Hey, I hope you get some answers here, cuz I’ve just used a small flashlight and magnification mirror to “peer” into my ear canals. I can’t see much beyond the first quarter inch or so, I’m guessing?
BE careful of trying to remove wax from your ear canals, cuz some can be protective. You can risk poking yourself real good or even giving yourself a case of otitis. I had an overly-enthusiastic audiologist ages ago who used an ear camera to show ear wax on a video screen. He’d whip a stick out of his pencil can, scrape that out of my ears, wipe the stick off on his lab coat and put it back in the pencil can.
Goes without saying, I got BAD otitis real soon afterwards.
