How is Facial Paralysis Treated?
Treatment depends on which parts of the face are experiencing paralysis, and what result is needed or desired. Surgical and non-surgical treatments may be offered.
Non-Surgical Treatments
Non-surgical treatments help correct movement patterns in the face and can include:
-
Physical therapy, including facial movement exercises.
- Botulinum toxin (Botox) injections to relax the facial muscles.
- Steroid medicine to reduce inflammation and limit nerve damage.
Surgical Treatments
Surgical treatments include:
To restore the ability to blink:
Some children can’t completely close their eye. This can lead to dry eye, which can cause problems with vision and the overall health of the eye. To treat this problem, we can surgically insert a gold weight in the eyelid. This causes the eyelid to close because of gravity. The muscle that opens the eyelid will still work. This results in fewer problems with dry eye and helps prevent eye injuries.
To restore a smile:
When there is paralysis on one side of the face, the smile can be asymmetrical or not the same on both sides of the face. If the paralysis is due to trauma or surgery, sometimes it’s possible to do a nerve graft from the other side of the face. This surgery can be done at any age when the paralysis is due to injury.
In this surgery, we take a healthy nerve from the non-paralyzed side of the face and connect it to the other side of the face using a graft from the leg. The healthy nerve is connected to the paralyzed facial muscle. As the nerve graft heals, muscle function slowly returns. It can take anywhere from 6-12 months to see results after nerve grafting. If paralysis has been present for more than two years it is usually not possible for the muscle to regain function, and a muscle transfer is usually necessary.
- Free functional gracilis muscle transfer
In some cases of facial paralysis, the muscle no longer functions. In these cases, we can perform a muscle transfer surgery. You may also hear this called facial reanimation. This involves removing a muscle from the leg (the gracilis muscle, which is in the inner thigh) and transferring it to the face. The muscle needs to be connected to a working nerve. This can be from a cross-face nerve graft in another surgery or the nerve that controls chewing in the same surgery. As the repair heals, the muscle regains function, restoring movement in the face. It is a complex surgery with good success rates.
It can take from four to six months to see results after this surgery. Children must be at least age 10 to have this surgery.
- Weakening of the lip depressors
Some kids have problems with paralysis in the lower lip. In these cases, the muscles in the functional side of the lip appear to work too much. To treat this, we start by giving botulinum toxin (Botox) injections to weaken the normal side of the lip. This can make a child’s smile symmetrical again.
If the Botox injections make a big difference, we can do a surgery to divide the muscles inside the mouth. This permanently weakens the non-paralyzed side of the mouth. The result is a more balanced smile.
