How facial reanimation works
Facial reanimation surgery can involve different approaches depending on the cause of paralysis and your individual needs. Some treatments restore facial symmetry at rest (static reanimation), while others bring back movement and expression (dynamic reanimation). In some cases, nonsurgical treatments or physical therapy may also help.
Nerve transfers reroute healthy nerves from another part of the body, like the masseteric nerve (responsible for chewing) or the hypoglossal nerve (responsible for tongue movement), to the facial nerve branches on the paralyzed side of the face. This helps restore tone and movement, including smiling or closing the eyes.
We offer several types of nerve transfer procedures, including:
- Masseteric nerve transfer (5-7)
- Hypoglossal nerve transfer (12-7)
In nerve grafting, a healthy nerve from another part of the body is transplanted to repair or replace a damaged facial nerve. This creates a new pathway for nerve signals, helping to restore movement and expression.
This advanced procedure moves a small muscle from the inner thigh to the face, along with its nerve and blood vessels. Once healed, the transplanted muscle can contract and recreate a smile.
Types of gracilis free muscle transfers include:
- Gracilis by masseteric nerve
- Gracilis by cross-facial nerve graft
- Dually innervated gracilis free flap
- Multi-vector gracilis free flap
These procedures can be completed with the patient awake without the need for general anesthesia or fasting. These are usually completed in less than an hour and are very well tolerated by patients.
- Intraoral myectomies: These procedures remove small muscles that negatively affect the shape and contour of the smile. A common example is the depressor anguli oris (DAO) myectomy, which can improve natural movement of the smile that is less restricted.
- Eye treatments: Facial paralysis often affects both eyelids which can inhibit eye closure (lagophthalmos, ectropion). Options like low-profile platinum eyelid weights, lower eyelid tightening, or functional eyelid surgery (blepharoplasty) can protect vision and improve comfort.
- Botulinum toxin (Botox): Injections can reduce unwanted facial movements (synkinesis) that sometimes develop after paralysis. By relaxing overactive muscles, Botox helps improve facial balance and symmetry.
- Physical therapy: Rehabilitation plays an important role in recovery. Specialized physical therapy helps retrain facial muscles, build strength, and support long-term results after surgery.
