OBJECTIVES: (1) To describe auditory performance and subjective benefits in adults with congenital or prelingual deafness who received a cochlear implant (CI) during adolescence or adulthood, and (2) to examine the benefits as experienced by these CI users. METHODS: Twenty-one adults aged 23-65 years participated in the study. All had a congenital or prelingual deafness (onset before age 3). They received a CI between the age of 16 and 61 years (mean age: 31). Speech recognition scores before and after implantation were computed and a questionnaire on subjective benefits (French adaptation of the Adult Cochlear Implant Questionnaire, designed by Zwolan and collaborators (1996, Self-report of CI use and satisfaction by prelingually deafened adults...

OBJECTIVE: To illustrate our experience when managing a complex patient with potentially life-threatening bilateral otological disease facing multisensory compromise including complete loss of audiovestibular function and visual disturbance Clinical presentation: A 67 year old lady, presented with a large left vestibular schwannoma and extensive right cholesteatoma encircling the otic capsule. She underwent translabyrinthine resection of the vestibular schwannoma, resulting in profound sensorineural hearing loss, vestibular hypofunction and corneal scarring following an initial temporary facial palsy...

OBJECTIVES: To evaluate the validity of the Digit Triplet Test (DTT) in a simulated home environment for measuring speech recognition in adults with cochlear implants by comparing the result to clinic speech perception tests. To evaluate the acceptability of the DTT in adults using cochlear implants. METHODS: A prospective single-centre study with the following outcomes: • DTT Speech Reception Threshold • Clinic speech perception tests (BKB sentences in quiet and noise, City University of New York sentences with lip-reading) • A satisfaction questionnaire to assess patient perception of the DTT Sixteen people using cochlear implants aged from 43 to 83 years took part...

OBJECTIVES: To report our institutional experience of the management of patients with enlarged vestibular aqueduct (EVA) and compare it to the literature. METHODS: We carried out a retrospective review of patients' records from 1993 to 2015. The age, sex, associated malformations, relevant past medical history, genetic screening results, possible surgical incident, implant model and duration of follow- up, outcome in terms of Categories of Auditory Performance (CAP scores), and integration or resuming mainstream school or work were recorded...

OBJECTIVE: To report the preliminary outcomes of auditory brainstem implantation (ABI) under a compassionate use protocol for two ABI devices that are not approved by the US Food and Drug Administration. METHODS: A retrospective review was performed of neurofibromatosis type 2 (NF2) patients who underwent microsurgery for vestibular schwannoma (VS) and placement of either the Cochlear ABI541 or Med-El Synchrony ABIs. Peri-operative and device- related complications were reviewed...

OBJECTIVES: This fourteen-centre project used professional rating scales and parent questionnaires to assess longitudinal outcomes in a large non-selected population of children receiving simultaneous and sequential bilateral cochlear implants. METHODS: This was an observational non-randomized service evaluation.

INTRODUCTION: The microgrinding technique is used to study cochlear implant electrode positioning and cochlear trauma. It may be argued that this technique might cause damage to inner cochlear structures even without a cochlear implant insertion and thus it should not be recommended. Most papers do not explain how microgrinding is performed, referring to older papers for its description. Properly describing the technique and re-evaluating its safety may reassure researchers of their findings when studying trauma after cochlear implant insertion...

OBJECTIVES: Teenage cochlear implant users' perceptions of deafness, surgery, fitting of the device and life as a cochlear implant wearer were explored in order to gain a more comprehensive understanding of teenagers' experiences of living with the device. METHODS: Semi-structured in-depth interviews were undertaken and analysed using thematic analysis. Ten teenagers aged 14-16 years with at least one cochlear implant were interviewed. RESULTS: Seven teenagers experienced great pre-operative anxiety and two reported significant post-operative pain...

One of the many parameters that can affect cochlear implant (CI) users' performance is the site of presentation of electrical stimulation, from the CI, to the auditory nerve. Evoked compound action potential (ECAP) measurements are commonly used to verify nerve function by stimulating one electrode contact in the cochlea and recording the resulting action potentials on the other contacts of the electrode array. The present study aimed to determine if the ECAP amplitude differs between the apical, middle, and basal region of the cochlea, if double peak potentials were more likely in the apex than the basal region of the cochlea, and if there were differences in the ECAP threshold and recovery function across the cochlea...

OBJECTIVES: The diagnosis of non-organic hearing loss (NOHL) is a difficult but important issue during the assessment process for cochlear implantation (CI). We aim to identify the key factors in identifying patients with NOHL during CI assessment and present our local screening protocol for NOHL. METHODS: A retrospective review of patients referred to the Yorkshire Auditory Implant Service (YAIS) between 2003 and 2015 who were subsequently diagnosed with NOHL during the assessment...

INTRODUCTION: With the aim of preventing migration of cochlear implantation electrodes in the postoperative course, an electrode fixation clip has been developed. It is characterized by two clips of double U-geometry. The bone fixation clip will be clamped on the bony incus bridge, and the electrode fixation clip is clamped to the electrode lead. Although made of titanium, the detectability in radiologic imaging appears limited. MATERIALS AND METHODS: Six patients, who received a cochlear implant between August 2014 and March 2015, were retrospectively analyzed for the detectability of the Med-El Electrode Fixation Clip in postoperative cone beam CT scans...

OBJECTIVE: Assess whether differences in speech perception are observed after exclusive listening experience with high-definition continuous interleaved sampling (HDCIS) versus fine structure processing (FSP) coding strategies. METHODS: Subjects were randomly assigned at initial activation of the external speech processor to receive the HDCIS or FSP coding strategy. Frequency filter assignments were consistent across subjects. The speech perception test battery included CNC words in quiet, HINT sentences in quiet and steady noise (+10 dB SNR), AzBio sentences in quiet and a 10-talker babble (+10 dB SNR), and BKB-SIN...
