cranial nerve damage with face lacerations?
if a person had deep face lacerations what cranial nerves would be damaged?
depends on where the laceration is. but CN VII (facial nerve) is more than likely. CN VII gives sensation to the scalp all the way down to the neck, along with face muscles giving expressions. this nerve tracks out from the parotid gland (just in front of your ears) out the middle of it and branches five ways thru out the face.
if the laceration is really deep and broke bones, say a jaw fracture, you could damage CN V (third branch), which gives sensation to your lower teeth. CN V (second branch) innervates the upper teeth, this would slice, if you broke your upper face.
hope it didn't happen to you.
