Background Pierre Robin sequence (PRS) patients have an increased risk of difficult intubation due to anatomical airway abnormalities, and intubation simulation with a three-dimensional (3D) printed airway model before anesthesia may facilitate safe airway management. Case We describe the case of a 6.5-year-old boy with a history of PRS (a triad of micrognathia, glossoptosis, and airway obstruction), tracheostomy, and subglottic fibrosis who required general anesthesia. Preparation for this potentially difficult intubation included estimation of endotracheal tube size using a 3D printed airway model derived from 3D computed tomography of the airway, which enabled successful endotracheal intubation via video laryngoscopy. Conclusions If general anesthesia is necessary in patients with dysmorphic features such as PRS and there is a history of tracheal pathology, the possibility of difficult intubation should always be considered and simulation of endotracheal intubation using a 3D printed model of the airway can be helpful clinically in such situations.

The laryngeal mask airway (LMA) Classic™ and Air-Q® are supralaryngeal devices used for airway management in routine and difficult pediatric airways. We describe a novel two-stage technique of insertion of the LMA Classic™ awake prior to induction of anesthesia, to assure oxygenation and ventilation, and after induction removal and placement of the Air-Q® for intubation using the flexible fiberoptic bronchoscope. The LMA Classic's™ pliable design and relatively small size allow it to be easily placed in awake infants. In contrast, the Air-Q® is an excellent device for intubation because of its larger internal diameter and removable 9 mm adapter. Our goal was to reduce unpredictability and potentially increase the safety of induction of anesthesia and intubation in infants with Pierre Robin sequence. By using these devices in a two-stage approach we created a technique for consistent oxygenation, ventilation, and intubation in these infants.
