Comparing Standard and Anatomy-Based Frequency Fitting in New Cochlear Implant Users Using MAESTRO 9 Software to Assess Hearing Performance Over Time

What this Trial Is About

Researchers are evaluating cochlear implant CI performance over time in three groups of newly implanted CI users. The study compares the standard frequency-band distribution fitting and an anatomy-based fitting method using the MAESTRO 9 software. This research aims to understand how anatomy-based fitting impacts hearing outcomes and quality of life in users, with the study sponsored by Fundacion para la Investigacion Biomedica del Hospital Universitario la Paz. Participants are divided into three groups one fitted with the standard frequency-band distribution, another using anatomy-based frequency distribution aligned with individual electrode tonotopy, and a third group who will use both fittings alternately each week. The third group carries both study maps on their audio processor and switches weekly between the standard and anatomy-based fittings to compare their auditory performance. Throughout the study, participants undergo speech tests in noise and quiet at six months to measure hearing outcomes. Researchers also evaluate sound quality and quality of life in challenging situations. Participants will be monitored regularly, and assessments include speech recognition and subjective evaluations, with the total study duration depending on individual progress and protocol timing.
