Sir, there are a bunch of tests that has to be done straight away. Have u done BERA test? What all tests have you done? If BERA test shows profound hearing loss, we usually try using hearing aid for 3 months along with speech therapy, still if it dosent work u have to start thinking about Cochlear implant surgery.
Next Steps
I would like to know what all tests u have done till now, would be more than happy to guide you.
