Hi Sir,
Sorry to hear about your problem. It seems that you have got CSOM with tympanic membrane perforation. If there is perforation, it can be closed only by surgery.
But for hearing improvement, you can try a hearing aid. Before that you need to do a pure tone audiometry to confirm the hearing loss.
