Our facial nerves allow us to show emotions through the ability to move our features, such as our eyebrows, nose, or lips.
Synkinesis and muscle tightness
One frequent complaint from patients is the tightness in the muscles that can result from facial nerve paralysis, within the area of one’s neck in particular. This can be treated with Botox to alleviate the tightness.
Furthermore, while subtle, it is not uncommon for that inadvertent act of squinting the eye while smiling to be found in patients with facial nerve paralysis.
