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.

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.

Auditory Performance

Mucopolysaccharidosis IVA (OMIM 253000; also known as Morquio A syndrome) is associated with skeletal, airway, and hearing abnormalities. Cochlear implantation is an effective intervention for patients with severe-to-profound hearing loss. Patients can gain substantial improvement in auditory performance, speech perception, and their quality of life from cochlear implantation. Although severe progressive sensorineural hearing loss is a common feature of mucopolysaccharidosis IVA, no detailed description of cochlear implantation for mucopolysaccharidosis IVA has been reported. To review the effectiveness and special considerations associated with cochlear implantation in patients with mucopolysaccharidosis IVA, we here report the case of cochlear implantation in mucopolysaccharidosis IVA by a multidisciplinary team. A retrospective chart review was conducted on a 34-year-old female with mucopolysaccharidosis IVA, who received a cochlear implant. Audiometric thresholds, speech perception scores, and cochlear implant processor mapping information were reviewed during the first 12 months following cochlear implantation. The results of audiological tests indicate improved hearing thresholds as well as remarkable enhancement of speech perception skills over 12 months of cochlear implant use. Cochlear implantation improved auditory performance in a mucopolysaccharidosis IVA patient with postlingually severe-to-profound sensorineural hearing loss. The benefits of cochlear implantation could be meaningful for other Morquio patients with progressive hearing loss, although the risks of surgery and anesthesia should be carefully considered by a multidisciplinary team of experts during the cochlear implant candidacy process.

The Impact

Relevance: Any kind of the hearing loss, especially in the childhood, affects the mental and intellectual development negatively as well as behavior and social position of a deaf patient in the hearing world. Cochlear implantation is the most effective and reliable method of medical and educational auditory-speech rehabilitation for both adults and children with severe hearing loss and deafness. One of the key performance indicators of the cochlear implantation is a result of speech audiometry, especially on the noise background. The aim is to study the state of auditory function according to the subjective audiometry in the noise background and the influence of various factors on the effectiveness of rehabilitation of the children after cochlear implantation. Materials and methods: The study involved 150 children with severe sensorineural hearing loss and deafness after cochlear implantation. In age, they ranged from 3 to 18 years old. Evaluation of the efficiency of cochlear implantation was carried out in several stages. All studies were done in the free-field with the cochlear implant on. At first, we performed the pure tone audiometry. Then we defined the 50% intelligibility threshold of numeral test. After that, we defined a word recognition percentage. And finally we defined the impact of masker on speech intelligibility at SPL of useful signal 50, 60 and 80 dB. Results: Based on the analysis of the received data, all children with severe sensorineural hearing loss and deafness after cochlear implantation were divided into 3 groups depending on the speech intelligibility. The first group (high efficiency of cochlear implantation) included 68 children (45,3%). This group was divided into two subgroups depending on the difference between the values of the speech intelligibility in the free sound field and in the noise background. The second group (average efficiency) consisted of 45 children (30%). The third group (low efficiency) were 37 children (24,7%). The influence of various factors on the efficiency of cochlear implantation was analyzed. Conclusion: Speech intelligibility in the noise background must be examinated in all children after cochlear implantation. The main factors affecting the effectiveness of cochlear implantation according to test of speech intelligibility in the noise background are the ethiology of hearing loss and duration of post-operation period. Results of speech intelligibility in the noise background test will help specialists who practice the rehabilitation of children after cochlear implantation (teachers for deaf, speech therapists) to pay attention to the decrease of speech intelligibility in children in the real conditions of communication and to focus their efforts on its improving with the appropriate methods.
