Following right parotid gland surgery to remove a tumor, a 45-year-old woman found that saliva was constantly dripping from the right margin of her mouth. the surgery apparently damaged which nerve?
group of answer choices:
infraorbital nerve
buccal branch of trigeminal nerve
right temporal branch of facial nerve
marginal mandibular branch of facial nerve
mental nerve

The correct answer is C. Marginal mandibular branch of the facial nerve

Explanation:

The marginal mandibular branch of facial nerve connects in the lower lip and chin, this nerve affects movement and sensations in the bottom lip, the lower corner of the mouth and part of the chin. Due to this, it is common if this nerve is damaged it leads to distorted facial expression, especially a distorted smile, as well as drooling in the bottom lip.

According to this, it is likely the nerve that was damaged in the 45-year-old woman is the marginal mandibular branch of facial nerve because this nerve is the one related to the inner lip and the lower corner of the mouth, and therefore the one that would cause drooling or constant dripping of saliva from the right margin of her mouth in the case it is damaged.
