Our objective was to evaluate the comparative benefit of CROS systems and contralateral hearing aids (bimodal use) in single sided implantees, and contrast this with bilateral (second-side) cochlear implantation. A prospective, randomized cross-over trial was used to evaluate the two systems. Subjects then continued using their preferred system for an acclimatization period. Performance on speech in noise tasks and localization tasks was evaluated. Subjective benefit was assessed by standardized questionnaires. Speech in noise and localization performance for the systems will be presented, and contrasted with bilateral cochlear implant performance. Implications for the feasibility of using CROS systems or hearing aids as alternatives to bilateral implantation will be discussed.
