Self-Reported Usage, Functional Benefit, and Audiologic Characteristics of Cochlear Implant Patients Who Use a...

Area of Science:

• Audiology
• Otorhinolaryngology
• Biomedical Engineering

Background:

• Bimodal listening, combining cochlear implant (CI) and contralateral hearing aid (HA), is common for unilateral CI users.
• Understanding patient attitudes and perceived benefits of HA use post-CI is crucial for effective management.

Purpose of the Study:

• To investigate the attitudes, usage patterns, and perceived benefits of hearing aid use in patients with unilateral cochlear implants.
• To provide guidance for counseling patients regarding bimodal listening strategies.

Main Methods:

• A questionnaire was administered to 94 patients with unilateral CI and bimodal listening experience.
• Data collected focused on attitudes toward HA use, usage patterns, and perceived bimodal benefits.

Main Results:

• Eighty participants continued HA use, reporting adaptation within 3 months and improved hearing in various conditions.
• Continuing users perceived benefits like better sound quality, music enjoyment, and acoustic balance.
• Discontinuing users found no additional benefit or signal degradation from HA use.

Conclusions:

• A majority of unilateral CI users experience functional and perceived benefits from continued HA use.
• Counseling should encourage unilateral CI recipients to trial HA use to determine individual bimodal benefits.
• Audiograms and speech recognition alone do not predict bimodal benefit, highlighting the importance of subjective patient reports.
