G.B.
My next to the youngest grandson was found to be deaf. He didn't even respond to the bass drum being banged behind his head. The ENT put tubes in to see if it would help him hear better. When he went in the ear canal he found debris from ear infections that antibiotics had not touched. He cleaned out so much goo.....it took nearly an hour extra.
Once he came out of surgery he could hear and has been able to hear just fine since. The tubes do work themselves out. It is just part of the growing process.
I say get them done and see if it helps.
