I have tried all sorts of methods in order to obtain the closest and most vivid images possible. I tried cameras mounted on the surgical headlight which did work... but there was too much motion artifact leading to unusable footage. Even though I thought my head was absolutely still, it really was not.
What I found worked best is using the video tower used for sinus surgery in my hospital with the camera-head attached to the overhead light-handle. Thankfully, my hospital uses HD equipment with 3CCD camera-head, so the video footage is spectacular. And because the camera-head is mounted on a light-handle, the footage obtained is absolutely still.
The footage is recorded digitally directly onto a hard drive which I than transfer to a USB thumb drive.
Along with this setup, I have a roaming individual with a hand-held camcorder to obtain different angled shots to add variety to the final movie.
So that's how I now do it!
The specific video equipment I use is a Conmed Linvatec HD System... however any sinus surgery video equipment should work even if analog.
