Introduction
Moebius syndrome (MBS) or Moebius sequence [11Pedersen LK,
Maimburg RD, Hertz JM, et al. Moebius sequence -a multidisciplinary
clinical approach. Orphanet J Rare Dis . 2017;12(1):4. Published
2017 Jan 6. doi:10.1186/s13023-016-0559-z.] is a rare,
non-progressive, neurological congenital defect characterized by uni- or
bilateral congenital 7th and 6thcranial nerve paralysis and less commonly abnormalities of other cranial
nerves (CN) III, IV and IX-XII, craniofacial, odontological,
ophthalmological and orthopedic anomalies.
Facial diplegia, gaze palsy, dysphagia and breathing difficulties are
associated with MBS. Approximately 90% of the newborns present with
airway obstruction from associated craniofacial anomalies [222Cuestas G, Quiroga V, Zanetta A, Giménez E. Manejo de la vía aérea en
el neonato con síndrome de Moebius. An Pediatr (Barc).
2019;91:264–267.].
The reported incidence of MBS is 1 case per 250,000 live births, with no
sex variation. Prognosis is strictly dependant on the degree of
patient’s deficits but, with early recognition of the disease, there is
hope for average developmental results by 5 years of age [33Picciolini

Management of MBS patients remain supportive and symptomatic, with main
focus on restoring normal breathing and feeding functions when needed
and long term psychological, physical, occupational and speech therapy.
We present the case of an infant with MBS who presented to our hospital
with breathing and feeding difficulties and discuss the challenges
around the diagnosis and treatment of such a patient. Written informed
consent from the child’s parents and approval from the Hospital’s Ethics
Board were obtained.
