Auditory Brainstem Response (ABR) Recording of Simultaneous Electric-Acoustic Stimulation between Round Window Membrane and Basal Part of Cochlear Bone in guinea Pigs. Extracochlear electric-acoustic stimulation (EAS) between the round window membrane and the basal part of the cochlear bone exhibits distinct auditory brainstem response (ABR) characteristics. The use of EAS in individuals

Speech Recognition for Pediatric Electric-Acoustic Stimulation Users with Unilateral Hearing Loss. Pediatric cochlear implant (CI) recipients with unilateral hearing loss (UHL) and functional low-frequency acoustic hearing in the implanted ear could be fit with an electric-acoustic stimulation (EAS) device, which is the combination of acoustic and CI technologies in one device. Outcomes

Speech Recognition and Subjective Hearing Abilities for Electric-Acoustic Stimulation Users With Unilateral Hearing Loss. Some cochlear implant (CI) recipients with unilateral hearing loss (UHL) have functional acoustic hearing in the implanted ear, warranting the fitting of an ipsilateral electric-acoustic stimulation (EAS) device. The present study assessed speech recognition and subjective

Hybrid Cochlear Implant Outcomes and Improving Outcomes With Electric-Acoustic Stimulation. Electric-acoustic stimulation (EAS) provides cochlear implant (CI) recipients with preserved low-frequency acoustic hearing in the implanted ear affording auditory cues not reliably transmitted by the CI including fundamental frequency, temporal fine structure, and interaural time differences (ITDs

An overview of factors affecting bimodal and electric-acoustic stimulation (EAS) speech understanding outcomes. Improvements in device technology, surgical technique, and patient outcomes have resulted in a broadening of cochlear implantation criteria to consider those with increasing levels of useful low-to-mid frequency residual acoustic hearing. Residual acoustic hearing allows in combination to enhance listening outcomes also remains unclear. The understanding of how acoustic and electric speech information is fundamentally combined and utilised by the listener may allow for the optimisation of device fittings and frequency allocations to provide best bimodal and electric-acoustic stimulation (EAS) patient outcomes. This article will provide an overview of contributing factors

Influence of Electric Frequency-to-Place Mismatches on the Early Speech Recognition Outcomes for Electric-Acoustic Stimulation Users. Cochlear implant (CI) recipients with hearing preservation experience significant improvements in speech recognition with electric-acoustic stimulation (EAS) as compared to with a CI alone, although outcomes across EAS users vary. The individual differences

Incidence of Cochlear Implant Electrode Contacts in the Functional Acoustic Hearing Region and the Influence on Speech Recognition with Electric-Acoustic Stimulation. To investigate the incidence of electrode contacts within the functional acoustic hearing region in cochlear implant (CI) recipients and to assess its influence on speech recognition for electric-acoustic stimulation (EAS) users

Electric-Acoustic Stimulation After Reimplantation: Hearing Preservation and Speech Perception. Hearing preservation after cochlear implantation allows for fitting of acoustic and cochlear implant technologies in the same ear, known as Electric-Acoustic Stimulation (EAS). Cochlear implant recipients with EAS who experience an internal device failure face the additional risk of residual hearing

Electric-Acoustic Stimulation Outcomes in Children. This study investigates outcomes in children fit with electric-acoustic stimulation (EAS) and addresses three main questions: (1) Are outcomes with EAS superior to outcomes with conventional electric-only stimulation in children? (2) Do children with residual hearing benefit from EAS and conventional electric-only stimulation when compared

Hearing Preservation Outcomes After Cochlear Implantation Depending on the Angle of Insertion: Indication for Electric or Electric-Acoustic Stimulation. This study reviewed outcomes of hearing preservation (HP) surgery depending on the angle of insertion (AOI) in a cochlear implant (CI) patient population who used electric stimulation (ES) or combined electric-acoustic stimulation (EAS

Multicenter US Clinical Trial With an Electric-Acoustic Stimulation (EAS) System in Adults: Final Outcomes. To demonstrate the safety and effectiveness of the MED-EL Electric-Acoustic Stimulation (EAS) System, for adults with residual low-frequency hearing and severe-to-profound hearing loss in the mid to high frequencies. Prospective, repeated measures. Multicenter, hospital. Seventy-three

Masking release with changing fundamental frequency: Electric acoustic stimulation resembles normal hearing subjects. It has been shown that patients with electric acoustic stimulation (EAS) perform better in noisy environments than patients with a cochlear implant (CI). One reason for this could be the preserved access to acoustic low-frequency cues including the fundamental frequency (F0

Physiological Mechanisms in Combined Electric-Acoustic Stimulation. Electrical stimulation is normally performed on ears that have no hearing function, i.e., lack functional hair cells. The properties of electrically-evoked responses in these cochleae were investigated in several previous studies. Recent clinical developments have introduced cochlear implantation (CI) in residually-hearing ears

Long-term Hearing Preservation Outcomes After Cochlear Implantation for Electric-Acoustic Stimulation. This study reviewed outcomes of hearing preservation (HP) surgery in a cochlear implant patient population, with clinical follow-up results up to 11 years after implantation. Retrospective case review. Tertiary referral university hospital. Ninety six patients (103 ears) with partial deafness

The Patients Associated With TMPRSS3 Mutations Are Good Candidates for Electric Acoustic Stimulation. To clarify the frequency of TMPRSS3 mutations in the hearing loss population, genetic analysis was performed, and detailed clinical characteristics were collected. Optical intervention for patients with TMPRSS3 mutations was also discussed. Massively parallel DNA sequencing (MPS) was applied for the target exon-sequencing of 63 deafness genes in a population of 1120 Japanese hearing loss patients. Hearing loss in 5 patients was found to be caused by compound heterozygous TMPRSS3 mutations, and their detailed clinical features were collected and analyzed. Typically, all of the patients showed ski slope type audiograms and progressive hearing loss. Three of the 5 patients received electric acoustic

Speech Perception With Combined Electric-Acoustic Stimulation: A Simulation and Model Comparison. The aim of this study is to simulate speech perception with combined electric-acoustic stimulation (EAS), verify the advantage of combined stimulation in normal-hearing (NH) subjects, and then compare it with cochlear implant (CI) and EAS user results from the authors' previous study. Furthermore

[Speech perception with electric-acoustic stimulation : Comparison with bilateral cochlear implant users in different noise conditions]. Cochlear implantation with the aim of hearing preservation for combined electric-acoustic stimulation (EAS) is the therapy of choice for patients with residual low-frequency hearing.

Long-term Follow-up of Hearing Preservation in Electric-Acoustic Stimulation Patients. Hearing preservation (HP) surgery was initiated more than 10 years ago for combined electric and acoustic stimulation (EAS).

To evaluate bilateral EAS efficacy of sound localization detection and speech perception in noise in two cases of high-frequency

and 17% of children with UHL may progress to a bilateral hearing loss (Uwiera et al. 2009; Haffey et al. 2013; Fitzpatrick et al. 2017). Unaided hearing of the implanted ear should be monitored as well (Dillon et al. 2020) and electric-acoustic stimulation should be considered for children with postoperative residual hearing (Skarzynski & Lorens 2010; Wolfe et al. 2017; Park et al. 2019a).As with all
