Greetings from AZ,This is just one of the text info from the web about; Nasolaryngoscopy
Check out more through your browser.
'Flexible Nasolaryngoscopy is an examination of your nose, voicebox and upper respiratory tract. During the procedure, a small, flexible, fiberoptic scope (about half the width of a pencil) is inserted into one side of the nose, permitting your doctor to see the curves and small spaces of your nose and larynx. Most people find the procedure to be very tolerable. Your doctor will use numbing medicine to make you as comfortable as possible.'
I have had this exam many times, if the Dr. is knowledgeable, it is not difficult.
NIH is very active in helping SD patients. I have been there, They are great!
