Facial reanimation surgery

Facial reanimation surgery helps people with facial paralysis restore symmetry and function to their face. People with facial paralysis develop weakness or a complete lack of movement, usually in half of their face. The weakness creates an imbalance between the two sides of the face, known as asymmetry. This affects the way the face looks and functions, and sometimes causes discomfort or pain.

Facial paralysis can occur for many reasons. The most common causes are Bell's palsy and Ramsay Hunt syndrome. An injury, a stroke or a tumor also can cause facial nerve damage and loss of function. In infants, facial paralysis can happen due to injury during childbirth or during development. Not being able to move certain muscles of the face can make it hard to smile and show other emotions. Facial paralysis also may cause damage to eye health and vision due to not being able to voluntarily close the eye or blink. The paralysis also may cause a collapse of the nostril so that airflow is partially or completely blocked. This happens because the cheek muscles aren't able to pull the side of the nose toward the cheek. Another condition called synkinesis sometimes results following facial paralysis. In this condition, all the nerves in the face stimulate the muscles at the same time. This causes a "tug of war" effect. This can happen because the facial nerves didn't recover properly after paralysis. Synkinesis may affect speaking, chewing and swallowing. It also can cause the eye to close when moving the mouth or smiling. Depending on the cause, people with facial paralysis may recover without treatment over time. Sometimes nonsurgical treatments can help people regain symmetry and function. For example, physical therapy and onabotulinumtoxinA (Botox) injections can help people with synkinesis by relaxing some of the muscles. Facial nerve specialists can decide if early treatment is needed. Seeing a facial reanimation specialist is critical to get an evaluation and, in some cases, surgery. Some treatment options are only available soon after facial paralysis develops, so it's important to see a specialist early. Treatment is especially important if facial paralysis makes it hard to close the eye. Surgery can allow you to close your eye and protect it from becoming dry. If facial reanimation surgery is recommended, the procedure can give your face more balance and give you the ability to smile and regain other functions. The type of surgery you have depends on your symptoms. There are many techniques to restore movement to a paralyzed face. Some of these techniques include: Microsurgical facial nerve repair. Facial nerve grafting. Nerve transfer surgery. Muscle transfer surgery. Muscle transplant surgery, known as gracilis muscle facial reanimation. Face lifts, browlifts and other procedures that restore symmetry. Eyelid reanimation surgery to improve blinking and eyelid closure. People with synkinesis who have facial muscle tightness, spasms or contraction of all of the muscles in the face at once may benefit from: Injections of Botox, known as chemodenervation, to block nerve signals. Physical therapy including massaging and stretching, and neuromuscular retraining. Selective neurectomy, which involves cutting specific branches of the facial nerve. The goals of the operation are to relax some of the muscles in the face that feel tight, in addition to weakening muscles in the face that oppose the smile. Sometimes branches to the eyelids are cut to prevent the eyelids from closing when the person attempts to smile. Selective myectomy with terminal neurolysis, which involves dividing one or more of the muscles in the face.

As with any surgery, facial reanimation surgery carries some risk. The risks depend on the exact type of facial reanimation surgery. It's common to have temporary swelling, bruising and numbness in the area of the surgery that resolves with healing. Less common but possible risks include infection, a change in facial contour, nerve injury and blood collection under the skin, known as hematoma. If you have a nerve transfer, there is a risk that the nerve may not grow correctly. This can result in synkinesis. When a muscle is transplanted, there is a potential risk of lack of blood flow to the muscle, resulting in poor movement. However, these complication are rare. It may take several months before you see an improvement in facial paralysis. This is particularly true if you have nerve transfer or muscle transplant surgery. After these surgeries, it takes time for the nerve cells to grow after being connected. Almost always, people experience improvement after facial reanimation. However, you may find that the surgery doesn't completely restore function or that your face still has some imbalance. If this happens, your surgeon will likely find other options to improve your function. Some people require more procedures to get the best results. This can be due to a complication of the surgery or simply to enhance the outcome and achieve better symmetry and function. Facial reanimation surgery is specialized and personalized. It's best to talk about the risks and benefits with your surgeon and other members of your healthcare team before you have surgery.

Work with a surgeon and a healthcare team with a specialty in facial nerve and facial reanimation. This gives you access to advanced and comprehensive care. If you're seeking treatment for your child with facial paralysis, see a surgeon who specializes in this surgery in children. Because facial reanimation surgery is planned around your needs, your surgeon works to understand the cause of your facial paralysis. Your surgeon also asks how your facial paralysis impacts your life and what your treatment goals include. Using this information, along with a review of your health history, your surgeon works with you to develop a treatment plan. You'll likely have a comprehensive facial function exam. You may be asked to raise your eyebrows, close your eyes, smile and make other facial movements. Photos and videos of your face are taken, which can be compared to the results after surgery. Your healthcare team also looks for the cause and timing of the facial paralysis. If the cause is not known, you may need imaging tests such as computerized tomography (CT) scans or magnetic resonance imaging (MRI). If the cause is a tumor or trauma that can be treated, you'll likely receive treatment for the cause before considering facial reanimation surgery. Other tests can help your healthcare team determine how much nerve injury is present. Tests also may reveal if nerve damage is likely to improve without surgery. These tests include electromyography (EMG) and electroneurography (ENoG). You may meet with a physical therapist. The physical therapist looks at the movement you currently have and teaches you techniques of stretching, massaging and strengthening. The treatment plan is tailored to your individual needs. You also may see other specialists such as a neurologist and ophthalmologist. These experts work together with your surgeon to create a treatment plan. Before deciding on surgery, your healthcare team may have you try other treatments such as Botox injections. If you have a child with facial paralysis, the timing of surgery is important. Your surgeon may recommend waiting for your child to grow and develop before having facial reanimation surgery. It's important to talk to your surgeon about the goals of surgery and whether more than one surgery is needed. Be sure that you understand the potential benefits and risks of the surgery, and the care you'll need after surgery.
