Successful in utero treatment of an oral teratoma via operative fetoscopy: case report and review of the literature.

The prenatal diagnosis of a nasopharyngeal teratoma carries a very grave prognosis. Although these tumors constitute only 9% of all teratomas, all previous cases diagnosed antenatally have been associated with either fetal demise or emergent surgery at birth. Of the fetuses that survive to birth, delivery can be associated with airway obstruction and multiple postnatal surgeries. These complications could be averted if the tumor could be safely treated in utero. We hereby report the successful treatment of an oral teratoma via operative fetoscopy, with the birth of a healthy infant at term.
