Facial Paralysis in Long Island

Bell’s palsy is form of facial paralysis related to dysfunction of the facial nerve. Most cases are one-sided (unilateral) and the source is often unknown (idiopathic). It may be associated with Lyme disease as well as with the herpes simplex virus.

In the initial consultation, the degree of facial paralysis is first described. The facial nerve has five branches, which innervate specific muscle groups. Each component must be assessed and addressed to completely restore your natural appearance.

Forehead – The facial nerve (temporal branch) powers the frontalis muscle which is responsible for raising the eyebrow. Paralysis can lead to a drooping brow which may obstruct your vision. Treatment is aimed a static correction, where the eyebrow can be lifted and fixated in a higher position thereby relieving the obstruction and better improving the symmetry at rest.

Upper Eyelid – The facial nerve is responsible for closing the eyelid via the orbicularis oculi muscles. A different nerve maintains an open eyelid and balance is important in eyelid function. This is important for maintaining hydration to the eye itself and preventing corneal injury. Many patients naturally have whats known as the Bells Reflex where the eyeball rotates up when we sleep, which protects the cornea in the event the eyelids can not close. An exposed cornea can lead to blindness and a surgery aimed at protecting it is of paramount importance. A gold or platinum weight can be placed on the upper eyelid to help gravity assist in closing the eye when needed. This relatively simple operation can be performed as an outpatient or in the office setting.

Lower Eyelid – weakened tone of the lower eyelid muscles can lead to a droopy lower eyelid and increased exposure of the white part of the eye (sclera). Treatment is aimed at raising and tightening the lower lid so that there is less exposure of the eye. We accomplish this using midface lifting with orbital rim anchoring as well as canthoplasty techniques.

Lip and Cheek Animation – Facial expression is the key to social interaction, and the ability to smile and show emotion is what allows us to form healthy bonds. Facial paralysis can cause severe asymmetry, particularly upon smiling. Restoration of dynamic movement may require both nerve and muscle transfers.

Nerve grafts are obtained from a sensory nerve from the lower leg which can be approximated to the facial motor nerve on the unaffected side. We then can connect the newly “powered” nerve to the abnormal side and provide the electricity needed to move the previous “unpowered” muscles. Nerves regenerate at the rate of 1mm/day and several months may be required to see results.

When the muscles are without “power” for > 1 yr they often wither away and atrophy. New muscle must be placed to allow for dynamic function. The gracilis muscle from the thigh is often transferred to the face to restore the ability to smile in lieu of the dysfunctional facial muscles. This is often done 6-9 months after the initial nerve graft to allow for nerve regeneration.

Lower Lip – the facial nerve is responsible for moving the lower lip down during animation and paralysis often resembles a stroke-like appearance. Treatment is aimed at decreasing function of the “normal” lower lip using either surgical techniques aimed at removing the muscle or decreasing the function of the nerve branch. In addition, Botulinum toxin (Botox) can be injected in the office to improve symmetry, however the technique must be repeated every 6 months.
