    OBJECTIVES: Parents of children diagnosed with severe-to-profound sensorineural hearing loss may experience a range of emotions owing to a lack of knowledge and experience in dealing with such children. However, most audiology clinics only attend to children with deaf and hard of hearing (DHH) and not their parents. Thus, parents' emotional and support needs are frequently excluded from the intervention sessions, making their own needs invisible. This study aimed to identify academic and clinical instruments used for assessing parental emotional status (PES) and ecological support systems (ESS) in early intervention and determine the factors affecting PES and ESS among parents of DHH children undergoing cochlear implantation.

    MATERIALS AND METHODS: This scoping review followed the rigorous methodological framework; searched Medline (via OVID and EMBSCO), Scopus, and Web of Science; and selected studies relevant to validated instruments used to evaluate the PES and ESS among parents of DHH children below 6 years old. Before selecting and reviewing relevant articles, two reviewers independently assessed article titles and abstracts from the data sources. Two reviewers verified half of the first reviewer's extracted data.

    RESULTS: Overall, 3060 articles were retrieved from the database search, and 139 were selected for full-text review following title and abstract reviews. Ultimately, this study included 22 articles. Among them, 23 and 12 validated instruments, most of which are generic measures, were used for assessing PES and ESS, respectively. Three condition-specific instruments were identified and designed to be administered following cochlear implantation surgery.

    CONCLUSIONS: This study revealed that healthcare professionals who interact with parents of DHH children lack the necessary instruments, particularly for parents of children undergoing cochlear implantation surgery. Therefore, it is necessary to develop condition-specific instruments for parents who consider cochlear implantation for their children.

    BACKGROUND: This systematic review aimed to identify, compare and contrast outcome domains and outcome instruments reported in studies investigating interventions that seek to restore bilateral (two-sided) and/or binaural (both ears) hearing in adults with single-sided deafness (SSD). Findings can inform the development of evidence-based guidance to facilitate design decisions for confirmatory trials.

    METHODS: Records were identified by searching MEDLINE, EMBASE, PubMed, CINAHL, ClinicalTrials.gov, ISRCTN, CENTRAL, WHO ICTRP and the NIHR UK clinical trials gateway. The search included records published from 1946 to March 2020. Included studies were those as follows: (a) recruiting adults aged 18 years or older diagnosed with SSD of average threshold severity worse than 70 dB HL in the worse-hearing ear and normal (or near-normal) hearing in the better-hearing ear, (b) evaluating interventions to restore bilateral and/or binaural hearing and (c) enrolling those adults in a controlled trial, before-and-after study or cross-over study. Studies that fell just short of the participant eligibility criteria were included in a separate sensitivity analysis.

    RESULTS: Ninety-six studies were included (72 full inclusion, 24 sensitivity analysis). For fully included studies, 37 exclusively evaluated interventions to re-establish bilateral hearing and 29 exclusively evaluated interventions to restore binaural hearing. Overall, 520 outcome domains were identified (350 primary and 170 secondary). Speech-related outcome domains were the most common (74% of studies), followed by spatial-related domains (60% of studies). A total of 344 unique outcome instruments were reported. Speech-related outcome domains were measured by 73 different instruments and spatial-related domains by 43 different instruments. There was considerable variability in duration of follow-up, ranging from acute (baseline) testing to 10 years after the intervention. The sensitivity analysis identified no additional outcome domains.

    CONCLUSIONS: This review identified large variability in the reporting of outcome domains and instruments in studies evaluating the therapeutic benefits and harms of SSD interventions. Reports frequently omitted information on what domains the study intended to assess, and on what instruments were used to measure which domains.

    INTRODUCTION: Restoration of hearing in patients with vestibular schwannoma (VS) and poor hearing poses a great challenge. Simultaneous cochlear implantation during surgery for VS removal offers favorable hearing outcome if the cochlear nerve remains intact. Recent refinement of surgical techniques using the endoscope has made it possible to simultaneously restore the hearing and remove the tumor.

    CASE DESCRIPTION: A 62-year-old male had left severe sensorineural hearing loss and a 4 mm intracanalicular VS. We performed simultaneous nonmastoidectomy infrapromontorial VS removal and cochlear implantation in this patient to achieve minimal invasiveness and to provide maximal hearing restoration. The tumor was removed via this corridor while maintaining the integrity of cochlear as well as facial nerves with full insertion of a medium length cochlear implant electrode. After surgery, the patient showed good hearing rehabilitation.

