Teratomas are true neoplasms composed of tissues from all three germinal layers and may exhibit variable levels of maturity. They have an unknown origin and eccentric microscopic appearance. Airway control is most challenging in such patients. In this case, we describe the anesthetic management of a patient with a large tongue teratoma that was successfully treated with surgery.
| Introduction|| |
Teratomas are defined as true neoplasms composed of multiple tissues, foreign to the site from which they originate. They are the most common extragonadal germ-cell tumors occurring in childhood, consisting of tissues from at least two of the three germ layers. These tumors are most often benign in their histology, but result in a high degree of morbidity and possible mortality by virtue of their size and location, causing airway obstruction and respiratory distress. They arise most commonly in a midline or paraxial location in the sacrococcygeal region. Ninety percent of head and neck teratomas present during the neonatal and infantile period, predominantly involving the neck and nasopharynx, and occur in one in every 20 000–40 000 births . Of the head and neck teratomas, pure oral presentation is especially rare, with most of the cases involving the tongue .
| Case report|| |
A 3.2-kg male baby was born at 38 weeks of gestation with a mass protruding from his mouth ([Figure 1]). The mother did not undergo ultrasonography examinations during her pregnancy, and presented to the emergency room for the first time at term. An emergency cesarean section was carried out because of fetal distress. A male child was born with a large tumor protruding from the oral cavity. The mass was bleeding because of handling, had a smooth and firm surface, and originated from the tongue. The baby had respiratory distress because the mass caused airway obstruction. There were copious secretions in the mouth. Intubation attempts were made but failed. Therefore, oxygen was supplied through a nasal cannula, and the baby obtained some relief. The patient was shifted to the operation theater immediately, and excision of the tumor was scheduled. Any associated congenital malformation was not detected. The tongue was also protruding along with the mass. In the operation theater, equipment necessary to manage a difficult airway were kept ready. The possibility of tracheotomy was also mentioned to the parents. The infant was positioned supine, and monitors were attached; the intravenous line was secured. The patient was oxygenated with 100% oxygen through a nasal cannula. The patient was premedicated with injected atropine 0.01 mg/kg and injected ondansetron 0.1 mg/kg. The patient was administered ketamine 2 mg/kg. One puff of 10% lignocaine was sprayed on the vocal cord area. Next, size 0 Miller's laryngoscope blade was carefully introduced through the left mouth corner with an assistant gently pulling the tumor aside. The blade tip was directed posteromedially, and a part of the glottis could be visualized (Cormack and Lehane grade III) with the aid of gentle external manipulation of the larynx. We then threaded a 2.5-mm internal-diameter uncuffed endotracheal tube into the trachea under visual guidance after a couple of attempts to align the tube tip to the glottic opening. After confirmation of correct placement, the tube was fixed, and a pharyngeal pack was passed around the tube to avoid aspiration of blood. Ventilation was assisted by a pediatric breathing circuit and maintained with sevoflurane 2% and N2O and O2 and ketamine if required. For adequate analgesia, fentanyl 2 μg/kg was administered. Proper suctioning was performed regularly. The mass was totally excised, and there was profuse bleeding when the mass was excised (around 50 ml), which was controlled and replaced with 50 ml of packed red cell transfusion. The patient's heart rate was 160–180 beats/min, and his saturation was 100% throughout the surgery. The operation lasted 40 min, and the mass was 10 × 5 × 5 cm in diameter ([Figure 2]). The patient was extubated when he was fully awake. The extubation process was smooth, and his recovery was uneventful. Postoperatively, the patient was maintained in the lateral position. There were no perioperative problems. The histological diagnosis was consistent with congenital teratoma.
| Discussion|| |
Teratomas occur in one out of 4000 live births . The occurrence of head and neck teratomas is generally localized to the neck and nasopharynx. It is reported that more than 90% of oral teratomas are diagnosed during the perinatal period. Ultrasonography is useful in prenatal diagnosis , particularly for oropharyngeal teratomas that interfere with fetal swallowing of amniotic fluid. Polyhydramnios is the most characteristic finding associated with fetuses with head and neck teratomas. In our case, no antenatal ultrasonography report was available; thus, the mass was detected only after delivery. When oral teratomas grow, they tend to protrude outside of the mouth, rather than posteriorly toward the oropharynx. In addition, children with oral teratomas have been reported to have associated anomalies including cleft palate , cystic hygroma, and other multifocal teratomas. In our case, no associated anomalies were found.
Airway control is most challenging in such patients. Upper airway difficulty causes anticipated functional problems at the hypopharynx . Therefore, anesthesia should be planned accordingly to first secure the airway. Conventionally, fiberoptic nasal intubation would have been a better choice, but because of nonavailability of a pediatric scope preparations to surgically secure the airway were kept ready . Along with difficult airway management, the importance of proper suctioning should also be kept in mind. In cases of anticipated difficult intubation with intraoral tumors, our goals of management should be careful assessment of the airway, provision for alternative emergency surgical airway, exclusion of any congenital lesions, check for laryngoscopy if possible, and establishment of a reliable airway with an appropriate induction agent . In this case, check laryngoscopy could not be performed as the mass occupied a major working place for laryngoscopy.
Early resection is advised, especially for airway-obstructing teratomas. As an oral teratoma is well defined, complete excision is usually possible , as was accomplished in our case. Recurrences are rarely seen in head and neck teratomas.
