Three surgeries and chemotherapy for recurrence of the tumor have been performed since a male infant with a nasopharyngeal mass was born at a gestational age of 35 weeks. Extended maxillotomy combining Le Fort I osteotomy with midline palatal split was performed at 2 years and 6 months of age. Residual tumor left in the intracranial region had not increased as of 4 years of age. Careful follow-up is needed until the patient reaches adulthood. © 2020 by Mutaz B. Habal, MD.
