Maybe less head shaking will help it become less infected?
I'm educating the teacher!
I actually don't think its infected (though obviously can't be sure)
I'll see if I can explain why I think it came back... Aural = ear, hematoma = collection of blood in a localized area in the tissues. With aural hematomas in dogs, a blood vessel breaks inside the tissues of the ear and kind of "leaks" out. So, when we drained it, there was an area already sort of all stretched out in there, and since we had no way of stopping the leak in the blood vessel and there was a bit of head shaking to "help" the leak, it has filled back up.
Of course, it could be infection, which would most definitely need to be drained and attended to, and the only way (well, if there was a lot of redness, swelling and heat coming from the area of the hematoma would give a strong likelyhood of infection, but that would also have be confirmed with a needle) to know for sure is to aspirate ("poke") with a needle again and see what the fluid that is drawn out looks like; bloody & watery = from the leaky blood vessel, thicker opaque fluid with a lighter tone to it and perhaps a green or yellow tinge would indicate infection, and this could be confirmed by taking some and looking at it under a microscope.
Any techs or vets are welcome to correct if I have something not quite right.
