Varying definitions of Moebius syndrome exist in the medical literature.

To improve consistency in diagnosis, clinical criteria for a diagnosis of Moebius syndrome were established by an international group of experts at a Moebius Syndrome Foundation research conference in Both criteria must be present for a diagnosis of Moebius syndrome.

These two symptoms may be due to impairment in the facial nerve cranial nerve 7 and the abducens nerve cranial nerve 6respectively. In addition to the above strict clinical criteria, additional signs or symptoms may also be present, including, but not limited to:.

Moebius syndrome was originally described by German ophthalmologist Alfred Graefe inbut is named for German neurologist Paul Julius Moebius, who reported features of this condition in The incidence of Moebius syndrome is roughly 2 to 20 cases per million births.

The condition occurs in all ethnicities. There is no gender bias males and females are affected equally. In very rare cases, a change in specific genes may be causative of Moebius syndrome.

Additionally, there are several other separate conditions with similarities to Moebius syndrome that have identified genetic etiologies. References: 1 Miller, G. Neurological disorders.

Read PDF. It is commonly associated with facial paralysis or weakness. People born with Moebius syndrome often have a small chin, small mouth and short tongue. They may also have an abnormal opening at the roof of the mouth. These issues may cause speech problems, along with missing or misaligned teeth.

It may make it difficult for a person to completely close his or her eyes when blinking or sleeping as well. Moebius syndrome is generally diagnosed based on two clinical criteria: the appearance of non-progressive congenital facial weakness and an inability to move one or both eyes away from the nose.

Also, an individual dealing with Moebius syndrome may display one or more of the following symptoms:. Research shows Moebius syndrome occurs in anywhere from two to 20 cases per million births. Moebius syndrome also affects individuals of all ethnicities, and it has no gender bias. There is no surefire cause of Moebius syndrome.

However, research indicates Moebius syndrome may occur due to a combination of environmental and genetic factors. Some researchers have also discovered specific genes may be related to Moebius syndrome. Various medications taken during pregnancy and drug abuse may also cause Moebius syndrome. Most Moebius syndrome cases are sporadic, and as such, occur in people with no family history of the disorder. Researchers continue to study Moebius syndrome to determine if genetics are the primary cause for the condition.

Coronavirus (COVID-19)

To date, researchers have found changes in certain genes may cause Moebius syndrome. But there is still no proof that Moebius syndrome is a genetic condition.

Moebius syndrome treatment is usually performed on children before they enter school. Additionally, since each Moebius syndrome patient has a unique presentation of the condition, and treatment is specifically tailored to the patient. Azizzadeh allocates significant time and resources to learn about a Moebius syndrome patient and his or her facial paralysis symptoms.

He then develops a personalized treatment plan for a patient. By doing so, Dr. Azizzadeh ensures a patient can achieve the best-possible treatment results.

Many Moebius syndrome patients are unable to smile or frown or make lateral eye movements.

As a result, Moebius syndrome treatments are designed to help patients improve facial reanimation.Alternative titles; symbols. Cytogenetic location: 13q The facial nerve cranial nerve VII and abducens nerve CN VI are most frequently involved, but other cranial nerves may be involved as well. Other variable features include orofacial dysmorphism and limb malformations.

Mental retardation has been reported in a subset of patients. Most cases of Moebius syndrome are sporadic, but familial occurrence has been reported Verzijl et al. The definition of and diagnostic criteria for Moebius syndrome have been controversial and problematic. The syndrome has most frequently been confused with hereditary congenital facial paresis HCFP; seewhich is restricted to involvement of the facial nerve and no other abnormalities.

Verzijl et al. Moebius syndrome was defined at the Moebius Syndrome Foundation Research Conference in as congenital, nonprogressive facial weakness with limited abduction of one or both eyes. Additional features can include hearing loss and other cranial nerve dysfunction, as well as motor, orofacial, musculoskeletal, neurodevelopmental, and social problems summary by Webb et al.

Kumar provided a review of Moebius syndrome, which was critiqued by Lipson et al. Briegel provided a review of Moebius sequence with special emphasis on neuropsychiatric findings. Congenital nonprogressive facial and abducens palsy was first described by Graefe and Moebius Harvey noted that Thomas had described the disorder in Congenital paralysis of the sixth and seventh cranial nerves was observed in multiple members of families by Wilbrand and Saenger Sprofkin and Hillman described a patient with arthrogryposis and Moebius syndrome who had a sib with arthrogryposis only.

