Facial Nerve Paralysis

Seeing a neurologist is advisable when sudden weakness appears on one side of the face, since this is the specialist who studies the function of the facial nerve and rules out other causes. Facial nerve paralysis is the total or partial loss of movement of the muscles on one side of the face, due to an alteration of this nerve.

Common symptoms: difficulty closing one eye, drooping of the corner of the mouth, trouble smiling or raising the eyebrow on the affected side.

Common causes: it can be caused by inflammation of the nerve, infections, trauma, or neurological processes.

When should you see a doctor? With facial weakness that appears suddenly, a prompt evaluation is advisable; depending on the case, the otolaryngologist or the oral and maxillofacial surgeon may also get involved. Talk with a professional to understand what is happening.
