Chronic ear infection in 79 year old

I'm hoping someone can help. My dad is 79 and has developed a chronic ear infection that the doctor recently said may never go away. Until he started wearing hearing aids a few years ago he had never had an ear infection. In the beginning the hearing aid worked well, after a while though wax would build up then infection set in. We've been told that the infection caused both ear drums to perforate and that his hearing loss is a result of this. He has almost no hearing in one ear and severe hearing loss in the other. When he is able to wear his hearing aid in the good ear, he can hear enough to get by but this is becoming difficult since there is usually infection in that ear. He's constantly on antibiotics which don't seem to be doing the trick. I have been thinking maybe it's time to try something else like homeopathy- he does not want surgery. The hearing loss is very difficult for him and those trying to communicate with him. He gets discharge from his ears but not puss, mostly just fluid the continually seems to build up which he tries to control by using tissue or cotton to wipe it up. Any suggestions would be greatly appreciated, I miss our long conversations! I know nothing can restore his hearing but if we could get rid of the infection he could at least wear his hearing aide.

Thanks so much!
