Facial Nerve Palsy
A facial nerve palsy is caused when the vernes that feed one side of the face become damaged, resulting in less control over the muscles in the affected area. This normally leads to a ‘drop’ on the side of the face affected, with difficulty smiling and closing the eyes. In partial paralysis, only the lower half of the face is affected, but in full paralysis it is the whole side of the face. There are many potential causes of the condition, including the herpes virus that normally results in cold sores. Although symtoms can improve on their own, steroids can be used to reduce the swelling that might be restricting the nerve, and in serious cases surgery can be attempted to graft a replacement nerve on to the affected area.
