Question

which one of the following is the best way to treat nerve deafness?
surgical implantation of artificial cochlea
usage of hearing aids that intensify incoming sounds
surgical fusion of the bones found in the middle ear
creation of new hair cells using stem cells

Explanation:

Hearing aids amplify sounds but are less effective for nerve deafness as the issue is with the auditory nerve. Surgical fusion of middle - ear bones helps with conductive hearing loss, not nerve deafness. Creating new hair cells with stem cells is still in experimental stages. The surgical implantation of an artificial cochlea is a well - established treatment for severe to profound nerve deafness as it bypasses the damaged auditory hair cells and directly stimulates the auditory nerve.

Answer:

Surgical implantation of artificial cochlea
