"Crocodile tears syndrome" (spontaneous lacrimation during eating because of misdirection of regenerating autonomic nerve fibers) occurs after injury to which of the following nerves?,
"Crocodile tears syndrome" (lacrimation during eating) is caused by a lesion of the facial nerve proximal to the geniculate ganglion. This happens due to misdirection of regenerating parasympathetic fibers, which formerly innervated the salivary glands, to the lacrimal glands.
Facial nerve proximal to the geniculate ganglion
