A Case of the Ex Utero Intrapartum Treatment Procedure for Fetal Giant Fourth Branchial Cleft Cyst / 대한이비인후과학회지

ABSTRACT

Large neck masses in the fetus can result in neonatal hypoxia with airway obstruction during a delivery. The ex-utero intrapartum treatment (EXIT) is a procedure that would be helpful in safely securing a fetal airway when the maternal-fetal circulation is being obstructed. Branchial cleft cyst (BCC) is a relatively common congenital malformation in the neck, however, the fourth BCC is very rare. Herein, we present a case of a giant fourth BCC, which was prenatally detected on ultrasound and safely surgically treated to secure an airway with EXIT procedure during the delivery.
