David, an aspiring baseball player, was struck on the left side of his face with a fastball pitch. He was not wearing a safety helmet. His zygomatic arch was crushed, as well as parts of the temporal bone. Following the accident and reconstructive surgery, he noted that his left lower eyelid was still drooping and the corner of his mouth sagged. What nerve damage did he sustain?
He suffered facial nerve damage on his left side. Due to the bone damage, branches to the eye and jaw were probably damaged. It is possible that the damage could be reversible if the nerves were not cut or crushed completely.
