Background: The otosclerotic process may influence the performance of the cochlear implant (CI). Difficulty in inserting the electrode array due to potential ossification of the cochlea, facial nerve stimulation, and instability of the results are potential challenges for the CI team. Objectives: To evaluate hearing results and subjective outcomes of CI users with otosclerosis and to compare them with those of CI users without otosclerosis. Method: Retrospective review of 239 adults with bilateral profound postlingual deafness who underwent unilateral cochlear implantation between 1992 and 2017. Hearing and speech understanding were assessed via pure-tone audiometry and speech perception tests. Subjective outcomes were assessed via the Nijmegen Cochlear Implant Questionnaire (NCIQ), the Glasgow Benefit Inventory (GBI), and the Hearing Implant Sound Quality Index (HISQUI19) at 6 months, 12 months, and at the last follow-up. Results: Subjects were 22 CI users with otosclerosis and 217 without otosclerosis. Both groups had a similar duration of deafness and age at CI implantation. Results did not significantly differ according to group: no significant intergroup difference was found regarding the frequency of complete electrode insertion, facial stimulation, reimplantation, or PTA4 scores at the last follow-up. Regarding speech perception, no significant intergroup difference was found on any test or at any interval. Further, subjective outcomes, as measured by the GBI, NCIQ, and HISQUI19, did not significantly differ between groups. Conclusions: Adults with otosclerosis and profound hearing loss derive significant benefit from CI use. Audiological and self-reported outcomes are not significantly different from that of other CI users with postlingual deafness.

The Nucleus 24 Contour is a new cochlear implant that has recently undergone clinical trials in adults and children. The Contour uses the same electronics as the previous-generation Nucleus 24 (CI24M) but incorporates a downsized receiver-stimulator and a perimodiolar electrode array. The indications for use were expanded to include children as young as 12 months of age and children 24 months of age and older with severe to profound hearing loss who had open-set word recognition up to 30%. The Contour was successfully implanted in 256 children. The mean level of postoperative speech perception with the Contour was significantly better than the preoperative baseline with hearing aids on all measures. Children who had open-set speech perception in an audition-only condition before surgery demonstrated higher levels of postoperative performance with the Contour than children with no open-set speech perception before surgery.

Abstract Introduction Patients with vestibular schwannomas (VS) must have formal audiology during their workup, according to multiple national guidelines (including NICE). Method This retrospective study sought to audit the percentage of VS cases undergoing formal audiometry at a tertiary neurosurgical centre. An illustrative sample was selected randomly from local databases (2006-2019). Data collected included audiometry types (speech discrimination [SD], pure tone audiometry [PTA]), management pathway (surgery, radiotherapy or conservative) and symptom profile. Results 200 cases were assessed, 7 were excluded (private patients, patients referred but not formally seen). Of the 193 cases included, 186 (96.4%) had ≥1 Pure Tone assessment [PTA], with 135 (70%) also tested on Speech Discrimination [SD]. The surgical cohort had the highest audiometry rates at 38/38, followed by 116/121 (96%) for surveillance and 32/34 (94%) for radiotherapy subgroups. Reasons for no audiology were: profound hearing loss at presentation (2/7), audiometry at local centres (4/7) and patient compliance (1/7). Conclusions Our service is highly compliant (96.4%), consistent across management categories. The rate of SD (70%), a functional measure of hearing impairment, can be improved. Monitoring surgical outcomes via formal audiometry should be standard, particularly surgical approaches that preserve hearing are chosen. Follow-up audiometry regimes can be standardized for those on surveillance pathways.

Background: A prospective longitudinal multicentre study was conducted to assess the one-year postsurgical hearing preservation profile of the EVOTM electrode array. Methods: Fifteen adults presenting indications of electro-acoustic stimulation (pure-tone audiometry (PTA) thresholds ≤70 dB below 750 Hz) were implanted with the EVO™ electrode array. Hearing thresholds were collected at five time-points from CI activation to twelve months (12M) after activation. Hearing thresholds and hearing preservation profiles (HEARRING group classification) were assessed. Results: All subjects had measurable hearing thresholds at follow-up. No case of complete loss of hearing or minimal hearing preservation was reported at any time point. At activation (Nact = 15), five participants had complete hearing preservation, and ten participants had partial hearing preservation. At the 12M time point (N12m = 6), three participants had complete hearing preservation, and three participants had partial hearing preservation. Mean hearing loss at activation was 11 dB for full range PTA and 25 dB for PTAs low-frequency (125–500 Hz). Conclusions: This study provides the first longitudinal follow-up on associated hearing profiles to the EVO™ electrode array, which are comparable to the literature. However, other studies on larger populations should be performed.

As the indications for cochlear implant have expanded to include younger patients and individuals with greater degrees of residual hearing, increasing emphasis has been placed on atraumatic surgery and the preservation of the cochlear structure. Here, a descriptive prospective randomized study was performed. It was shown that residual hearing preservation is possible 12 months postoperatively with an atraumatic perimodiolar flexible electrode array CI532® (Cochlear Ltd, Sydney, Australia). Residual hearing preservation, considered as < 15 dB, was obtained in 70% of the cases. Better clinical outcomes and performance could be obtained compared with the previous perimodiolar CI512®, but further research and a longer follow-up are necessary to verify the impact of outcomes.

