Objective: To determine audiological and clinical results of cochlear implantation (CI) comparing two populations with single-sided deafness (SSD): post-lingually deaf children between 6 and 12 years of age, and post-lingually deaf adults, in order to evaluate the effect of CI in different age groups.Design: Retrospective case review.Setting: Tertiary clinic.Patients and Method: Twenty-three children and twenty-one adult patients that were candidates for CI with single-side deafness were included. In all cases we evaluate: Speech perception thresholds; disyllabic words test (65 dB SPL) were performed in the modalities S0–SCI–SNH and Auditory Lateralization Test. The Speech, Spatial, and Qualities of Hearing Scale (SSQ) questionnaire was also used. All results were obtained after 12 months of CI activation.Results: In children, the most common etiology was idiopathic sensory-neural hearing loss. They showed positive results in the Auditory Lateralization Test. In the Speech Test, word recognition in noise improved from 2% preoperatively to 61.1% at a mean follow-up of 1 year (S0 condition) in children [test with signal in CI side 60% and signal normal hearing side (plugged) 31%]. The processor was used for >12 h in all cases. With respect to the SSQ questionnaire, parents were more satisfied within the postoperative period than within the preoperative period. For adults, the most common etiology was idiopathic sudden sensorineural hearing loss (SNHL). Positive results in the Auditory Lateralization Test were found. With respect to the Speech Test in quiet conditions: Word recognition in noise improved from 5.7% preoperatively to 71.8% at a mean follow-up of 1 year [test with signal in CI side 68% and signal normal hearing side (plugged) 41%]. The processor was used for >12 h. In the SSQ questionnaire, the post-operative results showed a beneficial effect of the CI. No adverse events were reported during the study period. No differences were found between children and adults in all tests in this study.Conclusions: Cochlear implantation in post-lingually deaf adults and children with SSD can achieve a speech perception outcome comparable with CI in conventional candidates. Improvements in spatial hearing were also observed. Careful patient selection and counseling regarding potential benefits are important to optimize outcomes.

Objective Be able to retrospectively review the complications of pediatric patients undergoing cochlear implantation at a tertiary referral center. Methods IRB permission was obtained. Retrospective analysis of all children who underwent cochlear implantation from January 2001 to December 2005 at a major academic cochlear implantation center. The patients were reviewed for demographic information, type of hearing loss, cochlear implant device, and complications, including implant failure, meningitis, hematomas (intracranial and extracranial), implant extrusion, cerebrospinal fluid leaks, facial palsy, and wound infections. Results A total of 165 patients records were reviewed. 53.5% of the patients were male. The most common device used was the Freedom NucleusTM (60%). The most common etiology of hearing loss was non-syndromic, non-genetic, congenital sensorineural hearing loss (60.6%) All patients had a follow-up of at least 1 year. The most common complication seen was device failure (3.0%), followed by flap infections (2.6%), and immediate postoperative hematomas (1.9%). There was no difference between the kind of device which failed, statistically. There was only one case of Ps. aeruginosa meningitis in a child with a Mondini deformity, who had the implant removed. Conclusions Cochlear implantation in children continues to be reliable and safe, with a low percentage of severe complications, in experienced hands. The patients should have lifetime follow-up.

Lost To Follow Up

Intralabyrinthine schwannoma (ILS) is a rare benign tumor of the inner ear potentially causing unilateral sensorineural hearing loss and vertigo. This study evaluated the outcome of one surgical session comprising microsurgical ILS resection and cochlear implantation in terms of surgical feasibility, complications, and auditory outcome. Ten clinically and histologically confirmed ILS patients included in this study (three women and seven men; mean age 56.4 ± 8.6) underwent surgery between July 2015 and February 2020. Eight patients had intracochlear tumor location; the remaining two had vestibulocochlear and intravestibular ILS. One of the three following methods was used for tumor removal: an extended cochleostomy, subtotal cochleoectomy, or a translabyrinthine approach. Although negligible improvement was observed in two of the patients, two patients were lost to follow-up, and one opted out from using CI, the speech perception of the five remaining ILS patients improved as per the Freiburg Monosyllable Test (FMT) from 0% before surgery to 45– 50% after the implantation. Our study supports the presented surgical approach’s feasibility and safety, enabling tumor removal and hearing restoration shortly after surgery.

