Abstract: Introduction: Patients with a cochlear implant in one ear and a hearing aid in the other (bimodal) are often not optimally programmed. There is typically little to no coordination between the two devices and the amplification needs of a bimodal listener are different from a patient who only has access to sound through hearing aids. Recently, a bimodal fitting system has been created (Naida Link) that aims to optimize the gains for this population by providing more gain for low frequencies and reduced gain at frequencies corresponding to potential dead regions in the cochlea. It also aligns the loudness growth and dynamic AGC characteristics of the bimodal hearing aid to that of the cochlear implant processor. Methods: The goal of the current study was to determine if bimodal fitting via the Naida Link yielded better speech understanding abilities compared to an individual’s current standard clinical fitting of a cochlear implant and hearing aid. To test this, patients were tested with unlinked and uncoordinated cochlear implant and hearing aid programs (only relative loudness for the two ears was adjusted). Patients were also tested with the Naida Link system. Speech understanding in noise was compared in the two configurations. Results: Preliminary results will be discussed. Conclusion: An efficient and effective bimodal fiiting methodology is beneficial to patients as well as clinicians. CI2019 Pediatric Poster Abstracts Poster Number: 2 Abstract ID: 83 Title: Bilingual Language Proficiency in Adolescents with Typical Hearing and Adolescents with Hearing Loss Category: Rehabilitation/Educational Aspects Authors: Alliete Alfano, PhD 1, Stacey Lim, AuD, PhD 2, Carolina Gutierrez-Rivas, PhD 2; 1Communication Sciences and Disorders, Florida Intl. Univ., Miami, FL, 2Central Michigan Univ., Mount Pleasant, MI. Abstract: Introduction: Though there is evidence demonstrating children with disabilities are able to become bilingual, there are still concerns of how children with hearing loss can learn more than one spoken language (Thomas, El-Kashlan, & Zwolan, 2008). In more recent years, it has been found that there are advantages to speaking more than one language at home, particularly if the parents are fluent in other spoken languages (Thomas, El-Kashlan, & Zwolan, 2008). In the past, however, parents of children with hearing loss were strongly encouraged to speak one language only; generally, this was the language of the majority population in the country--so for example, bilingual parents in the United States were encouraged to speak only English with their children with hearing loss, regardless of the parents’ proficiency in English. The purpose of this study was to compare English and Spanish proficiency in bilingual adolescents with and without hearing loss. Methods: Sixteen bilingual (English/Spanish) adolescents, 12-19 years old, participated in the study. Eight of the adolescents had severe to profound bilateral sensorineural hearing loss. Hearing loss was identified by 2 years of age and hearing aid fitting/cochlear implantation occurred by 2 1/2 year of age. The remaining 8 adolescents had typical hearing and were age-matched to the adolescents with hearing loss. Participants completed a bilingual history questionnaire and the Woodcock-Muñoz Language Survey in English and Spanish. Results: An independent-samples t-test was run to determine if there were differences in language proficiency scores in English and Spanish between bilingual adolescents with typical hearing and bilingual adolescents with hearing loss. English Listening proficiency was higher for adolescents with typical hearing (101.2± 9.6) than for adolescents with hearing loss (76.1 ± 18.1), a statistically significant difference of 4.9, t(19) = 6.331, p = .000. English Oral Language proficiency was higher for adolescents with typical hearing (101.8± 7.7) than for adolescents with hearing loss (71.0 ± 14.7), a statistically significant difference of 6.0, t(19) = 4.293, p = .000. Spanish Listening proficiency was higher for adolescents with typical hearing (79.0± 16.5) than for adolescents with hearing loss (25.4 ± 22.1) a statistically significant difference of 8.4, t(19) = 6.356, p = .000. Spanish Oral Language proficiency was higher for adolescents with typical hearing (67.9± 17.9) than for adolescents with hearing loss (33.5 ± 23.5) a statistically significant difference of 9.1, t(19) = 3.081, p = .001. Conclusion: Results indicate that bilingual adolescents with typical hearing have higher language proficiency in both English and Spanish when compared to bilingual adolescents with hearing loss. Additionally, English proficiency was higher for both groups. CI2019 Pediatric Poster Abstracts Poster Number: 3 Abstract ID: 224 Title: Quality of Life Outcomes After Cochlear Implantation in Older Adults: A Systematic Review Category: Audiology Authors: Ellen Andries, Drs, MSc AUD, Griet Mertens, PhD, MSc AUD, Paul Van de Heyning, MD, PhD;Department of Otorhinolaryngology, Univ. Hosp. Antwerp, Antwerp, Belgium. Abstract: Introduction: According to the WHO, one third of adults aged 65 or older has disabling hearing loss. Those with severe to profound sensorineural hearing loss could benefit from cochlear implants (CI) as it is shown in several studies that CI can significantly improve auditory gains, cognition and quality of life (QOL). There is growing interest in older CI recipients and their QOL, as QOL is an issue especially of reimbursement strategies. To assess QOL in CI