Profound hearing loss makes it difficult for a person to fully integrate into society. Cochlear implantation is rightfully considered a universal and an effective method of rehabilitation of patients with severe and profound hearing loss. The advantages of binaural hearing are well known; the advantages of bilateral cochlear implantation over monolateral implantation are undeniable, due to the restoration of all binaural hearing effects. At the moment, the relevance of simultaneous cochlear implantation, especially among children, and its benefits compared with sequential implantation are being discussed. It is known that there are special groups of patients among patients with hearing loss; they are either unrehabilitated at all or rehabilitation measures for which are ineffective. Special patient groups include patients with unilateral acquired or congenital deafness, asymmetric and residual hearing loss. Patients in these groups often complain of poor speech intelligibility, especially against a background of noise, inability to localize the source of sound, one-sided or two-sided tinnitus, and, as a result, a deterioration in the quality of life. All abovementioned makes us think about the need to revise the indications for cochlear implantation and study this issue in detail.

Objective. To describe the audiological, anesthesiological, and surgical key points of cochlear implantation after bacterial meningitis in very young infants.Material and Methods. Between 2005 and 2010, 4 patients received 7 cochlear implants before the age of 9 months (range 4–8 months) because of profound hearing loss after pneumococcal meningitis.Results. Full electrode insertions were achieved in all operated ears. The audiological and linguistic outcome varied considerably, with categories of auditory performance (CAP) scores between 3 and 6, and speech intelligibility rating (SIR) scores between 0 and 5. The audiological, anesthesiological, and surgical issues that apply in this patient group are discussed.Conclusion. Cochlear implantation in very young postmeningitic infants is challenging due to their young age, sequelae of meningitis, and the risk of cochlear obliteration. A swift diagnostic workup is essential, specific audiological, anesthesiological, and surgical considerations apply, and the outcome is variable even in successful implantations.

Introduction: Although it is recommended to perform cochlear implantation in both ears at the same time for management of profound hearing loss in children, many centers prefer to perform sequential implantation. There are many reasons as to why a simultaneous bilateral implantation is not commonly accepted and performed. The major risk is the possibility of bilateral vestibular organ impairment. However, it is beyond doubt that children who received the first implant should be given a chance for binaural hearing and associated benefits. In the literature, there are no homogenous criteria for bilateral implantation, and it is hard to find uniform and convincing algorithms for second cochlear implantation. The aim of this study is an attempt to identify a safe way of qualifying for second cochlear implantation in children. Material and methods: Forty children with one cochlear implant were qualified for the second implantation. During qualification, the following were taken into account: time of the first implantation, audiometry results, use of the hearing aid in the ear without an implant and benefit of the device, speech and hearing development, and vestibular organ function. R esults: Fifteen out of forty children (38%) were qualified for the second implantation. In 35% of children, the decision was delayed with possible second implantation in the future. Eleven children (27%) were disqualified from the second surgery. Discussion: During evaluation according to the protocol presented in our study, 38% of children with a single cochlear implant were qualified for the second implantation with a chance for an optimal development and effective use of the second cochlear implant. We are convinced that sequential implantation with a short interval between surgeries and with an examination of the vestibular organ, hearing and speech development as well as an assessment of potential benefits from the second implant (bimodal stimulation) before the second implantation is the safest and most beneficial solution for children with severe hearing loss.

Profound Hearing Loss

Profound hearing loss affects thousands of people in the United States and the United Kingdom, with a higher incidence among people of low socioeconomic status. A cochlear implant is a surgically implanted device that has been demonstrated to improve communication and quality of life among profoundly hearing-impaired individuals. This review postulates that the rate of cochlear implantation among eligible candidates can be used to assess quality of healthcare, with a view toward examining disparities in healthcare services both in American free-market system and in the British National Health Service. A systematic literature search was performed for pertinent articles investigating socioeconomic status and cochlear implantation. Data from twenty-two sources were analyzed, and it was shown that-despite differences in the healthcare systems of the United States and England-similar trends are apparent in the two countries with regard to a lower rate of pediatric cochlear implantation surgery in children with profound hearing loss as familial socioeconomic status decreases.

Release From Masking

Bilateral cochlear implantation is increasing worldwide. In adults, bilateral cochlear implants (BICI) are often performed sequentially with a time delay between the first (CI1) and the second (CI2) implant. The benefits of BICI have been reported for well over a decade. This study aimed at investigating these benefits for a consecutive sample of adult patients. Improvements in speech-in-noise recognition after CI2 were followed up longitudinally for 12 months with the internationally comparable Finnish matrix sentence test. The test scores were statistically significantly better for BICI than for either CI alone in all assessments during the 12-month period. At the end of the follow-up period, the bilateral benefit for co-located speech and noise was 1.4 dB over CI1 and 1.7 dB over CI2, and when the noise was moved from the front to 90 degrees on the side, spatial release from masking amounted to an improvement of 2.5 dB in signal-to-noise ratio. To assess subjective improvements in hearing and in quality of life, two questionnaires were used. Both questionnaires revealed statistically significant improvements due to CI2 and BICI. The association between speech recognition in noise and background factors (duration of hearing loss/deafness, time between implants) or subjective improvements was markedly smaller than what has been previously reported on sequential BICI in adults. Despite the relatively heterogeneous sample, BICI improved hearing and quality of life.

