Cochlear Implant Surgery

Over the last decade, cochlear implantation has become an increasingly viable alternative for the treatment of profound sensorineural hearing loss in children. Although speech and hearing professionals play an important role in the communicative, social, and academic development of children with cochlear implants, many may be unfamiliar with recent advances in implant technology. This article provides an overview of the components of cochlear implant systems and the speech processing strategies that are currently being used by toddlers, preschoolers, and school-age children. A brief description of cochlear implant surgery and the procedures for programming these devices are also included. Finally, information regarding the use of assistive listening technology in the classroom is presented.

Vestibular Reflex

Vestibular function in cochlear implant candidates varies from normal to total absence of function. In patients with intact vestibular function preoperatively, invasion of the otic capsule places residual vestibular function at risk. Speech-processing strategies that result in large amplitude electrical transients or strategies that employ high amplitude broad frequency carrier signals have the potential for disrupting vestibular function. Five patients were tested with and without electrical stimulation via cochlear electrodes. Two patients experienced subjective vestibular effects that were quickly resolved. No long-term vestibular effects were noted for the two types of second generation cochlear implants evaluated. Histopathological findings from another patient, who had electrically generated vestibular reflex responses to intramodiolar electrodes, indicated that responses elicited were a function of several variables including electrode location, stimulus intensity, stimulus amplitude, and stimulus frequency. Differential auditory, vestibulocolic, and vestibulospinal reflexes were demonstrated from the same electrode as a function of stimulus amplitude, frequency, and duration.

Improve Service Delivery

Educational audiologists often must delegate certain tasks to other educational personnel who function as support personnel and need training in order to perform assigned tasks. Support personnel are people who, after appropriate training, perform tasks that are prescribed, directed, and supervised by a professional such as a certified and licensed audiologist. The training of support personnel to perform tasks that are typically performed by those in other disciplines is calledmultiskilling. This article discusses multiskilling and the use of support personnel in educational audiology in reference to the following principles: guidelines, models of multiskilling, components of successful multiskilling, and "dos and don’ts" for multiskilling. These principles are illustrated through the use of multiskilling in the establishment of a hearing aid monitoring program. Successful multiskilling and the use of support personnel by educational audiologists can improve service delivery to school-age children with hearing loss.

Abstract Background YouTube is increasingly used as a source of healthcare information. This study evaluated the quality of videos on YouTube about cochlear implants. Methods YouTube was searched using the phrase ‘cochlear implant’. The first 60 results were screened by two independent reviewers. A modified Discern tool was used to evaluate the quality of each video. Results Forty-seven videos were analysed. The mean overall Discern score was 2.0 out of 5.0. Videos scored higher for describing positive elements such as the benefits of a cochlear implant (mean score of 3.4) and scored lower for negative elements such as the risks of cochlear implant surgery (mean score of 1.3). Conclusion The quality of information regarding cochlear implant surgery on YouTube is highly variable. These results demonstrated a bias towards the positive attributes of cochlear implants, with little mention of the risks or uncertainty involved. Although videos may be useful as supplementary information, critical elements required to make an informed decision are lacking. This is of particular importance when patients are considering surgery.

Children With Hearing Loss

Background: Consistency of hearing aid and remote microphone system use declines as school-age children with hearing loss age. One indicator of hearing aid use time is data logging, another is parent report. Recent data suggest that parents overestimate their children’s hearing aid use time relative to data logging. The potential reasons for this disparity remain unclear. Because school-age children spend the majority of their day away from their parents and with their teachers, reports from teachers might serve as a valuable and additional tool for estimating hearing aid use time and management. Purpose: This study expands previous research on factors influencing hearing aid use time in school-age children using data logging records. Discrepancies between data logging records and parent reports were explored using custom surveys designed for parents and teachers. Responses from parents and teachers were used to examine hearing aid use, remote microphone system use, and hearing aid management in school-age children. Study Sample: Thirteen children with mild-to-moderate hearing loss between the ages of 7 and 10 yr and their parents participated in this study. Teachers of ten of these children also participated. Data Collection and Analysis: Parents and teachers of children completed written surveys about each child’s hearing aid use, remote microphone system use, and hearing aid management skills. Data logs were read from hearing aids using manufacturer’s software. Multiple linear regression analysis and an intraclass correlation coefficient were used to examine factors influencing hearing aid use time and parent agreement with data logs. Parent report of hearing aid use time was compared across various activities and school and nonschool days. Survey responses from parents and teachers were compared to explore areas requiring potential improvement in audiological counseling. Results: Average daily hearing aid use time was ˜6 hr per day as recorded with data logging technology. Children exhibiting greater degrees of hearing loss and those with poorer vocabulary were more likely to use hearing aids consistently than children with less hearing loss and better vocabulary. Parents overestimated hearing aid use by ˜1 hr per day relative to data logging records. Parent-reported use of hearing aids varied across activities but not across school and nonschool days. Overall, parents and teachers showed excellent agreement on hearing aid and remote microphone system use during school instruction but poor agreement when asked about the child’s ability to manage their hearing devices independently. Conclusions: Parental reports of hearing aid use in young school-age children are largely consistent with data logging records and with teacher reports of hearing aid use in the classroom. Audiologists might find teacher reports helpful in learning more about children’s hearing aid management and remote microphone system use during their time at school. This supplementary information can serve as an additional counseling tool to facilitate discussion about remote microphone system use and hearing aid management in school-age children with hearing loss.

