Ex utero intrapartum treatment (EXIT) procedure and simultaneous excision of oral teratoma
1Department of Otolaryngology, Head Neck Surgery, Children's University Hospital, Temple St, Dublin.
We report a case of a large oral teratoma in a foetus diagnosed on antenatal ultrasound. Due to the anticipated difficulty in securing the airway at birth an ex-utero intrapartum treatment (EXIT) procedure was planned. In this case simultaneous excision of the tumour mass was carried out while on placental support this allowed safe procurement of the airway and successful delivery of an otherwise healthy infant. This case highlights the challenge presented by such unusual cases and illustrates the successful treatment of this condition.
