Bir doğuştan kraniyal disinnervasyon bozukluğu: Moebius sendromu

Moebius sendromu, diğer adıyla Moebius sekansı, doğuştan yüz ve göz sinirlerinde felç ile belirgin, ilerleyici olmayan bir kraniyal disinnervasyon bozukluğudur. Emmede zayıflık ve yüz felci nedeniyle izlenen, in vitro dölleme ile oluşan gebelik sonucu doğan, beş günlük kız hastaya iki taraflı pitoz ve dışa bakış kısıtlılığı, dilde sola kayma, dismorfik yüz görünümü, sol el parmak ve tırnaklarında hipoplazi bulguları ile birlikte Moebius sendromu tanısı konuldu. Bu sendroma üç, dört, beş, dokuz, 10 ve 12 gibi ek kraniyal sinir tutulumu, kol ve bacak gelişim anomalileri de eşlik edebilir. Etiolojide bir çok etmen öne sürülmekle beraber yardımcı üreme tekniklerine bağlı nadir olgular bildirilmiştir. Hastalarda beslenme güçlüğü ve aspirasyon sorunları süt çocukluğu döneminde karşılaşılan başlıca sorunlardır. Yüz felci ile doğan yenidoğan diğer kraniyal sinirler bakımından da ayrıntılı muayene edilmeli, ayırıcı tanıda Moebius sendromu ile birlikte diğer kraniyal disinnervasyon bozuklukları göz önünde bulundurulmalıdır.

A congenital cranial dysinnervation disorder: Möbius' syndrome

Möbius' syndrome, also known as Möbius' sequence, is a nonprogressive cranial dysinnervation disorder characterized by congenital facial and abducens nerve paralysis. Here, we report a 5-day-old girl who was conceived after in vitro fertilization with poor suck and facial paralysis. She had bilaterally ptosis and lateral gaze limitation, left-sided deviation of the tongue, dysmorphic face, hypoplastic fingers and finger nails on the left hand, and was diagnosed as having Möbius' syndrome. Involvement of other cranial nerves such as three, four, five, nine, 9 and 12, and limb malformations may accompany this syndrome. However, several factors have been proposed for the etiology, some rare cases have also been reported with artificial reproductive technologies. Feeding difficulties and aspiration are the main problems encountered in infancy. The other cranial nerves should be examined further in newborns who present with congenital facial palsy, and other cranial dysinnervation disorders should be considered in the differential diagnosis.
