Facial paralysis: symptoms

Since facial paralysis takes different forms (partial or total, temporary or definitive), resulting from various causes, the symptoms are also different depending on the origin of the pathology.

Symptoms of peripheral facial palsy

Peripheral facial palsy concerns only half of the face. Exceptionally, it can affect both facial nerves (bilateral facial palsy).

As a general rule, during peripheral facial paralysis, the paralyzed side of the face remains frozen. This results in an asymmetry of the face with the affected side:

  • Wrinkles of forehead faded
  • The sagging eyebrow
  • The eye can not close: the upper eyelid stays up and the lower eyelid falls.
  • Disappearance of the fold that goes from the nose to the mouth
  • The commissure of the lip goes down
  • The features deviated to the healthy side
  • A difficulty in speech
  • Discomfort with chewing, sometimes cheek bite

Depending on where the nerve is touched, there may also be a lack of tears or dryness of the nose, increased sensitivity to noise, and a change or absence of taste on a portion of the tongue. On the healthy side, we can see hyperactivity of the expression muscles.

In facial paralysis to frigate one can witness a numbness of the face.

Symptoms of central facial paralysis

In the case of central facial paralysis, resulting from a brain tumor or stroke, only the lower part of the face (cheeks, mouth) is affected.

By the way, that's how we define stroke with the acronym VITE. V for "sagging face".

Central facial paralysis is then accompanied by other signs, such as an altered vision like diplopia (see double) for example, hemiplegia (paralysis of half of the body) or other symptoms.
