Unfortunately, there is no solution to sensorineural deafness medically. You could opt for Bone Anchored Hearing Aids, which are anchored to the skull bone behind your Right Ear. This will amplify and conduct the sound perceived by the hearing aid microphone onto the only hearing sound cochlea of your Left Ear through your skull bones. BAHA costs about ₹3-4 lakhs and surgery to fix it another ₹60000 to ₹1lakh.
