(a) Lateral picture of a patient with simulated cervical spine immobilization using the Philadelphia neck collar. (b) Lateral radiograph of a patient undergoing nasotracheal intubation with the McCoy laryngoscope. The McCoy laryngoscope significantly elevates the epiglottis; therefore, Magill forceps are frequently needed to navigate the nasotracheal tube into the glottic inlet. McCoy: McCoy laryngoscope, MF: Magill forceps, E: Epiglottis, NTT: nasotracheal tube, arrow without marking = glottic inlet. (c) Lateral radiograph of a patient undergoing nasotracheal intubation with C-MAC videolaryngoscope. C-MAC videolaryngoscope maintains the configuration of the airway in its original position, which allows for alignment of the nasal tube tip with the glottic inlet and smooth advancement of the NTT. C-MAC: C-MAC videolaryngoscope. The picture and radiographs were taken after obtaining informed consent
