An innovative use of malfunctioning flexible fiberoptic bronchoscope for securing airway in a case of large parapharyngeal mass

This case report involves successful nasotracheal intubation using malfunctioning fiberoptic bronchoscope (FOB) in combination with direct laryngoscopy in a patient with difficult airway, classified as Cormack-Lehane grade IV as a result of large parapharyngeal mass. Tip of the insertion cord of our FOB could not be ante- or retro-flexed due to damage to its bending apparatus but its visualization on the display screen was alright. As videolaryngoscope was not available, we used this malfunctioning FOB in conjunction with laryngoscope to create our own indigenous videolaryngoscope and intubated the patient successfully.
