Crocodile tears are seen in-
**Core Concept**
Crocodile tears syndrome, also known as Bogorad's syndrome, is a rare neurological disorder characterized by the involuntary lacrimation (tearing) during meals or eating. This phenomenon occurs due to aberrant regeneration of the nerve fibers between the facial nerve (cranial nerve VII) and the glossopharyngeal nerve (cranial nerve IX) following damage to the facial nerve.
**Why the Correct Answer is Right**
During the healing process, the nerve fibers of the facial nerve may incorrectly reconnect with the nerve fibers of the glossopharyngeal nerve, which controls the parasympathetic innervation of the lacrimal gland. As a result, the lacrimal gland receives inappropriate parasympathetic stimulation, leading to excessive tearing during meals or eating. This condition is often seen in patients who have had a facial nerve injury or surgery, particularly those with Bell's palsy.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the condition of crocodile tears syndrome.
**Option B:** While Bell's palsy is a condition that affects the facial nerve, it is not directly related to the development of crocodile tears syndrome.
**Option C:** This option is incorrect as it does not describe a condition related to the phenomenon of crocodile tears.
**Clinical Pearl / High-Yield Fact**
Crocodile tears syndrome is a rare but important condition to recognize, as it can be a complication of facial nerve damage or surgery. The condition is often associated with aberrant regeneration of nerve fibers between the facial and glossopharyngeal nerves.
**Correct Answer: C.
