CROS Application in CI

Summary

Bilateral profound sensorineural hearing loss (PSNHL) is often treated with Cochlear Implants. The majority of bilaterally deafened patients, however, often only receive a unilateral cochlear implant (CI), with resultant limitations related to monaural listening. For unilateral CI users, the deficits inherently associated with monaural listening remain despite the considerable benefits achieved through implantation. Providing bilateral input to monaural listeners (MLs) overcomes some of these disadvantages. Treatment by contralateral routing of signal (CROS) hearing aids, where the signal of interest is routed from the impaired (deaf) ear to the normal cochlea for processing is a promising alternative in unilateral CI recipients who cannot benefit from bilateral CIs. Utilizing CROS technology provides a less invasive alternative for patients who are unable or unwilling to undergo a second CI surgery and offers an innovative approach to resolving the auditory deficits associated with monaural listening. CROS technology has been used to treat traditional monaural listeners since 1965. When applied to unilateral CI users, this novel approach can overcome a key limitation of current treatment by restoring access to sound from the non-implanted ear and improving speech perception in noise.

Benefits of a Contralateral Routing of Signals (CROS) System in Unilateral CI-recipients

The objective is to investigate the new Naida CROS device in adult recipients including chronic phases and to generate some preliminary pre-launch data. The formal study objectives are to...

Recipients With Limited Bimodal Benefit: HA or CROS

The rationale is to determine (in individuals with limited perceived bimodal benefit) whether the CROS device may be a better solution for obtaining two-sided input. If yes, this study wou...

Real-World Benefit From Directional Hearing Aids

Directional microphone hearing aids have been shown to provide benefit for individuals with hearing loss in a number of laboratory experiments. However, few studies have investigated the r...

Medical and Biotech [MESH] Definitions

The interval between two successive CELL DIVISIONS during which the CHROMOSOMES are not individually distinguishable. It is composed of the G phases (G1 PHASE; G0 PHASE; G2 PHASE) and S PHASE (when DNA replication occurs).

Functionalization of exogenous substances to prepare them for conjugation in PHASE II DETOXIFICATION. Phase I enzymes include CYTOCHROME P450 enzymes and some OXIDOREDUCTASES. Excess induction of phase I over phase II detoxification leads to higher levels of FREE RADICALS that can induce CANCER and other cell damage. Induction or antagonism of phase I detoxication is the basis of a number of DRUG INTERACTIONS.

The period of the CELL CYCLE following DNA synthesis (S PHASE) and preceding M PHASE (cell division phase). The CHROMOSOMES are tetraploid in this point.

The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.

CELL CYCLE regulatory signaling systems that are triggered by DNA DAMAGE or lack of nutrients during G2 PHASE. When triggered they restrain cells transitioning from G2 phase to M PHASE.
