Bimodal hearing in asymmetrical hearing loss: prospective study in patients with same CI and HA devices
With progressive expansion in candidacy criteria for CI, it is increasingly common to implant candidates with severe to profound hearing loss in one side and substantial acoustic hearing in the contralateral hear (Mild-moderate HL up to 500Hz and severe to profound > 1000 Hz). These patient typically display > 50% sentences recognition in quiet and poor recognition in noise. One critical factor is the long duration of hearing loss with variable deprivation of the implanted side.
