Ct Studies

Preoperative temporal bone computed tomography (CT) can demonstrate anatomic details relevant to surgical management and is therefore essential in the presurgical evaluation of patients receiving cochlear implants. The purpose of this study was to evaluate preoperative CT studies and compare them to surgical findings in 34 children who received the Nucleus multichannel cochlear implant. The focus of this report is to discuss the dependability of CT scans in predicting surgical findings at the time of cochlear implantation. Results indicate that agreement of CT interpretations with surgical findings is partially related to the etiology of hearing loss and the experience of the surgeon and neuroradiologist. Advantages and limitations of the CT scans in predicting surgical findings are discussed.

Device Failure

Cochlear implantation is considered to be a safe and effective treatment for severe to profound sensorineural hearing loss. Device failures are rare. We report the cases of 2 patients—a 44-year-old woman and a 3-year-old boy—with cochlear implants who were referred to our tertiary cochlear implant center for treatment of magnet migration secondary to mild head trauma. The migration had led to device failure in both cases. Surgical re-exploration was performed with nonmagnetic instruments, and both magnets were easily returned to their proper place. Postoperatively, implant function was restored to previous levels, and wound healing was uncomplicated. The incidence of magnet migration in cochlear implant patients is unknown. A few cases have been reported in children, but to the best of our knowledge, ours is the first report of magnet migration in an adult.

Cochlear implants have transformed the treatment of sensorineural hearing loss. They have few major complications. The authors describe the case of a man fitted with a cochlear implant who suffered a postoperative subdural haematoma. The haematoma is thought to have been caused by bleeding from emissary veins opened by the drill passages used to anchor the sutures for the receiver/stimulator. The authors have abandoned tie down sutures in cochlear implants, preferring an appropriately deep well with squared-off rims, which would secure the implant in place. They have had no further complications of this nature.

AbstractObjective:Description of two siblings with unexplained, progressive, perceptive hearing loss after head trauma.Design:Case report.Subjects:Two siblings aged six and eight years old with bilateral, intermittent but progressive hearing loss.Results:These patients had a c.1172G>A (p.Ser391Asn) mutation in the SLC26A4 gene, which has not previously been reported and which caused Pendred or enlarged vestibular aqueduct syndrome. The diagnosis was based on the perceptive hearing loss, computed tomography findings and mutation analysis. The patients were each fitted with a cochlear implant because of their severe, progressive, perceptive hearing loss with deep fluctuations. The results were good.Conclusion:Further testing for the presence of an enlarged vestibular aqueduct is recommended when children present with sudden progression in perceptive hearing loss, whether or not in combination with head trauma. Cochlear implantation is indicated in patients with persistent, progressive hearing loss that leads to deafness. Implantation can be undertaken successfully despite cochlear hypoplasia.

AbstractObjective:This study aimed to define the characteristics and use of ocular and cervical vestibular evoked myogenic potentials for evaluating paediatric cochlear implant candidates.Methods:Ocular and cervical vestibular evoked myogenic potentials of 34 paediatric cochlear implant candidates were analysed. All patients also underwent a routine audiological examination, including computed tomography.Results:In all, 27 patients with normal inner-ear structures had absent or impaired vestibular evoked myogenic potential responses. In paediatric candidates with inner-ear malformations, ocular and cervical vestibular evoked myogenic potentials had lower thresholds and higher amplitudes. Vestibular evoked myogenic potential responses in this cohort were classified into three groups. There was significant concordance between vestibular evoked myogenic potentials and temporal bone computed tomography findings.Conclusion:Ocular and cervical vestibular evoked myogenic potential waveforms were different in paediatric candidates with normal and abnormal inner-ear structures. Therefore, vestibular evoked myogenic potential responses can indicate temporal bone structure.

The Relationship

Understanding genetic causes of hearing loss can determine the pattern and course of a patient’s hearing loss and may also predict outcomes after cochlear implantation. Our goal in this study was to evaluate genetic causes of hearing loss in a large cohort of adults and children with cochlear implants. We performed comprehensive genetic testing on all patients undergoing cochlear implantation. Of the 459 patients included in the study, 128 (28%) had positive genetic testing. In total, 44 genes were identified as causative. The top 5 genes implicated were GJB2 (20, 16%), TMPRSS3 (13, 10%), SLC26A4 (10, 8%), MYO7A (9, 7%), and MT-RNR1 (7, 5%). Pediatric patients had a higher diagnostic rate. This study lays the groundwork for future studies evaluating the relationship between genetic variation and cochlear implant performance.

The article considers the rehabilitation problem of children with hearing loss who have cochlear implants. The main aspects of detecting hearing loss of different degrees, providing early help, and a modern method of hearing aid — cochlear implantation are described. The leading indicators of hearing development of a child after cochlear implantation and the importance of an integrated approach in rehabilitation are revealed. It is noted that a child with a cochlear implant can communicate with others, hear them and understand. However, this method is critical to use in the first three years of a child’s life to develop speech and hearing centres of the brain. In this case, with the help of a cochlear implant, the child will learn to perceive the language of others, use language for communication and develop along with peers, and accordingly socialize.The article emphasizes the importance and necessity of training specialists to rehabilitate such children, the introduction into the educational process of correctional programs for the development of auditory perception after cochlear implantation, development of guidelines for professionals and parents, educational and rehabilitation literature.

