Test #4 - Neural deficit from gunshot

What neural deficit may be experienced from a small caliber gunshot wound to the head affecting the vestibulocochlear and facial nerves?

Vestibulocochlear: conducts impulses of hearing & equilibrium from inner ear.

Facial:
sensory function - taste from anterior 2/3 of tongue
somatic motor function - innervates muscles of facial expression and other muscles of the facial region
parasympathetic motor- innervates the lacrimal (tear) gland, submandibular and sublingual salivary glands
