Micrognathism and Pierre Robin Sequence

Seen in approximately one in 8,500 live births, micrognathia and Pierre Robin sequence are related conditions in which the jaw or chin is smaller than normal, causing breathing and feeding problems at birth. Diagnosed through level II ultrasound, fetal MRI, echocardiogram and amniocentesis, these conditions cannot be treated with fetal intervention and may require surgery at birth.
