Dm. Sherer et P. Spafford, PRENATAL SONOGRAPHIC EVIDENCE SUPPORTING AN IN-UTERO DEVELOPMENTAL ETIOLOGY OF MOBIUS SEQUENCE, American journal of perinatology, 11(2), 1994, pp. 157-159
Mobius sequence features masklike facies with sixth and seventh nerve
palsy and frequently micrognathia thought to result from a neuromuscul
ar deficiency in early movement of the mandible. Failure to thrive in
infancy is commonly due to feeding and aspiration difficulties. We pre
sent the first description of prenatal sonographic findings associated
with this lesion, which also support an in utero developmental etiolo
gy of this rare condition.