Speech Performance

<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.

Discrimination Methods

Background: The proximity of the electrode to the modiolar wall may be of interest to investigate the effect of pitch discrimination. This research establishes the relation between these factors and whether perimodiolar positions may provide benefits regarding improved electrode discrimination. Methods: A prospective randomized study including 24 post-lingual deaf adults was performed. A psychoacoustic study was done by using a psychoacoustic research platform. Radiological study, and a cone-beam computed tomography was used to assess post cochlear implantation electrodes’ position. Trans-impedance matrix (TIM) analysis was performed after cochlear implant insertion in all cases, and pupillometry test was also performed. Results: 12 patients received a slim perimodiolar electrode array, and 12 patients received a straight electrode array. Although all the patients showed similar speech test results after 12 months follow-up, those implanted with a perimodiolar electrode obtained better scores in electrode discrimination test and pupillometry test, and showed more homogenous TIM patterns. Conclusions: The better positioning of the electrode array seams to provide a better hearing resolution and less listening effort trans-impedance matrix seems to be a useful tool to analyze positioning of the perimodiolar array.

Monosyllabic Word

Background: Children with steeply sloping sensorineural hearing loss (SNHL) lack access to critical high-frequency cues despite the use of advanced hearing aid technology. In addition, their auditory-only aided speech perception abilities often meet Food and Drug Administration criteria for cochlear implantation. Purpose: The objective of this study was to describe hearing preservation and speech perception outcomes in a group of young children with steeply sloping SNHL who received a cochlear implant (CI). Research Design: Retrospective case series. Study Sample: Eight children with steeply sloping postlingual progressive SNHL who received a unilateral traditional CI at Seattle Children’s Hospital between 2009 and 2013 and had follow-up data available up to 24 mo postimplant were included. Data Collection and Analysis: A retrospective chart review was completed. Medical records were reviewed for demographic information, preoperative and postoperative behavioral hearing thresholds, and speech perception scores. Paired t tests were used to analyze speech perception data. Hearing preservation results are reported. Results: Rapid improvement of speech perception scores was observed within the first month postimplant for all participants. Mean monosyllabic word scores were 76% and mean phoneme scores were 86.7% at 1-mo postactivation compared to mean preimplant scores of 19.5% and 31.0%, respectively. Hearing preservation was observed in five participants out to 24-mo postactivation. Two participants lost hearing in both the implanted and unimplanted ear, and received a sequential bilateral CI in the other ear after progression of the hearing loss. One participant had a total loss of hearing in only the implanted ear. Results reported in this article are from the ear implanted first. Bilateral outcomes are not reported. Conclusions: CIs provided benefit for children with steeply sloping bilateral hearing loss for whom hearing aids did not provide adequate auditory access. In our cohort, significant improvements in speech understanding occurred rapidly postactivation. Preservation of residual hearing in children with a traditional CI electrode is possible.

Radical Cavity

Patients with chronic otitis media (COM) may have profound sensorineural hearing loss either due to the disease process or secondary to a surgical procedure. Some patients who are candidates for cochlear implantation may have COM coincidentally. The patients in this group need special attention when cochlear implantation is applied. The aim of this study is to evaluate the potential risks and complications in patients with COM.Cochlear implantation was performed in six patients with COM or an infected radical cavity and profound hearing loss. Five of them underwent a two-stage operation, and one had a single-stage operation. Cochlear implantation was performed in all patients without complications. The follow-up period was uneventful.Although such patients have some potential risks, when certain surgical rules are followed very strictly cochlear implantation can be successfully performed in patients with COM.
