 If there's fluid, scar tissue, anything, other pathologies, you don't have that because it changes the tissue layers of the eardrum, of the tympanic membrane. And so you don't always see that. So we look to see if the eardrum is healthy. The three small bones are right behind the eardrum in the middle ear. So we can't see them, but you can see actually the elbow of one of them and you can see parts of them kind of through there. We look to make sure the eardrum is intact. But then we also take a really good look at the outer ear.