recipients, clinical psycho-acoustic measures such as speech recognition and pure tone audiometry alone are not all-embracing. QOL also needs to be evaluated in a more general way, taking into account personal factors and functional benefits that cannot be described by (speech) audiometry. Therefore, numerous QOL measurement instruments have been developed, divided in two categories: disease-specific and generic instruments. Generic instruments can be used in various diseases as they assess general health states, while disease-specific measures assess particular diseases. Nevertheless, there is lack of consensus regarding QOL measures in CI recipients. Moreover, there are less data in QOL changes available in recent articles compared to data in psycho-acoustic measures changes in CI. Therefore, the aim of this study is to critically review current literature concerning QOL in CI recipients. Methods: Studies were selected by searching MEDLINE (PubMed) and Cochrane Library and by checking reference lists of relevant articles. No restrictions were imposed regarding language, publication date or publication status. Inclusion criteria were as follows: (1) The study sample were adults aged 50 and older with bilateral severe to profound hearing loss with postlingual onset (2) All subjects received a multi- electrode CI (3) QOL was assessed before and after implantation. The following search string was used: (‘Cochlear Implants’[Mesh] OR ‘Cochlear Implantation’[Mesh] OR (cochlear implant*)) AND (‘Quality Of Life’[Mesh] OR quality[Text Word] OR life[Text Word] OR benefit[Text Word] OR self-report[Text Word] OR self-reported[Text Word] OR selfreported[Text Word] OR patient-report[Text Word] OR patient- reported[Text Word]) AND (adult[Text Word] OR adults[Text Word]) AND (‘Aging’[Mesh] OR ‘Aged’[Mesh] OR ‘Geriatrics’[Mesh] OR elder[Text Word] OR elderly[Text Word] OR elders[Text Word] OR old[Text Word] OR older[Text Word] OR aged [Text Word] OR aging[Text Word] OR ageing[Text Word] OR senior[Text Word] OR seniors[Text Word] OR geriatric[Text Word] OR geriatrics[Text Word]) Results: Title and abstract of 475 articles were screened and 35 articles were selected for full-text assessment. The general results will be presented at CI 2019. Conclusion: Current literature shows that QOL improves post CI. However, no instruments or methods are generally accepted to assess QOL in CI recipients. The overall results will be presented at CI 2019. CI2019 Pediatric Poster Abstracts Poster Number: 4 Abstract ID: 300 Title: Comparing Measures of the Cochlear Implant Electrode-Neuron Interface to Clinical Measures in Listeners with Enlarged Vestibular Aqueduct Category: Audiology Authors: Julie G. Arenberg, PhD, Kelly Jahn, AuD, Molly Bergen, BS;Speech and Hearing Sciences, Univ. of Washington, Seattle, WA. Abstract: Introduction: Etiology of hearing loss can lead to varying development and formation of the inner ear, resulting in differing qualities of the interface between individual, cochlear implant (CI) electrodes and the auditory nerve. However, the relation between etiology and psychophysical and impedance measures is not well understood. The goal of the present study was to compare detailed psychophysical and impedance measures obtained in a small sample of subjects with enlarged vestibular aqueduct (EVA) to those obtained clinically in a much larger sample of patients. Methods: Detailed psychophysical measures were obtained in 16 CI listeners that received their first implant during childhood. Four participants were diagnosed with enlarged vestibular aqueduct (EVA), which is characterized

  • Effects of Retinoid Treatment on Cochlear Development, Connexin Expression and Hearing Thresholds in Mice
    Journal of Otorhinolaryngology, Hearing and Balance Medicine Article Effects of Retinoid Treatment on Cochlear Development, Connexin Expression and Hearing Thresholds in Mice Yeunjung Kim ID and Xi Lin * Department of Otolaryngology, Emory University School of Medicine, 615 Michael Street, Room# 543, Atlanta, GA 30322-3030, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-404-727-3723; Fax: +1-404-727-6256 Received: 5 July 2017; Accepted: 17 October 2017; Published: 23 October 2017 Abstract: Mutations in GJB2, gene coding for connexin 26 (Cx26), and GJB6, gene coding for connexin 30 (Cx30), are the most common genetic defects causing non-syndromic hereditary hearing loss. We previously reported that overexpression of Cx26 completely rescues the hearing in a mouse model of human GJB6 null mutations. The results suggest that therapeutic agents up-regulating the expression of Cx26 may potentially be a novel treatment for non-syndromic hereditary deafness caused by Cx30 null mutations. Retinoids are a family of vitamin A derivatives that exert broad and profound effects on cochlear protein expression including connexins. They are readily available and already utilized as therapeutic agents for recurrent otitis media and hearing loss due to noise exposure. In this study, we characterized the expression of Cx26 and Cx30 in the postnatal inner ear by different retinoids including retinyl palmitate (RP), the main source of vitamin A in over-the-counter (OTC) supplements, retinyl acetate (RAc) which is an isomer of RP, and all-trans-retinoic acid (ATRA), the most active retinoid derivative. The results revealed ATRA significantly increased cochlear Cx26 expression and improved hearing in Cx30 knockout (KO) mice by 10 dB suggesting its potential benefits as a therapeutic agent.