Hanissian et al. The facial nerves were small or absent at autopsy in both cases. Steigner et al. Some of these patients may have had isolated hereditary congenital facial paresis. Wishnick et al. In 9 others, digital anomalies occurred apparently without cranial nerve involvement.

EMG studies confirmed the involvement of the cranial nerves. Wishnick reported that she had no further information on this family and had seen no similar cases.

Stabile et al. His brother had left convergent strabismus and mental retardation.The earliest sign is the inability of the newborn to suckle, with an expressionless face, and drooling. Paralysis may be unilateral or bilateral. As individuals grow older, the most conspicuous signs are an inability to close their mouths or smile. Inability to blink may lead to corneal abrasions.

Etiology is multifactorial, and several theories have been proposed, with the most supported theory being of a transient ischemic or hypoxic insult to the fetus.

Infectious and genetic etiologies have also been proposed. Additional brainstem involvement is also common and may include other cranial nerves as well as the musculoskeletal system. Grading schemes have been proposed which include additional manifestations e.

CLUFT cranial nerve, lower limb, upper limb, face, and thorax. MRI findings are those of brainstem hypoplasia pons and medulla with straightening of the floor of the fourth ventricle as a result of absence of the facial colliculus.

Cerebellar hypoplasia, calcification of the pons in the region of the abducens nuclei and even absence of the middle cerebellar peduncles have been reported. Various plastic surgery procedures can be performed to attempt to recover facial muscles function. For example, microvascular transfer of a gracilis muscle to the face.

The abducens nerves are also not identified, although this can be difficult to assess given the size of the infant.

There is minor flattening of the dorsal medulla however the cerebellar peduncles are normal. Myelination is normal for age.

When present, the facial nerve is located superior and anterior to the vestibulocochlear nerve at the cerebellopontine angle and the internal auditory canal.

Image 1: Normal right vestibulocochlear nerve within the cerebellopontine angle. The loop of the anterior inferior cerebellar artery is seen anteriorly however the facial nerve is not present. Image 2: Within the internal auditory canal, the green arrows represent the superior and inferior vestibular nerves and the blue arrow the cochlear nerve.

The facial nerve is absent. The facial nerve should be located superior to the cochlear nerve and falciform crest, anterior to Bill's bar. Image 3: Normal roots of the trigeminal nerves within the prepontine cistern. The etiology remains poorly elucidated however vascular insult and various drugs have been implicated.

Full screen case with hidden diagnosis.Moebius syndrome is a rare neurological condition that primarily affects the muscles that control facial expression and eye movement. The signs and symptoms of this condition are present from birth. Weakness or paralysis of the facial muscles is one of the most common features of Moebius syndrome.

Affected individuals lack facial expressions; they cannot smile, frown, or raise their eyebrows. The muscle weakness also causes problems with feeding that become apparent in early infancy. Many people with Moebius syndrome are born with a small chin micrognathia and a small mouth microstomia with a short or unusually shaped tongue. The roof of the mouth may have an abnormal opening cleft palate or be high and arched.

These abnormalities contribute to problems with speech, which occur in many children with Moebius syndrome. Dental abnormalities, including missing and misaligned teethare also common. Moebius syndrome also affects muscles that control back-and-forth eye movement.

Affected individuals must move their head from side to side to read or follow the movement of objects.

People with this disorder have difficulty making eye contact, and their eyes may not look in the same direction strabismus. Additionally, the eyelids may not close completely when blinking or sleeping, which can result in dry or irritated eyes. Other features of Moebius syndrome can include bone abnormalities in the hands and feet, weak muscle tone hypotoniaand hearing loss. Affected children often experience delayed development of motor skills such as crawling and walkingalthough most eventually acquire these skills.

Some research studies have suggested that children with Moebius syndrome are more likely than unaffected children to have characteristics of autism spectrum disorders, which are a group of conditions characterized by impaired communication and social interaction.

However, recent studies have questioned this association. Because people with Moebius syndrome have difficulty with eye contact and speech due to their physical differences, autism spectrum disorders can be difficult to diagnose in these individuals. Moebius syndrome may also be associated with a somewhat increased risk of intellectual disability; however, most affected individuals have normal intelligence.

The exact incidence of Moebius syndrome is unknown. Researchers estimate that the condition affects 1 in 50, to 1 innewborns. The causes of Moebius syndrome are unknown, although the condition probably results from a combination of environmental and genetic factors. Researchers are working to identify and describe specific genes related to this condition. The disorder appears to be associated with changes in particular regions of chromosomes 3, 10, or 13 in some families.