    CONCLUSION: Simultaneous infrapromontorial VS removal and nonmastoidectomy cochlear implantation serves as an option for hearing restoration with minimal invasiveness in small VS removal.

    INTRODUCTION: Cochlear implant (CI) requires lifelong financial commitments to ensure that the devices always operate optimally.

    OBJECTIVE: We estimated the long-term maintenance costs of CI including repair of speech processors, replacement of damaged parts, and battery requirements.

    RESULTS: Forty-one parents of children who received CIs in Malaysian government hospitals were enrolled. The first 2 years of CI usage were covered by warranty. The cost increased three-fold from by 4 years of CI usage and then doubled by 8 years of usage. About 75% of parents commented that the costs were burdensome.

    CONCLUSION: Our findings will be useful for parents whose children receive CI and will allow medical personnel to counsel the parents about the costs.

    OBJECTIVE: This study aimed to compare the error patterns of Arabic phoneme-grapheme correspondence by a group of Malay children with cochlear implants (CIs) and normal hearing (NH) and the effects of the visual graphical features of Arabic graphemes (no-dot, single-dot, and multiple-dots) on the phoneme-grapheme correspondence.

    METHODS: Participants were matched for hearing age (Mean, M = 7 ± 1.03 years) and duration of exposure to Arabic sounds (M = 2.7 ± 1.2 years). All 28 Arabic phonemes were presented through a loudspeaker and participants pointed to the graphemes associated with the presented phonemes.

    RESULTS: A total of 336 and 616 tokens were collected for six children with CI and 11 NH children for each task, i.e., phonemes repetition and phoneme-grapheme correspondence. Both groups found it easier to repeat phonemes than the phoneme-grapheme correspondence. The children with CIs showed more confusion ([ظ, ز, ذ, ض, خ, ب, ه, س, ع, & ث] >10% correct scores) in phoneme-grapheme correspondence than the NH children ([ظ:14%] and [ث: 27%]). There was a significant interaction (p = 0.001) among the three visual graphical features and hearing status (CI and NH).

    CONCLUSION: Our results infer that non-native Malay children with CIs and NH use different strategies to process the Arabic graphemes' visual features for phoneme-grapheme correspondence.

    OBJECTIVES: This study aimed to report the auditory performance in children with cochleovestibular malformation (CVM)/cochlear nerve deficiency (CND) who were implanted early at the Universiti Kebangsaan Malaysia Medical Centre, using Categorical Auditory Performance (CAP)-II score and Speech Intelligibility Rating (SIR) scales, and to compare the outcome of their matched counterparts.

    MATERIALS AND METHODS: A total of 14 children with CVM/CND with unilateral cochlear implant (CI) implanted before the age of 4 years old were matched and compared with 14 children with normal inner ear structures. Their improvement in auditory performance was evaluated twice using CAP-II score and SIR scales at 6-month intervals, with the baseline evaluation done at least 6 months after implantation.

    RESULTS: The average age of implantation was 31±8 and 33±7 months for the control group and the case (CVM/CND) group, respectively. Overall, there were no significant differences in outcome when comparing the entire cohort of case subjects and their matched control subjects in this study. However, the improvement in CAP-II scores and SIR scales among the case subjects in between the first and second evaluations was statistically significant (p=0.040 and p=0.034, respectively). With longer duration of CI usage, children with CVM/CND showed significant speech perception outcome evident by their SIR scales (p=0.011).

    CONCLUSION: Children with radiographically malformed inner ear structures who were implanted before the age of 4 years have comparable performance to their matched counterparts, evident by their similar improvement of CAP-II scores and SIR scales over time. Hence, this group of children benefited from cochlear implantation.

    OBJECTIVES: The aim of this study was to report on the educational placement, quality of life and speech reception changes in a prospectively recruited group of children after they received a cochlear implant (CI).

    METHOD: Data was collected on 1085 CI recipients of as part of a prospective, longitudinal, observational, international, multi-centre, paediatric registry, initiated by Cochlear Ltd (Sydney, NSW, Australia). Outcome data from children (≤10 years old) implanted in routine practice was voluntarily entered into a central, externally hosted, e-platform. Collection occurred prior to initial device activation (baseline) and at six monthly follow-up intervals up to 24 months and then at 3 years post activation. Clinician reported baseline and follow up questionnaires and Categories of Auditory Performance version II (CAP-II) outcomes were collated. Self-reported evaluation forms and patient information were provided by the parent/caregiver/patient via the implant recipient baseline and follow up, Children Using Hearing Implants Quality of Life (CuHIQoL) and Speech Spatial Qualities (SSQ-P) Parents Version questionnaires.

