[Teratoma of the rhinopharynx and the infratemporal fossa in neonates: report of 3 cases].
Teratomas are tumors which develop in childhood or early adulthood, generally in the gonads. More rarely these tumors may be found in an axial localization, notably in cervicofacial forms. We report three cases of teratomas observed in rhinopharynx of three neonates operated at the Clocheville General Hospital. We present the main anatomoclinical features of these tumors, focusing on the cervicofacial forms in neonates. All three cases occurred in female neonates presenting acute dyspnea within the first hours of life, requiring intubation in two cases. The first two tumors invaded the infratemoral region and the third was a pediculated tumor of the velum exteriorized via the mouth. In one case antenatal ultrasound had suggested the diagnosis of a right temporomaxillary tumor. Rapid excision of the rhinopharngyeal component allow extubation for the two intubated infants and pathology diagnosis. In the first infant operated at 2 months, the lateral route was adapted to age, with mandibulotomy with section of the coronoid process but preserving the mandibular condyle. The second infant was operated at the age of 3 weeks using a wide frontotemporoperitonial approach then at the age of 3.5 months for recurrence extending to the floor of the temporal fossa and the middle ear. A type C infratemporal approach was used with lost-bone temporal craniectomy. Per-buccal excision was possible in the third infant with resection at the base of implantation. No recurrence has been observed in the first two cases at 3.5 and 2.5 months follow-up in the first two cases. The third infant was lost to follow-up.
