A fiberoptic nasopharyngoscope is a handy tool to check patients for suspected foreign bodies (e.g. fishbone stuck in throat) or laryngeal edema. Depending on the diameter of your fiberoptic cable, it may be fairly uncomfortable for the patient despite generous viscous lidocaine instillation through the nares and nebulized lidocaine. Alternatively or additionally, you can make your own lidocaine-oxymetazoline nasal atomizer which works well.
What if the patient is STILL not tolerating the procedure well?
Trick of the Trade
Use a nasal trumpet guide to help with nasopharyngoscopy
Often the most painful part of the NP scope procedure is the right-angle turn inferiorly that the camera takes just passed the conchae. A soft, more malleable nasal trumpet serves as added padding so that the fiberoptic cable doesn’t contact the sensitive mucosal structures of the nasal passage. Additionally it helps to guide the scope straight to your target area of the posterior pharynx and larynx. Note that you may need to pull the nasal trumpet out slightly if it obscures your view as shown the last image.