Objectives: This study analyzed the predictability of fitting levels for cochlear implant recipients based on a review of the clinical levels of the recipients. Design: Data containing threshold levels (T-levels) and maximum comfort levels (M-levels) for 151 adult subjects using a CII/HiRes 90K cochlear implant with a HiFocus 1/1 J electrode were used. The 10th, 25th, 50th, 75th and 90th percentiles of the T- and M-levels are reported. Speech perception of the subjects, using a HiRes speech coding strategy, was measured during routine clinical follow-up. Results: T-levels for most subjects were between 20 and 35% of their M-levels and were rarely (<1/50) below 10% of the M-levels. Furthermore, both T- and M-levels showed an increase over the first year of follow-up. Interestingly, levels expressed in linear charge units showed a clear increase in dynamic range (DR) over 1 year (29.8 CU; SD 73.0), whereas the DR expressed in decibels remained stable. T-level and DR were the only fitting parameters for which a significant correlation with speech perception (r = 0.34, p < 0.01, and r = 0.33, p < 0.01, respectively) could be demonstrated. Additionally, analysis showed that T- and M-level profiles expressed in decibels were independent of the subjects' across-site mean levels. Using mixed linear models, predictive models were obtained for the T- and M-levels of all separate electrode contacts. Conclusions: On the basis of the data set from 151 subjects, clinically applicable predictive models for T- and M-levels have been obtained. Based on one psychophysical measurement and a population-based T- or M-level profile, individual recipients' T- and M-levels can be approximated with a closed-set formula. Additionally, the analyzed fitting level data can serve as a reference for future patients. i 2014 S. Karger AG, Basel

Viable Treatment

Cochlear implantation is a viable treatment for patients with severe to profound hearing loss. We report the results of speech perception tests (numbers, monosyllables, and sentence tests) achieved with MED-EL's COMBI 40+ (C40+) cochlear implant after 12 months of use. These findings, which were taken from a larger German study, were similar to those of other studies of the C40+ implant. We also compared the differences in speech perception observed with the CIS PRO+ body-worn speech processor and the newer TEMPO+ behind-the-ear speech processor. Although these results were similar with respect to most of the measured parameters, the TEMPO+ processor had a distinct advantage during tests in noise.

Purpose In this article, the authors describe current pediatric cochlear implant (CI) assessment and postoperative scheduling protocols in the United States. Method A survey was conducted in 2 phases. Results Response rates were similar between Phase I (10%) and Phase II (13%). Across phases, nearly all respondents reported assessing speech perception both preoperatively and postoperatively. The most frequently used parent questionnaires were the Infant–Toddler Meaningful Auditory Integration Scale (Robbins, Renshaw, & Berry, 1991), the Meaningful Auditory Integration Scale (Robbins et al., 1991), and LittlEARS (Kuehn-Inacken, Weichboldt, Tsiakpini, Coninx, & D'Haese, 2003). The most commonly used speech perception measure for children <23 months of age was the Early Speech Perception Test–Low Verbal (ESP-LV; Moog & Geers, 1990). The most commonly used measures for children 24–35 months of age were the ESP-LV, the Northwestern University of Children's Perception of Speech (Elliot & Katz, 1980), and the Mr. Potato Head task (Robbins, 1993). For children >36 months of age, there was a wide variety of speech perception tests utilized. Patient follow-up visits were weekly or biweekly immediately following CI activation, then every 3 months for the remainder of the 1st year. After the 1st year, most children were seen semiannually. Conclusions Although trends emerged, there is a lack of consistency in the selection of speech perception measures utilized across centers for children <36 months of age. The development of a working group to establish a standard minimum pediatric test battery (similar to the adult Minimum Speech Test Battery) would promote uniformity in clinical protocols used to assess children who receive CIs.

The Mean

Speech perception outcomes for early-deafened children who undergo implantation as teenagers or young adults are generally reported to be poorer than results for young children. It is important to provide appropriate expectations when counseling adolescents and their families to help them make an informed choice regarding cochlear implant surgery. The considerable variation of results in this group makes this process more difficult. This study considered a number of factors in a group of 25 children who underwent implantation in Melbourne between the ages of 8 and 18 years. Each subject completed open-set speech perception testing with Bamford-Kowal-Bench sentences before and after implantation and preoperative language testing with the Peabody Picture Vocabulary Test. Data were collected regarding the type of hearing loss, age at implantation, age at hearing aid fitting, audiometric details, and preoperative and postoperative communication mode. Results were submitted to a stepwise multiple linear regression analysis with postoperative open-set sentence scores as the dependent variables. The analysis suggested that 3 factors have a significant predictive value for speech perception after implantation: preoperative open-set sentence score, duration of profound hearing loss, and equivalent language age. These 3 factors accounted for 66% of the variance in this group. The results of this study suggest that children who have useful speech perception before implantation, and higher age-equivalent scores on language measures, would be expected to do well with a cochlear implant. Consistent with other studies, a shorter duration of profound hearing loss is also advantageous. The mean sentence score for this group, 47%, was not significantly different from the mean result across all children in the Melbourne program.