    RESULTS: Children were mainly bilaterally profoundly deaf, unilaterally implanted and used a contralateral hearing aid. Prior to implant 60% used signing or total communication as their main mode of communication. Mean age at implant was 3.2 ± 2.2 years (range 0-10 years). At baseline 8.6% were in mainstream education with no additional support and 82% had not yet entered school. After three years of implant use, 52% had entered mainstream education with no additional support and 38% had not yet entered school. In the sub-group of 141 children who were implanted at or after three years of age and were thus old enough to be in mainstream school at the three-year follow up, an even higher proportion (73%) were in mainstream education with no support. Quality of life scores for the child improved statistically significantly post implant compared to baseline and continued to improve significantly at each interval up to 3 years (p

    Objective: The value of cochlear implantation (CI) has not been established in Taiwan. The purpose of this study was to evaluate the cost-effectiveness of paediatric CI within the context of Taiwan's national health insurance (NHI) programme.Design: A Markov model-based cost-utility analysis (CUA) was conducted to evaluate the cost-effectiveness of a unilateral CI (UCI) with a contralateral acoustic hearing aid (UCI-HA) compared with a bilateral HA. We performed one-way sensitivity analyses to identify the cost variables that affected the incremental cost-effectiveness ratio (ICER) the most. Monte Carlo simulation was used to explore the simultaneous effect of all uncertain parameters on cost-effectiveness.Study sample: Not applicable.Results: Compared with bilateral HAs, the ICER for UCI-HA was $6487 per quality-adjusted life year (QALY) gained. The ICERs were consistently below $7000 per QALY gained and were most sensitive to the selling price of the external CI device. When this selling price increased by 10%, the ICER of UCI-HA would increase to $6954 per QALY gained. UCI-HA has a probability greater than 50% of being cost-effective if the cost-effectiveness threshold exceeds approximately $10,000 per QALY.Conclusions: Our analysis suggested that within the context of Taiwan's NHI programme, UCI is highly cost-effective for deaf children.

    INTRODUCTION: There has been a paradigm shift in the management of acquired sensory neural deafness in the past 30years. This is due to the emergence of implantable hearing devices such as the cochlear implant. The objective of this study is to identify surgical and functional outcomes of post-lingual and cross-over patients implanted with a cochlear implant under the National Ministry of Heath Cochlear Implant (CI) Program between 2009-2013.

    MATERIALS AND METHODS: We retrospectively reviewed all postlingual and cross-over recipients of cochlear implants under the National Ministry of Heath CI Programme from 2009 to 2013. The outcomes measured were surgical complications and functional outcome. Surgical complications were divided into major and minor complications. Functional outcomes were measured using Categorical Auditory Performances (CAP) scale.

    RESULTS: A total of 41 post-lingual and 15 cross-over patients were implanted between 2009 and 2013. The age of implantees ranged from 3.6 years to 63.2 years old. There were two major complications (3.6%), one is a case of electrode migration at three months post implantation, and six months post second implantation. Another was a case of device failure at about one-year post implantation. Both patients were reimplanted in the same ear. There was no minor complication. The CAP score for both groups (overall) showed significant improvement with 96.4% achieved CAP score of five and above at 24 months after implantation (p<0.001). The CAP score showed marked improvement at the first 6 months post implantation and continued to improve with time in both groups.

    CONCLUSION: The Malaysian National Ministry of Health Cochlear implant (CI) Program between 2009-2013 has been a successful programme with good surgical and functional outcomes among the post lingual and cross-over patients.

    OBJECTIVES: Cochlear implant (CI) greatly enhances auditory performance as compared to hearing aids and has dramatically affected the educational and communication outcomes for profoundly deaf children. Universiti Kebangsaan Malaysia (UKM) pioneered CI program in 1995 in the South East Asia. We would like to report the long-term outcomes of UKM paediatric cochlear implantation in terms of: the proportion of children who were implanted and still using the device, the children's modes of communication, their educational placements, and their functional auditory/oral performance. We also examined the factors that affected the outcomes measured.

    STUDY DESIGN: This was a cross sectional observational study.

    METHODS: Two sets of questionnaires were given to 126 parents or primary caregivers of the implantees. The first set of questionnaire contained questions to assess the children's usage of CI, their types of education placement, and their modes of communication. The second set of questionnaire was the Parent's Evaluation Of Aural/Oral Performance of Children (PEACH) to evaluate the children's auditory functionality.

