Abstract

We present two pediatric patients, one with Pierre Robin syndrome and one with temporomandibular joint ankylosis with limited mouth opening. They had historical and physical evidence of airway obstruction, difficult feeding, and sleep disturbance. They were scheduled for oromaxillofacial surgery. In each case, two different-sized fiberoptic bronchoscopes were used for nasotracheal intubation. After loss of consciousness following an IV injection of ketamine or inhalation of sevoflurane while maintaining spontaneous respiration, 10% lidocaine was sprayed into one nostril. Following insertion of a 60 cm Olympus LF-2 fiberoptic bronchoscope (OD: 3.8 mm) through the same nostril without tube placement, the vocal cords were visualized and topical anesthesia of the larynx was achieved by spraying 2% lidocaine through the biopsy channel. Thirty seconds later, the bronchoscope was passed into the trachea and 2% lidocaine was sprayed intratracheally. Then, the bronchoscope was withdrawn. An endotracheal tube was advanced through the same nostril and positioned in the nasopharynx and the ultrathin fiberoptic bronchoscope (OD: 2.2 mm) was threaded through the tube. There was neither a cough nor laryngeal spasm during advancement of the tube into the trachea. Extubation was performed without compromise in the operating room. The patients were discharged uneventfully.
