Totally Implantable Hearing Implant Revision Surgery Indications and Outcomes.

Objective: Analyze indications, findings, and outcomes of revision procedures for a totally implantable active middle ear implant (AMEI) over the past 17 years.

Study Design: Retrospective review.

Setting: Single institution, private practice setting.

New Considerations for a Totally Implantable Active Middle Ear Implant.

Totally implantable active middle ear implants (AMEI) provide full-time hearing amplification to those with moderate to severe sensorineural hearing loss. While technology in conventional hearing aids (CHA) has advanced greatly, limitations remain for people with active lifestyles, limited vision or dexterity, and hearing aid fit issues. Furthermore, direct-drive properties of AMEI are thought to provide those with inefficient middle ear transfer functions a distinct advantage in delivering prescribed sound to the cochlea, ultimately improving speech understanding with less distortion.

Speech Perception Gap Is Predictive of an Active Middle Ear Implant Advantage.

Objective: Evaluate whether the difference between word recognition score (WRS) obtained unaided under earphone and with a hearing aid (HA), the speech perception gap (SPgap), is predictive of performance with a totally implantable active middle ear implant (AMEI).

Study Design: Retrospective review of systematically collected data.

Setting: Private otologic practice.

Comparing Light-Driven Contact Hearing Aids with Acoustic Hearing Aids: Data and Clinical Tips.

Introduction: Contact hearing aids (CHA) offer potential advantages over conventional acoustic hearing aids (AHA) in terms of sound quality, reduced occlusion, and increased high-frequency gain. This study evaluates objective and subjective outcome data for CHA compared to AHA.

Methods: Clinical outcome data were retrospectively reviewed for patients wearing CHA.

Spectrotemporal weighting of binaural cues: Effects of a diotic interferer on discrimination of dynamic interaural differences.

Spatial judgments are often dominated by low-frequency binaural cues and onset cues when binaural cues vary across the spectrum and duration, respectively, of a brief sound. This study combined these dimensions to assess the spectrotemporal weighting of binaural information. Listeners discriminated target interaural time difference (ITD) and interaural level difference (ILD) carried by the onset, offset, or full duration of a 4-kHz Gabor click train with a 2-ms period in the presence or absence of a diotic 500-Hz interferer tone.

Nonuniform temporal weighting of interaural time differences in 500 Hz tones.

The discrimination and lateralization of interaural time differences (ITD) in rapidly modulated high-frequency sounds is dominated by cues present in the initial portion of the sound (i.e., at sound onset).
