On Oct 23, 2009, Dr. Oz (his show) with the assistance of Dr. Jonathan Aviv, demonstrated a procedure called Nasal Endoscopy which is the main method of evaluating a patient with hoarseness. A pretty good and accurate demonstration I may add.
Watch the video clip here.
Of course, I have produced a few video clips of the same of which one can be viewed below. Click here to watch one being performed on a child. Read more about this procedure here as well as what happens when the voice doesn't sound normal here.
