Facial asymmetry in facial paralysis, and the mouth shifting to the healthy side while talking or crying are the most striking findings. There is a decrease in facial expressions and movements. Various symptoms can be seen, including inability to close the eye unilaterally, decrease in tears, inability to wrinkle the forehead, inactivity of the nose wings while breathing, inability to whistle, decrease in salivary secretion, and taste disturbance.
One of the most common complications after facial palsy is synkinesis. Synkinesis means ‘involuntary movement’. It occurs in the form of spontaneous movement of unwanted muscle groups in facial movements as a result of abnormal regeneration of the facial nerve after Bell’s palsy or facial nerve cut and repair. For example; like the spontaneous closing of the eyelid during a smile.
One of the most common complications after facial paralysis is crocodile tears. Botox application is a good treatment option in eliminating these complications. We apply Botulinum Toxin for treatment in managing involuntary muscle movements and controlling tears.
