AbstractCongenital oral and neck masses are associated with a high perinatal mortality and morbidity secondary to airway obstruction due to a mass effect of the tumor with subsequent neonatal asphyxia and/or neonatal death. In 1997, the Ex Utero Intrapartum Treatment (EXIT) technique was designed to establish a secure neonatal airway. This procedure allows neonatal tracheal intubation while the uteroplacental circulation maintains fetal oxygenation in a partial fetal delivery during cesarean section. However, it must be emphasized that this technique requires a multidisciplinary team, maternal general anesthesia, high surgery times and potential maternal risks such as placental abruption and increased maternal blood loss due to uterine atony. In addition, the clinical algorithm to obtain a neonatal airway can be quite challenging and neonatal mortality has been reported due to the inability in obtaining an airway at birth. Recently, our Mexican group described a novel minimally invasive fetoscopical technique before cesarean delivery that allows prenatal airway control by means of a fetal endoscopic tracheal intubation (FETI) under maternal peridural anesthesia. This procedure attempted to avoid the need for an EXIT procedure and its potential risks. In this review we described the indications, risks and potential benefits of the EXIT technique and its possible replacement by the fetal endoscopic tracheal intubation technique.
