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...

OBJECTIVE: HIV-infected patients have an increased risk of developing sensorineural hearing loss. Cochlear implantation can be a mean of rehabilitating such patients. METHODS: A 36-year-old HIV-infected male with bilateral profound sensorineural hearing loss underwent cochlear implantation after exclusion of medical and radiological contraindications. The patient was followed up for 2 years to assess the audiological outcome. RESULTS: After a follow up of 2 years, the patient has attained good functional results not experienced any complications...

OBJECTIVES: To describe the frequency and characteristics of complications of cochlear implant (CI) surgery at Edgardo Rebagliati Martins Hospital of social security in Lima-Peru between 2006 and 2015. METHODS: A retrospective descriptive study of patients that underwent CI surgery between August 2006 and December 2015. RESULTS: Among the 107 patients with CIs, the overall proportion of complications was 18.7% (20/107): 14.9% (16/107) of minor complications, and 3...

In neurofibromatosis type 2 (NF2) bilateral vestibular schwannomas (VS) or their treatment usually results in bilateral hearing loss. Cochlear implantation (CI) was traditionally not used in these patients due to concern that retrocochlear disease would render the implant ineffective. This paper describes the auditory outcomes of CI in 13 patients with NF2 and includes patients with untreated VS and patients undergoing VS removal with cochlear nerve preservation. The non-user rate was 7.7%. Of the active users, median CUNY score was 98%, median BKB score in quiet was 90% and median BKB score in noise was 68%...

OBJECTIVE: To assess the compliance with cochlear implantation (CI) in children subsequently diagnosed with autism spectrum disorder (ASD). METHODS: This was a retrospective case review and survey performed at a tertiary referral centre. Children meeting the criteria for CI who were implanted between 1989 and 2015 and who subsequently received a diagnosis of ASD were included. The primary outcome measure was to assess compliance with CI in children subsequently diagnosed with ASD...

OBJECTIVE: Cochlear implantation is routinely performed under general anaesthesia in most centres in the world. There have been reports of this surgery being performed under local anaesthesia and sedation for unilateral cochlear implantation. Our case study reports the first bilateral cochlear implantation carried out under local anaesthesia with sedation. This paper outlines the protocol used and discusses the challenges and advantages of the procedure being performed under local anaesthesia...

OBJECTIVES: Cochlear implantation is becoming widely used outside the tertiary research centers for treatment of unilateral deafness (UD). No consensus exists, however, on the most suitable assessment/evaluation protocols for this group of adult patients. This paper aims to review the assessment and evaluation protocols used by various research groups and to propose a protocol for the use in the clinical setting. METHODS: The PubMed, Embase, and Cochrane Library databases were searched with the keywords 'cochlear', 'implant', 'single-sided', 'deafness', 'adults', 'unilateral', and 'deafness'...

OBJECTIVE AND IMPORTANCE: In children with X-linked deafness, cochlear malformations challenge the implant surgeon to avoid electrode insertion into the internal auditory meatus and prevent a continuous cerebrospinal fluid (CSF) leak. We describe our experience of cochlear implantation (CI) in two children with profound hearing loss secondary to X-linked deafness, highlighting safer operative techniques to avoid potential complications. CLINICAL PRESENTATION: Descriptive cases of two children with X-linked deafness (patient 1 and patient 2) undergoing CI...

OBJECTIVE: To examine the auditory benefit of cochlear implants (CI) in patients with single-sided deafness (SSD). MATERIAL AND METHODS: Twenty patients with a normal pure tone audiogram (n = 8) or moderate hearing loss (n = 12) in one ear and a CI system MED-EL SONATA/CONCERTO + OPUS2 (n = 12), COCHLEAR CI24RE(ST) + CP810 (n = 7) and Advanced Bionics HiRes90 K + Harmony (n = 1) in the contralateral ear and with at least 6 months of CI experience were tested with respect to directional hearing, speech perception in noise, binaural loudness matching, and binaural pitch matching...

OBJECTIVE: This case report aims to emphasize the importance of preoperative computed tomography to evaluate the anatomy of the facial recess (FR) in order to prevent complications during cochlear implantation (CI) and to discuss alternative surgical approaches for the management of a narrow FR. Failure to notice this anomaly may result in facial nerve (FN) injury or inability to complete CI. CASE PRESENTATION: A 50-year-old female with bilateral sensorineural hearing loss presented for CI...

OBJECTIVES: The study surveyed practising cochlear implant (CI) audiologists with the aim of: (1) characterizing UK clinical practice around the management and fitting of a contralateral hearing aid (HA) in adult unilateral CI users ('bimodal aiding'); (2) identifying factors that may limit the provision of bimodal aiding; and (3) ascertaining the views of audiologists on bimodal aiding. METHODS: An online survey was distributed to audiologists working at the 20 centres providing implantation services to adults in the UK...

OBJECTIVES: To determine and evaluate the time clinics needed to complete the sub-processes involved in the first-fitting and follow-up fitting of people with a cochlear implant. METHODS: Eight HEARRING clinics completed a questionnaire recording how long it took to complete the sub-processes involved in first-fitting and follow-up fitting cochlear implant recipients. The mean times of clinics and procedures were then compared. RESULTS: Questionnaires on 77 patients were completed...

OBJECTIVES: To evaluate the speech discrimination performance of elderly post-lingually deafened cochlear implant (CI) users and the stability of performance over time relative to a control group of younger CI users. METHODS: The study group consisted of 20 native Dutch speaking, post-lingually deafened CI users, aged 70 or older at the time of implantation. Controls were patients aged 40-60 years at implantation and included according to the same inclusion criteria (except age)...

OBJECTIVES: The aim of this study was to analyse the tissue surrounding the University of Melbourne's (UOMs) multi-channel cochlear implant electrode array and cochlear limited replacements, after long-term implantations. In particular, it aimed to identify the particulate material in the fibrous tissue capsule of the arrays implanted in 1978, 1983, and 1998, by using the Australian Synchrotron for X-ray fluorescence microscopy (XFM) to reveal the characteristic spectrum of metal, in particular platinum...

OBJECTIVE: The aim of this study was to analyze vestibular function in cochlear implant (CI) patients for iatrogenic damage to vestibular function. METHODS: Prospective clinical study. Tertiary care audiological center. Twenty-five subjects receiving surgery for cochlear implantation during 2012 and 2013 were analyzed. Both vestibulo-ocular and vestibulo-spinal responses before and 2 months after CI surgery were evaluated using several tests: analysis of spontaneous nystagmus, head shaking test (HST), and head impulse test recorded by videooculography; caloric stimulation at 44° and 30° in both ears; cervical evoked myogenic potentials and static stabilometry...
