A Case of General Anesthesia for a Young Infant in Whom Intubation Was Suspected to Be Difficult Because of a Thyrolingual Cyst.

This is a case report of an infant who underwent thyrolingual cystectomy under general anesthesia. Two tracheal tubes were used: 1 for nasopharyngeal airway and the other for fiberoptic intubation. With this method, nasal intubation was successfully performed without hypoxia and hypercapnia even in a 3-month-old infant. We concluded this is a useful intubation method for infants who are predicted to be a difficult intubation.
