Clinical Characteristics and Outcomes of Möbius Syndrome in a Children's Hospital

Abstract

BackgroundMöbius syndrome is a congenital disorder with facial and abducens palsy. Although a few case series studies have examined comorbid conditions in Möbius syndrome, follow-up and outcome data are sparse. ObjectivesTo examine the clinical characteristics and outcomes of Möbius syndrome. MethodsClinical data were reviewed for 10 patients. Neonatal history, neurological examination, comorbid anomalies, medical home care, outcomes, and neuroimaging were summarized. ResultsThe patients' mean age was 7.3 ± 6.2 years. On neurological examination, absent blink reflex, jaw ankylosis, absent gag reflex, and tongue atrophy were frequently observed. Poland anomaly and clubfoot were present in three and six patients, respectively. Specific therapies required for patients included medical home care (six patients), suction apparatus (six), tube feeding (five), gastrostomy (two), tracheostomy (three), oxygen therapy (three), and home ventilator (two). Punctate calcification in the brainstem was observed in four patients. Pontine and medulla hypoplasia were detected on the basis of anteroposterior diameter in four and seven patients, respectively. Two patients had congenital hydrocephalus with aqueductal stenosis. Global developmental delay occurred in five patients. Three patients died. ConclusionThe rate of both the use of home medical devices and death was high in our patients. Möbius syndrome is extremely diverse, not only in clinical manifestation, but also outcome. Early multidisciplinary intervention is important to ensure an optimal outcome. Aqueductal stenosis is an occasional comorbid anomaly resulting from midbrain abnormality.
