland) or as a side effect of radiation therapy. A key clinical clue is the presence of gustatory sweating, which is typically absent in these other conditions.

**✓ Correct Answer: D. Less chances with enucleation than parotidectomy**
