What is Congenital Facial Paralysis?

Congenital facial paralysis (including Moebius Syndrome) is a rare form of facial paralysis that is detected in children at birth. To make the diagnosis, it is necessary to perform multiple studies, including a complete physical examination as it is necessary to rule out other malformations that may be associated with paralysis.

It is likely that a baby with congenital facial paralysis will present other disorders at birth such as: Microtia, cleft palate, deformity in their hands, arms or feet or have other mobility disorders in other areas of the face such as eyes or tongue.

Congenital paralysis can be divided into different categories:

– Unilateral or bilateral
– Traumatic or developmental
– Complete or incomplete

In addition to the problems present at birth, if congenital facial paralysis is not treated in time and does not resolve over time, this can result in problems tied to facial development such as speaking problems and issues with expressing emotions.

Causes of Facial Paralysis

Facial nerve disorders can present themselves in a range of functional and/or aesthetic manifestations. Such manifestations may include partial or complete lack of mobility of the facial muscles, abnormal movements (synkinesis), or facial spasms (involuntary movements). There can be several causes, among the most common are: Bell's palsy, an association with the herpes simplex virus, acoustic neuroma (intracranial tumor), trauma, or malignant tumors of the parotid gland.



Systems of Evaluation for Facial Paralysis

Whatever the cause, the consequences of facial paralysis can be devastating for the patient depending on the level or degree of facial or condition, so it is important during the clinical evaluation to determine the degree or severity through the use of various tools or scales, within these Some include House Brackman, E-Face, Sunnybrook, among others.

Anatomy of the Facial Nerve

The facial nerve looks like a telephone cord that contains about 10,000 fibers or small individual cables inside. Each small cable carries and brings information through nerve impulses to specific muscles of the face. This information that passes through the fibers informs the muscles and allows the expression of emotions such as laughter, crying, anger, sadness, and that is why this nerve is known as the nerve of facial expression.

Methods for Reconstructing the Facial Nerve

There are two key methods in facial nerve reconstruction: dynamic procedures and static procedures.

The objectives in facial resuscitation include achieving symmetry at rest, active facial movements and appropriate eye closure. Static procedures are those that seek to provide symmetry at rest, but do not provide function or mobility. They are procedures that are often used in combination with dynamic procedures or as complementary procedures to them, or alone when the patient cannot be a candidate for a dynamic procedure.

Dynamic procedures on the other hand, are known as all those procedures that seek to improve the mobility or function of the affected muscles, therefore they are what we always try to offer to the patient. Dynamic procedures include microsurgical procedures that include nerve grafts, nerve transfers or muscle replacements.

Moebius Syndrome

Moebius syndrome is a form of facial paralysis that may be present at birth. This syndrome includes facial paralysis associated with problems in the lateral mobility of the eyes. Babies born with the syndrome have problems controlling eye movements on one or both sides, as well as unilateral or bilateral facial paralysis.

Other problems that these patients may present are: inability to smile, frown, blink, suck, etc.

The management of Moebius Syndrome demands attention from a multidisciplinary group of experts that include: pediatric neurologist, ophthalmologist, rehabilitation, psychologist, speech therapist, otorhinolaryngologist, orthodontist, genetics, among others.


Treatment protocol for patients with congenital facial paralysis has changed in recent decades. Historically, patients were treated when they reached adulthood, with the advent of new microsurgical techniques and greater knowledge of these pathologies, management has been carried out at younger ages with the aim of improving their quality of life, directly having a positive psychological impact, boosting self-esteem henceforth improving social interaction, in addition to all the benefits obtained in the skeletal and muscular development of such patients.

Treatment must be tailored to the needs of each patient and the specific disorder they present. Patients with congenital lower lip paralysis have very limited problems that can be solved with chemical or surgical denervation of the healthy side to significantly improve facial symmetry without the need for very complex surgeries.

Patients with incomplete Moebius syndrome generally require two surgeries, the first is a nerve extension connected from the healthy side to carry synchronous nerve stimulation and the second operation is a gracilis muscle transplant AS activated by masticatory nerve and the previous extension. Such operations are performed around the age of 4 years, meanwhile patients with complete moebius are generally candidates for double muscle transplants activated by masticatory nerves only, due to the absence of the facial nerve.

Patients with congenital paralysis associated with the oculo-auriculo-vertebral spectrum may be candidates for nerve grafts or extensions from the healthy side to the affected side before the age of 2.

One of the most important factors in the treatment of children with congenital facial paralysis is the creation of a tailored plan in order to allow the patient to achieve the best results in terms of facial mobility and symmetry.
