A. Frey's syndrome, B. Conjunctivitis, C. Ophthalmia neonatorum, D. Abnormal facial nerve regeneration
D: Abnormal facial nerve regeneration
Answer: D: Abnormal facial nerve regeneration 
Explanation: Crocodile tear syndrome The mechanism appears to be a misdirection of regenerating gustatory fibers destined for the salivary glands, so that they become secretory fibers to the lacrimal gland and cause homolateral tearing while the patient is eating. A simple procedure, involving subtotal resection of the palpebral lobe of the involved lacrimal gland, proved to be an effective corrective measure in these cases.
