What's the benefits?

I have a 4 yr old who has had problems with his left ear getting stopped up and yeast. Now his ears have dark wax and the doctors say that his ears look ok. I check them every once in a while for yeast and blockage. The doctor has told me to put hydrogen peroxide in his ears, but I've done that before and gave him swimmer's ear.

Can ozone ear insufflation help this? If so what is it, and how do I do it? I have an Enaly OZX300U. Will this work?