Linguistic Content

Forty-four school-age children who had used a multichannel cochlear implant (CI) for at least 4 years were tested to assess their ability to discriminate differences between recorded pairs of female voices uttering sentences. Children were asked to respond “same voice” or “different voice” on each trial. Two conditions were examined. In one condition, the linguistic content of the sentence was always held constant and only the talker's voice varied from trial to trial. In another condition, the linguistic content of the utterance also varied so that to correctly respond “same voice,” the child needed to recognize that Two different sentences were spoken by the same talker. Data from normal-hearing children were used to establish that these tasks were well within the capabilities of children without hearing impairment. For the children with CIs, in the “fixed sentence condition” the mean proportion correct was 68%, which, although significantly different from the 50% score expected by chance, suggests that the children with CIs found this discrimination task rather difficult. In the “varied sentence condition,” however, the mean proportion correct was only 57%, indicating that the children were essentially unable to recognize an unfamiliar talker's voice when the linguistic content of the paired sentences differed. Correlations with other speech and language outcome measures are also reported.

The World

During the last several decades, cochlear implant has been fully recognized in treatment of severe hearing loss. Development of modern technology enabled inconceivable possibilities of technical qualities of the device as well as development of usable coding strategies, which led to extraordinary results in patient rehabilitation. Although cochlear implantation has become one of the routine operative procedures throughout the world nowadays, it gives rise to certain complications. These complications, though rare, can sometimes be very serious, even with fatal outcome. If cochlear implantation is performed by experienced and well-educated team of experts, the possibility of complications is minimal and is certainly not the argument against cochlear implantation as a method of treatment of severe hearing impairments.

Objectives: The objective of this study was to begin to measure the prevalence of elevated hearing thresholds in Ethiopia, with audiometric equipment, including bone oscillators and tympanometers. To that end Ethiopian nationals were trained in audiometric techniques to obtain sensorineural hearing loss (SNHL) and conductive hearing loss (CHL) rates in school age children. Methods: Five mainstreamed public grade schools in northern Ethiopia were the sites for audiometry campaigns examining 1351 children and testing them with behavioral audiometry. Results: Seven percent of students had SNHL > 20 dB in at least 1 frequency in at least 1 ear, and 0.6% of ears had SNHL > 50 dB. Eighteen percent8% of students had CHL > 20 dB in 1 or both ears. The frequency with the highest incidence of elevated pure tone thresholds was at 8000 Hz. Seven percent of students had an air bone gap at 2000 and/or 4000 Hz of at least 15 dB. Air bone gap is not obtained at 8000 Hz. There were 22 perforated tympanic membranes in 17 children (0.8% of tympanic membranes, 1% of students). Conclusion: This study gives a baseline for the prevalence of hearing loss in school age children in mainstreamed northern Ethiopian schools. It is the first of its kind and perhaps can help in estimated hearing health needs there. Level of Evidence: 2

Referral Criterion

Purpose The goal of this study was to investigate how the use of a 25 dB HL referral criterion in school screenings affects the identification of hearing loss categorized as minimal sensorineural hearing loss (MSHL). Method A retrospective study applied screening levels of 20 and 25 dB HL at 1000, 2000, and 4000 Hz in each ear to previously obtained pure-tone thresholds for 1,475 school-age children. In a separate prospective study, 1,704 children were screened at school under typical conditions, and a subsample had complete audiological evaluations. Referral rates, sensitivity, and specificity were calculated for each screening level. Results Referral rates varied by grade and criterion level, with comparable results between the two data sets. In both studies, when the screening level increased, the sensitivity to MSHL declined markedly, whereas specificity increased in the prospective study. Conclusions Screening at 25 dB yields poor sensitivity to MSHL. Converging evidence from these diverse populations supports using the 20 dB level to help identify MSHL. Multistage screening is recommended to limit referral rates. Even at 20 dB HL, cases of MSHL may be missed. Audiologists should encourage parents, educators, and speech–language pathologists to refer children suspected of hearing difficulty for complete audiological evaluations even if they pass school screenings.
