Pentax High Definition video endoscope VNL-1590STi

I am having the opportunity to compare images using the Pentax standard definition endoscope VNL-1170K and the high-definition VNL-1590STi. This patient has amyloid depositions in the vocal cords. They cause a stiffening of the vocal cord and allow air to leak out.