    RESULTS: Our study showed that among the implantees, 97.6% are still using their CI, 69.8% communicating orally, and 58.5% attending mainstream education. For implantees that use oral communication and attend mainstream education, their mean age of implantation is 38 months. This is significantly lower compared to the mean age of implantation of implantees that use non-oral communication and attend non-mainstream education. Simple logistic regression analysis shows age of implantation reliably predicts implantees (N = 126) would communicate using oral communication with odds ratio of 0.974, and also predict mainstream education (N = 118) with odds ratio of 0.967. The median score of PEACH rating scale is 87.5% in quiet, and this significantly correlates with an earlier age of implantation (r = -0.235 p = 0.048).

    CONCLUSIONS: UKM Cochlear Implant Program has achieved reasonable success among the pediatric implantees, with better outcomes seen in those implanted at the age of less than 4 years old.

    Evidence of ossification was previously considered a relative contraindication to cochlear implantation. It was considered difficult or impossible to achieve safe electrode insertion because of bony obstruction. Either the electrodes or the inner ear structures could be damaged. Moreover, obstructed scala tympani could limit the number of electrodes that can be inserted. The efficacy of the electrical stimulation was also questioned, as a higher current would be needed on an ossified cochlea. Finally, the neural survival in ossified cochlea is unknown. This may complicate the surgical procedure and affect the long-term outcome. However, depending on the experience of the surgeon, cochlear implantation has been attempted even in grossly ossified cochlea. Here we illustrate that cochlear implantation is safe in labyrinthitis ossificans.

    The study aimed to develop Mandarin speech perception tests for Malaysian Chinese children. Two tests were developed which were the Syllabic Pattern Perception Test (SPPT) and the Tone Perception Test (TPT). Both tests were designed for children aged between three to six years-old. A total of 80 normal hearing children aged 3 years to 6 years and 11 months from several kindergartens around Kuala Lumpur and Ipoh participated in this study. Results showed that the mean scores for the SPPT did not differ significantly across age (p > 0.05), possibly due to a ceiling effect. Although the SPPT showed relatively low test-retest and inter-rater Spearman correlation coefficients (r = 0.68 for correct syllable pattern response and r = 0.38 for correct item response), the scores were highly repeatable in both test-retest and interrater conditions. For the TPT, the mean scores of five and six year old children were significantly higher than three year old subjects while the mean score of four year old subjects was significantly poorer than the six years old. The test-retest and inter-rater reliability were high and the coefficients approximated 0.80 (p < 0.05). For both tests, gender and dialects or languages used as the second language did not have significant effect on the test scores. Content validity evidence was also collected from a group of panelists. In conclusion, SPPT and TPT are reliable and valid Mandarin speech tests to be used on Malaysian Chinese children who speak Mandarin.

    Many children have benefited from cochlear implant device including those with congenital malformation of the inner ear. The results reported in children with malformed cochlea are very encouraging. We describe 2 cases of Mondini's malformation with severe sensorineural hearing loss. Cochlear implantation was performed and both of them underwent post-implantation speech rehabilitation. Post-implantation, both of them were noted to respond to external sound. But the second case developed facial twitching a few months after the device was switched on. It is important to evaluate the severity of the inner ear deformity and the other associated anomalies in pre-implantation radiological assessment in order to identify the problem that may complicate the surgery and subsequent patient management.

    OBJECTIVE: This study examined the patterns of recognition of Arabic consonants, via information transmission analysis for phonological features, in a group of Malay children with normal hearing (NH) and cochlear implants (CI).

    METHOD: A total of 336 and 616 acoustic tokens were collected from six CI and 11 NH Malay children, respectively. The groups were matched for hearing age and duration of exposure to Arabic sounds. All the 28 Arabic consonants in the form of consonant-vowel /a/ were presented randomly twice via a loudspeaker at approximately 65 dB SPL. The participants were asked to repeat verbally the stimulus heard in each presentation.

    RESULTS: Within the native Malay perceptual space, the two groups responded differently to the Arabic consonants. The dispersed uncategorized assimilation in the CI group was distinct in the confusion matrix (CM), as compared to the NH children. Consonants /ħ/, /tˁ/, /sˁ/ and /ʁ/ were difficult for the CI children, while the most accurate item was /k/ (84%). The CI group transmitted significantly reduced information, especially for place feature transmission, then the NH group (p

    OBJECTIVES: The aims of the study were to compare the mainstream school readiness skills of young cochlear implant (CI) users to that of a group of normal hearing (NH) children and assessed the inter-rater agreement between parents and teachers on school readiness skills of the CI children.

