Failed or difficult tracheal intubation remains an important cause of mortality and morbidity during anesthesia, especially in infants with anatomical or pathological abnormalities of the airway.We report on a 4.1 kg, 85-day-male infant with a thyroglossal duct cyst at the tongue base who could not be conventionally ventilated and intubated in the supine position.The infant was intubated with a 3-mm endotracheal tube through the laryngeal mask airway (LMA) with guidance of a fiberoptic bronchoscope (FOB).However, the pilot balloon did not pass through the 1.5-mm LMA conduit.After cutting the pilot balloon, we removed the LMA and inserted a central venous catheter guide-wire through the endotracheal tube to increase the endotracheal tube to 3.5 mm.This maneuver allowed us to secure the airway without further problems.
Key Words: fiberoptic bronchoscope; infant; intubation; laryngeal mask airway; thyroglossal duct cyst
