Maybe not breathe because it looks like there is no hole for air to escape through the ears based on the drawings I have seen. So, it looks like the pipes, the tubes, the canals, goes up to the backside of the ear. It's on the other side of the eardrum. A hole goes from the outside and goes into your head and to your eardrums. The hole from your mouth goes up to your ears. I would wonder if the two holes connect so you can breathe out of your ears. I don't know but probably not. But I would have to research this. But it does seem to connect.
