Möbius syndrome

Möbius syndrome is a rare congenital disease characterized by facial and abducens nerve palsy. Children are unable to smile, frown, suck, grimace, blink their eyes, and to move their eyes laterally. The aim of this study was to analyze the diagnosis and treatment of this disease. Maxillofacial examination reveals: facial diplegia, retrognathism, palatine and dental malformations. Möbius syndrome is usually associated with multiple cranial nerve involvement, limb or orofacial malformation, and Poland syndrome. Although the pathogenesis of the syndrome is unclear, a number of mechanisms have been suggested including vascular and genetic hypotheses. Symptomatic treatment is used to manage this syndrome. The diagnosis of Möbius syndrome may be difficult in some patients with atypical signs of facial diplegia and other cranial nerve palsies, it requires a multidisciplinary approach.
