[Hearing preservation: Better hearing with advanced technology]

Preservation of residual hearing after cochlear implantation allows patients the synergetic use of electric and acoustic stimulation (EAS). The application of specific surgical and therapeutic techniques enables the reduction of inner ear trauma, which leads otherwise to complete hearing loss. Due to simultaneous electric and acoustic stimulation, speech understanding is improved especially in noise. EAS is a well-accepted therapeutic treatment for subjects with profound hearing loss in the higher frequencies and no or mild hearing loss in the low frequencies. Several Manufacturers offer individual soft electrodes specially designed for hearing preservation as well as combined electric-acoustic audio processors.
