Facial paralysis, facial deviation, and mouth distortion are other names that are also the most visible signs of 7th nerve palsy.

The 7th nerve is the nerve that controls the movements of the facial muscles. Peripheral 7th cranial nerve palsy (peripheral facial palsy) occurs when the VII nerve is damaged or broken, leading to partial or complete loss of movement of a muscle group in a whole or half of the face.

7th nerve palsy not only brings difficulties and inconveniences in life and affects health but also destroys the aesthetics of the patient’s face.

The signs of peripheral VII nerve palsy

The patient who suffers from this disease can be paralyzed on the right side or on the left side of the face. With the following symptoms:

  • The face is stiff, sagging, mouth twisted to one side. The patient can easily spit food or water out.

The causes of 7th nerve palsy

Before distributing to all facial muscle groups, nerve VII has a very complicated path. Therefore, the cause of damaged peripheral nerve VII leading to facial paralysis can originate from different locations including pons, from VII nerve in the cerebellopontine angle, petrous bone, parotid gland.

  • Cold infection: this is the cause of 80% of the 7th nerve palsy cases, which occurs after a sudden cold or overnight.
  • Physical damage: occurs after a collision, an injury that causes damage to the petrous bone area, or after surgery in the ear mastoid area… 7th nerve paralysis in children can be caused by trauma during birth.
  • Inflammation: caused by viruses, typically Ramsay Hunt syndrome caused by varicella zoster virus.

The most common diagnosis for 7th nerve palsy is through clinical symptoms such as facial paralysis, mouth distortion, eyelids cannot close, drooping eyelids, taste disturbances, ear discharge, decreased tear secretions,…
