Speech Auditory Brainstem Responses in Adult Hearing Aid Users: Effects of Aiding and Background Noise, and Prediction of Behavioral Measures.

Evaluation of patients who are unable to provide behavioral responses on standard clinical measures is challenging due to the lack of standard objective (non-behavioral) clinical audiological measures that assess the outcome of an intervention (e.g., hearing aids).

Speech-ABRs in cochlear implant recipients: feasibility study.

The aim of this study was to assess the feasibility of recording speech-ABRs from cochlear implant (CI) recipients, and to remove the artefact using a clinically applicable single-channel approach. Speech-ABRs were recorded to a 40 ms [da] presented loudspeaker using a two-channel electrode montage. Additionally, artefacts were recorded using an artificial-head incorporating a MED-EL CI with stimulation parameters as similar as possible to those of three MED-EL participants.

Speech Auditory Brainstem Responses: Effects of Background, Stimulus Duration, Consonant-Vowel, and Number of Epochs.

Objectives: The aims of this study were to systematically explore the effects of stimulus duration, background (quiet versus noise), and three consonant-vowels on speech-auditory brainstem responses (ABRs). Additionally, the minimum number of epochs required to record speech-ABRs with clearly identifiable waveform components was assessed. The purpose was to evaluate whether shorter duration stimuli could be reliably used to record speech-ABRs both in quiet and in background noise to the three consonant-vowels, as opposed to longer duration stimuli that are commonly used in the literature.

Subjective outcomes of auditory brainstem implantation.

Aim: To assess the long-term subjective benefits of auditory brainstem implants (ABIs) and investigate the extent to which ABI users perceive it to be a useful device.

Methods: Using the Manchester database, all 31 living patients registered as ABI users were identified and sent the ABI performance questionnaire. Data regarding daily duration of use, auditory fatigue, ability to differentiate between speech and environmental sounds, and subjective usefulness of the ABI in different listening conditions were collected.

Straight versus modiolar hugging electrodes: does one perform better than the other?

Objective: To determine differences in speech perception outcomes for patients who received a CI422 and a Contour cochlear implant.

Study Design: Retrospective case review.

Setting: Tertiary referral center.

Ipsilateral cochlear implantation after cochlear nerve preserving vestibular schwannoma surgery in patients with neurofibromatosis type 2.

Objective: To investigate the outcomes from ipsilateral simultaneous or sequential cochlear implantation in patients with neurofibromatosis type 2 (NF2) after vestibular schwannoma removal with cochlear nerve preservation.

Study Design: Retrospective case series.

Setting: Single tertiary referral NF2 center.

Feasibility of cochlear implantation in Mucopolysaccharidosis.

Unlabelled: Mucopolysaccharidoses (MPS) are a group of rare inherited metabolic disorders resulting from deficiencies of particular enzymes involved in the breakdown of glycosaminoglycans. Amongst the manifestations of MPS within the head and neck patients may develop conductive, mixed or sensorineural hearing loss.

Objective: The main objective of this paper is to describe the management of profound sensorineural hearing loss in children with Mucopolysaccaridosis.

Cochlear implantation in patients deafened by ototoxic drugs.

Objective: To investigate the outcome of cochlear implantation (CI) in patients deafened by ototoxic drugs and to compare this, with the outcome of CI in sudden sensorineural hearing loss (SSNHL) with a similar duration of deafness.

Methods: The Manchester Auditory Implant Centre database was reviewed to identify patients who were implanted to rehabilitate profound sensorineural hearing loss resulting from treatment with ototoxic agents and patients with SSNHL group. A retrospective case note review of selected patients was carried out.

Hearing preservation via a cochleostomy approach and deep insertion of a standard length cochlear implant electrode.

Objective: The suggestion that the depth of insertion of the electrode into the cochlea is critical to hearing preservation has led to the development of a generation of short electrodes designed to minimize intracochlear trauma and avoid contact with the apical region of the cochlea. This study aims to describe our experience of hearing preservation surgery using a deeply inserted standard length electrode array covering the region of residual hearing.

Study Design: A retrospective case note review was performed identifying cases of attempted hearing preservation using standard length electrodes.

Cochlear implantation in children with cerebral palsy.

Objective: Few studies have looked at the outcomes of children with complex needs following cochlear implantation. Increasing evidence supports the case for implantation in these children. To date there is very little evidence available evaluating the role of cochlear implantation in children with cerebral palsy.

Cochlear implantation after bacterial meningitis in children: outcomes in ossified and nonossified cochleas.

Objective: To investigate the outcome of cochlear implantation in children with postmeningitic deafness and to compare the outcomes in ossified and nonossified cochleas.

Study Design: A retrospective case note review of children with postmeningitic deafness requiring cochlear implantation.

Setting: Manchester Auditory Implant Centre--a tertiary referral center.
