Objectives: To 1) describe changes in the electrical stapedial reflex threshold (eSRT), within and across patients over time and 2) to identify the clinical relationship between eSRT and an individual's upper limit of loudness.
Study Design: Retrospective chart review and analysis using a multilevel modeling approach to describe changes in eSRT over time.
Setting: Secondary care center.
Patients: Two-hundred five cochlear implant recipients treated at the cochlear implant center during a 3-year time period.
Intervention(s): Cochlear implantation, eSRT testing, and, electrical upper limits of loudness.
Main Outcome Measure(s): The eSRT over multiple appointments and the cochlear implant recipients' final upper limits of loudness.
Results: Analysis of the eSRT testing indicated stability over time; no global trend was seen in trajectory across the population, b = -0.010, p = 0.899. The relationship between eSRT and user upper limits of loudness revealed a mean decrease of 19.47, units for manufacturer 1, 30.53 units for manufacturer 2, and 0.7 units for manufacturer 3.
Conclusion: Electrical stapedial reflex thresholds remain consistent for individual subjects over time with implant experience being the only variable correlated with eSRT stability (increase in 5% of one standard deviation with each year of experience). In addition, a clinical relationship between eSRT and behaviorally set upper limits of loudness was identified for all three cochlear implant manufacturers available in the United States.

Reversing Cochlear Nucleus Maladaptive Plasticity via Customized Extracochlear Stimulation: A New Approach for Tinnitus Treatment.

Tinnitus, a widespread condition affecting numerous individuals worldwide, remains a significant challenge due to limited effective therapeutic interventions. Intriguingly, patients using cochlear implants (CIs) have reported significant relief from tinnitus symptoms, although the underlying mechanisms remain unclear and intracochlear implantation risks cochlear damage and hearing loss. This study demonstrates that targeted intracochlear electrical stimulation (ES) in guinea pigs with noise-induced hearing loss reversed tinnitus-related maladaptive plasticity in the cochlear nucleus (CN), characterized by reduced auditory innervation, increased somatosensory innervation, and diminished inhibitory neural networks.
View Article and Find Full Text PDFIntroduction: This study aims to investigate the impact of auditory input on postural control in young adult cochlear implant users with profound sensorineural hearing loss. The research explores the relationship between auditory cues and static postural stability in individuals with hearing impairment.
Methods: 34 young adult cochlear implant users, consisting of 15 males and 19 females aged 18-35 years, underwent various balance tests, including the modified Clinical Tests of Sensory Interaction on Balance (mCTSIB) and the Unilateral Stance Test (UST), under different auditory conditions: (1) White noise stimulus present with the sound processor activated, (2) Ambient noise present with the sound processor activated, and (3) Sound processor deactivated.
Exploring the Hearing Improvement and Parental Stress in Children with Hearing Loss Using Hearing Aids or Cochlear Implants.

This study aims to describe the stress levels experienced by parents of children with hearing loss who use conventional hearing aids or cochlear implants, and to assess the correlation between parental stress and the auditory skills acquired by the children. The study was conducted at the Policlinic "Gaetano Martino" in Messina, evaluating data from 42 pairs of parents of children using hearing aids or cochlear implants. Parents completed the LittlEARS Auditory Questionnaire (LEAQ) and the Parental Stress Scale (PSS) 18 months after the initial device (hearing aid or cochlear implant) had been activated.

Background: The aim of this study was to relate response patterns of electrocochleography (ECochG) recordings during cochlear implantation to pre- and postoperative hearing.
Methods: Thirty subjects with either flat (FA, n = 9) or sloping (SA, n = 21) audiograms before cochlear implantation were prospectively included. Real-time ECochG recordings were conducted via the cochlear implant.
