title: Successful ex utero intrapartum treatment procedure for prenatally diagnosed severe micrognathia: a case report.
abstract: We present a case of fetal severe micrognathia in which successful airway stabilization was achieved by an ex utero intrapartum treatment procedure. In this case, it was anticipated that the infant would have a vulnerable airway at birth based on in utero sonographic findings, including an extremely hypoplastic jaw, worsening polyhydramnios and absence of stomach visualization. Early sonographic recognition was helpful in preparing the parents and physicians for the possibility of airway emergencies during the perinatal period. When a severely hypoplastic mandible accompanied by polyhydramnios and absent stomach visualization is noted on ultrasound, clinicians should consider the indication for ex utero intrapartum treatment. A multidisciplinary team with technically skilled medical providers should be coordinated to perform the procedure.
