What are the different types of implanted hearing devices available for individuals with hearing loss?

There are three main types of implanted hearing devices for individuals with hearing loss: cochlear implants, bone-anchored hearing aids (BAHA), and middle ear implants. Cochlear implants are surgically implanted devices that directly stimulate the auditory nerve. BAHA devices use bone conduction to bypass the outer and middle ear, transmitting sound vibrations directly to the inner ear. Middle ear implants are surgically placed in the middle ear to amplify sound vibrations.