    METHODS: A total of 11 parents and 8 teachers of the 6-year old CI children participated and rated the children using the School Readiness Scale to Year One. Data from 207 6-year old NH children from five states in Malaysia were also collected using the same scale which has nine domains. Results from the NH children were categorized into the 25th and 75th percentile scores to be the reference cut-offs for below average (below the 25th percentile), average (25th to 75th percentile) and above average (above 75th percentile).

    RESULTS: The school readiness skills of the CI children were lower than the NH group as rated by teachers especially in the civic and language and communication domains. Comparisons between parents' and teachers' ratings for 8 CI children indicated that teachers tended to rate the CI children's school readiness poorer than that of parents especially in the academic domain. Intra-class correlation analysis revealed poor inter-rater agreement.

    CONCLUSIONS: The results suggest that our CI children, generally, need an intervention 'bridging' program to improve their school readiness skills. Parents and teachers had different views on the readiness of the CI children at school entry level.

    OBJECTIVES: This study aimed to describe the factors affecting early and late cochlear implantation.

    MATERIALS AND METHODS: A total of 159 patients from the Hospital Canselor Tuanku Muhriz (HCTM) Cochlear Implant Programme were recruited in this retrospective cross-sectional study. All paediatric Cochlear Implant (CI) recipients with pre-lingual deafness were included in this retrospective study. The study was conducted from January 2019 until December 2020. The pre-lingual cochlear implant recipients' data were analysed based on demographics and interval from diagnosis to hearing aid fitting and implantation. The association between the dependent variables with early and late cochlear implantation was compared.

    RESULTS: A total of 83 (52%) patients were female. Chinese race constituted most of the patients, which was 90/159 (57%). The majority were from middle-income families (M40); 89 (56%). The most common aetiology of Hearing Loss (HL) was idiopathic; 139 (87%), followed by intrauterine infections, which comprised of congenital CMV; 8 (5%) and congenital Rubella; 1 (1%) and nonspecific intrauterine infection 2 (1%). The relationship between the universal neonatal hearing screening and the interval between diagnosis to implantation was significant (p=0.033). Other variables were not significant.

    CONCLUSION: UNHS was a significant factor contributing to early and late implantation. The median age of diagnosis of hearing loss was 18 months (interquartile range; 15); the age of CI was 34 months (interquartile range; 24); the interval from diagnosis to hearing aid was 2 months (interquartile range; 5), and the interval from diagnosis to CI was 16 months (interquartile range; 14).

    Auditory brainstem implantation (ABI) is the only solution to restore hearing when cochlear nerves are disrupted together with the pathologies where bilateral cochleae do not provide a suitable location for cochlear implantation. We reported first two successful auditory brainstem implantation cases in patients with neurofibromatosis Type II (NF2) with bilateral acoustic neuroma causing bilateral profound sensorineural hearing loss in Malaysia. A good candidate selection, dedicated surgeons and rehabilitation team as well as strong family support are the crucial factors in achieving the best possible surgical, audiological and speech outcomes.

    OBJECTIVE: To determine the cost-effectiveness of cochlear implantation (CI) with mainstream education and deaf education with sign language for treatment of children with profound sensorineural hearing loss in low- and lower-middle income countries in Asia.

    STUDY DESIGN: Cost-effectiveness analysis.

    SETTING: Bangladesh, Cambodia, India, Indonesia, Nepal, Pakistan, Philippines, and Sri Lanka participated in the study.

    SUBJECTS AND METHODS: Costs were obtained from experts in each country with known costs and published data, with estimation when necessary. A disability-adjusted life-years model was applied with 3% discounting and 10-year length of analysis. A sensitivity analysis was performed to evaluate the effect of device cost, professional salaries, annual number of implants, and probability of device failure. Cost-effectiveness was determined with the World Health Organization standard of cost-effectiveness ratio per gross domestic product (CER/GDP) per capita <3.

    RESULTS: Deaf education was cost-effective in all countries except Nepal (CER/GDP, 3.59). CI was cost-effective in all countries except Nepal (CER/GDP, 6.38) and Pakistan (CER/GDP, 3.14)-the latter of which reached borderline cost-effectiveness in the sensitivity analysis (minimum, maximum: 2.94, 3.39).

    CONCLUSION: Deaf education and CI are largely cost-effective in participating Asian countries. Variation in CI maintenance and education-related costs may contribute to the range of cost-effectiveness ratios observed in this study.
