Trans Nasal Endoscopy by Dr.
Christopher Chang. Produced by Fauquier Ear Nose and Throat
Consultants in Warrenton Virginia We have a typical patient getting ready
to undergo transnasal endoscopy. The endoscope is threaded through the
nasal cavity to the posterior aspect of the nasopharynx. In the nasopharynx, I’ll have the patient
undergo several speech tasks. The endoscope is then passed beyond this
point in order to visualize the vocal cords.
At this point I’ll have the patient undergo a glide. At this point, I will turn on the stroboscopy in order to see the vocal cord motions. Hopefully this video provides some idea
of what is involved in a transnasal endoscopy.
