Agnathia literally means absence or severe dysplasia of the mandible. It is a rare expression of first brachial arch malformation. In the present case was detected polyhydramnios and the fetus demonstrated mandibular dysplasia on prenatal ultrasound diagnosis at 30 weeks of gestation. There were no signs of holoprosencephaly on prenatal MRI. At 36 weeks of gestation, cesarean section was performed. Immediately after birth the infant was tracheostomized. She has survived to infancy with tracheotomy.
Key words:
agnathia, tracheostomy, polyhydramnios