AbstractBackgroundThis study investigated health-related quality of life outcomes for children with cochlear implants in India using the Glasgow Children's Benefit Inventory questionnaire. Cochlear implantation is associated with improved language outcomes. Some studies show this gives higher quality of life after implantation. Previous research demonstrates that India presents unique circumstances that impact perspectives regarding cochlear implantation.MethodChildren (aged under 18 years) who had undergone cochlear implantation were recruited from Vani Pradan Kendra, an organisation for individuals with hearing loss based in Bangalore, India. Demographic data including age, sex, duration of hearing loss and age at implant were collected, and the children's parents or caregivers completed the Glasgow Children's Benefit Inventory questionnaire.ResultsSixty-nine children (mean age: 8.0 ± 3.89 years) were recruited, and all reported improved quality of life after cochlear implantation. There was no effect of age, gender or education on reported benefits. However, a younger age at implant and longer experience with an implant were associated with greater quality of life improvements.ConclusionCochlear implantation leads to improved quality of life, with greater improvements associated with earlier implantation. This supports early intervention in children with profound hearing loss.

Abstract Purpose In clinical trials and everyday medical practice, health-related quality of life (HRQoL) measures are increasingly being used. That is, in addition to the usual biological health assessment, the impact of disease and treatment on the patient’s functioning in the physical, mental, and social areas is an important parameter. The aim of this study was to assess HRQoL before and after using a cochlear implant (CI) in adults with profound hearing loss. Methods There were 104 patients who qualified for the study. All gave informed and free consent. The study involved adults with bilateral hearing loss above 81 dB HL and rated according to the World Health Organization (WHO) classification scheme as having profound hearing loss (which includes deafness). In each participant, the hearing loss was postlingual, that is, it occurred after speech and language had developed. The assessment of quality of life (AQoL-8D) questionnaire was used to assess the health-related quality of life in the study participants. Results Quality of life significantly increased (p < 0.001) after cochlear implantation in almost all domains (except the pain dimension). The mean increase in overall quality of life was 0.16, the greatest improvement was found in the dimensions senses (mean change of 0.17) and self-worth (mean change of 0.16). Conclusion Cochlear implantation improves the health-related quality of life of the postlingually deaf.

<b><i>Introduction:</i></b> Audiovestibular symptoms are rare in sarcoidosis, but they may also be the first manifestation of the disease. Sudden or progressive bilateral hearing loss is usually associated with vestibular impairment. The mechanism of hearing loss remains unclear, but clinical presentation and magnetic resonance imaging suggest a retrocochlear site for the lesion in most patients. Several cases of hearing recovery after corticosteroid treatment have been reported. In patients with severe or profound hearing loss, the benefit of cochlear implantation is challenging to predict in the case of auditory neuropathy and is rarely described. We present a case series of cochlear implantation in patients with documented neurosarcoidosis. <b><i>Results:</i></b> Seven cases of cochlear implantation in 4 patients with neurosarcoidosis are reported. All of the patients showed a great improvement very quickly in both quiet and noise. Speech performance remained stable over time with a follow-up ranging from 4 to 11 years, even in patients who had disease exacerbation. <b><i>Conclusion:</i></b> Cochlear implantation is possible in deaf patients with neurosarcoidosis. The excellent benefit obtained in our patients suggests a particular type of neuropathy, but endocochlear involvement cannot be entirely ruled out.

Background: Bacterial meningitis is one of the major factors in the etiology of acquired sensorineural hearing loss in children and adults. Cochlear implantation in these patients is challenging because of inner ear ossification and fibrosis, and this procedure sometimes achieves poorer outcomes in this scenario than with other causes of sensorineural hearing loss. There has been little research into the factors affecting the outcomes of this procedure. Objective: To evaluate the outcomes of cochlear implantation in patients with postmeningitis profound sensorineural hearing loss and to evaluate the factors that affect the results. Materials and Methods: A retrospective review was conducted of thirty patients who were diagnosed with post meningitis profound hearing loss and underwent cochlear implantation at Rajavithi Hospital between 2001 and 2016. Preoperative language status, duration of deafness, preoperative imaging, and degree of electrode insertion were recorded. Categories of auditory performance-II test (CAP-II) was evaluated in all cases, one year postoperative. Results: Thirty postmeningitis deafness patients underwent cochlear implantation. The median age at diagnosis of meningitis and age at implantation were 41 years (range 1 to 75) and 49.50 years (range 3 to 75), respectively. The median duration of deafness was 12 months (range 4 to 300), and the overall mean CAP-II at one year after surgery was 5.47±2.21. The postlinguistic group had a significantly higher CAP-II score than the prelinguistic one (p=0.006). Electrodes were successfully totally inserted in 19 patients (63.3%) and partially inserted in 11 (36.7%). The average CAP-II score in the group with fully-inserted electrodes was significantly higher than in the group with partially-inserted electrodes (p=0.045). There was no correlation between CAP-II score and age at meningitis diagnosis (p=0.069), age at time of surgery (p=0.105), duration of deafness (p=0.506), or preoperative CT (p=0.228) or MRI abnormality (p=0.078). Conclusion: Cochlear implantation in patients with postmeningitis profound hearing loss had high success rates and favorable outcomes. Preoperative language status and degree of electrode insertion were factors that affected auditory performance results.