Abstract Due to advances in cochlear implant technology and the remarkable outcomes often achieved by persons with severe to profound hearing loss, cochlear implant candidacy criteria has expanded since the first children were implanted almost twenty years ago. Evidence of this can be seen in the increased willingness to provide cochlear implants for children with multiple disabilities. Over the last decade, several reports have appeared in the peer-reviewed literature describing cochlear implant outcomes of children with multiple disabilities. This paper will summarize those reports, discuss realistic expectations of implantation for children with multiple disabilities, and describe contemporary management protocols for the otologic, audiologic, and rehabilitative management of children with multiple disabilities.

Cochlear implants are now established as the treatment of choice in the rehabilitation of children with bilateral profound sensori neural hearing impairment. This study objective is to analyze and the development of auditory skills for the cochlear implantation children. This study included 50 children attending the Therapy centre, Tiruchirappalli. Their age ranged below 24 months. All children had bilateral sensori-neural hearing loss since birth. None of the subjects had prior Cochlear implant, but all had tried conventional hearing aid. All subjects were implanted unilateral and bilateral, sequential/simultaneous with CI devices including MED EL and Nucleus. All met the criteria of cochlear implant. All items of the studied auditory skills improved significantly by time. There is significant improvement between 4 to 8 months in the scores of detection, discrimination, identification and comprehension skills. Significant improvement in comprehension is also found between 10 and 11 months interval. PAS score had weak negative correlation with age. Children fitted with cochlear implants showed significant improvement in acquisition of auditory skills over a period of below 1year. The age and the side of the implant are the most significant factors.

Objetivo: Avaliar a qualidade de vida (QV) de pacientes adultos com deficiência auditiva pré e pós-lingual usuários de implante coclear (IC). Método: Os pacientes entrevistados foram adultos implantados de 2004 a 2011 no Departamento de Otorrinolaringologia. Eles responderam ao questionário WHOQoL–BREF e, pela analise dos prontuários, foram identificados como pré ou pós-linguais. Desses pacientes, 17 eram pós-linguais e 8 pré-linguais. Resultados: Verificou-se que, no questionário geral, os participantes pré-linguais apresentaram resultado (escore = 77,4) e os pós-linguais, (escore = 76,3). Os melhores resultados foram os dos domínios físico e psicológico, tanto entre os pacientes pré quanto entre os pós-linguais. Conclusões: Podemos constatar que os pacientes pré-linguais apresentam um resultado pouco melhor que os pós-linguais na pontuação total do questionário, mas a análise dos benefícios do IC nos demais domínios mostrou resultados similares nos dois grupos pesquisados.Palavras chave: Implante coclear, Qualidade de vida, Perfil de impacto da doença, Adulto, Pessoas com deficiência auditivaABSTRACTPurpose: Assess quality of life of adult pre and postlingual hearing impaired patients users of cochlear implants. Method: The interviewed patients were adults who had received their implants between 2004 and 2011 at the Department of Otolaryngology. The questionnaire WHOQoL–BREF was applied and patient records were used to check whether the patient had pre or post-lingual hearing loss. Out of the total, there were 17 post-lingual and 8 pre-lingual patients. Results: We have noticed that pre-lingual patients had the score in the general questionnaire of 77.4, whereas post-lingual subjects reached the score 76.3 in the general questionnaire. The domains that showed good results for pre-lingual subjects were physical (score= 82.4) and psychological (score 78.1), and for post-lingual subjects the score for physical and psychological domains were 82.3 and 77.4, respectively. Conclusion: We have observed that pre-lingual patients presented somewhat worse results than post-lingual subjects in the general score, but when the benefits of cochlear implant are taken into account, this difference between the groups practically disappears.Keywords: Cochlear implantation, Quality of life, Sickness impact profile, Adult, Persons with hearing impairments

<p class="abstract"><strong>Background:</strong> Congenital sensorineural hearing loss (SNHL) is one of the most common birth defects with incidence of approximately 1:1000 live births. Imaging plays an important role in the work up of cochlear implant candidates not only to identify inner ear congenital and acquired abnormalities or cochlear nerve anomalies but also to detect temporal bone abnormalities or variations that may alter surgical approach. Preoperative evaluation of cochleovestibular anatomy is an important component of the cochlear implant evaluation. The objective of the study was high resolution computerized tomography (HRCT) assessment of congenital ear anomalies before cochlear implantation.</p><p class="abstract"><strong>Methods:</strong> This prospective study was conducted in the Department of Radio diagnosis and Imaging, GMC, Srinagar. 24 children in the age group of 1 to 12 years with unidentified causes of bilateral SNHL were subjected to HRCT over a period of 7 months from January to July 2019.  </p><p class="abstract"><strong>Results:</strong> Eighteen patients had normal radiological scans and 6 had congenital anomalies. We had one each case of common cavity, bilateral labrynthine aplasia, incomplete partition type 1, Mondini’s deformity with dilated vestibular duct, Internal auditory canal stenosis and bilateral large vestibular aqueduct. Out of 18 patients without congenital anomaly, two had Korner’s septum and giant jugular bulb which were important for operating surgeon.</p><p><strong>Conclusions:</strong> HRCT temporal bone is superior at identifying the bony labyrinth, including enlarged vestibular aqueduct and caliber of internal auditory canal. HRCT temporal bone should be supplemented by magnetic resonance imaging especially for cochlear nerve assessment. It is the initial imaging modality of choice for assessment of congenital SNHL. </p>
