[Congenital teratoma of the skull base: case report of an interdisciplinary treatment].

Teratomas of the oropharynx are quite rare congenital tumors. Even more rare than oropharyngeal teratomas are those with additional intracranial extension. Reviewing the literature the prognosis of these cases has been poor. In the majority stillbirth or immediate postpartum death following respiratory obstruction is reported. We present a case of a congenital teratoma of the oral cavity with intracranial extension in a female neonate. After several intraoral tumor resections to establish secure airway in the postpartum period the total tumor resection had to be performed at the age of 6 month via a lateral transmandibular approach to the skull base. By using extraoral distaction devices the operation related microsomia of the mandible could be corrected at the age of 5 years. At 7 years follow-up the girl presented free of recurrence and without any neurological or functional deficits.
