How do you deal with a hole in your eardrum from having tubes put in when scuba diving?

You don't. You can't dive this way. However once the tubes are removed (or absorbed ... I'm not a physician) and the holes heal (which they will), you should be able to dive. I say "should" since you probably need to know that the underlying problem for which you needed the tubes is also resolved. Any Scuba class (in the US) will require you to fill out a medical form and you will probably need a doctors release to dive. However, it is only your doctor that can answer this question for you. But the simple answer is when you eardrum is healed with the tubes no longer being present, you should be able to dive sometime in the future. I included a link in the link section to the standard medical form used by the different certification agencies so you can present it to your doctor if you would like.
