I am assuming you are referring to draining the outer ear. When Justin got his cauliflower ear, we had it drained several times and then our regular docs recommended that we go to an ear specialist to "fix". The Ear Doc sewed 2 cotton rolls to each side of his ear to apply pressure both ways. The pressure would not allow more fluid to enter the outer ear and so no more drainage, swelling, etc.

If you can get enough pressure on both sides of outer ear after draining, my understanding is that will stop the fluid. Getting that type of pressure is what we found to be difficult. Before he went to the specialist, I sent him to school one day with his ear bandaged up and his wrestling headgear holding it all on tight. It didn't work, but the nurses were impressed with how I did it as they had no real solution. The dr's trip before they had wrapped his whole head up.

Through all of the above, the only medicine that was offered was pain med for when they sewed the cotton on. The Dr's didn't have anything to stop the fluid other than applying pressure. Probably not the answer you wanted. Maybe there are veteran guys out there that may have more secrets as to how to deal with cauliflower ear.
