Emotional recognition of dynamic facial expressions before and after cochlear implantation in adults with progressive deafness.

Visual processing has been extensively explored in deaf subjects in the context of verbal communication, through the assessment of speech reading and sign language abilities. However, little is known about visual emotional processing in adult progressive deafness, and after cochlear implantation. The goal of our study was thus to assess the influence of acquired post-lingual progressive deafness on the recognition of dynamic facial emotions that were selected to express canonical fear, happiness, sadness, and anger.

Cognitive Evaluation of Cochlear Implanted Adults Using CODEX and MoCA Screening Tests.

Objective: The relationship between hearing loss and cognitive function has already been established. The objective of our study was to determine whether the two short cognitive tests, COgnitive Disorders EXamination (CODEX) and Montreal Cognitive Assessment (MoCA), could be used in daily clinical practice to detect cognitive impairment, and its changes after cochlear implantation.

Patients: Eighteen patients with severe to profound postlingual progressive hearing loss (mean age ± SEM: 64 ± 3.

Benefit of the UltraZoom beamforming technology in noise in cochlear implant users.

The objectives of the study were to demonstrate the audiological and subjective benefits of the adaptive UltraZoom beamforming technology available in the Naída CI Q70 sound processor, in cochlear-implanted adults upgraded from a previous generation sound processor. Thirty-four adults aged between 21 and 89 years (mean 53 ± 19) were prospectively included. Nine subjects were unilaterally implanted, 11 bilaterally and 14 were bimodal users.

Judgment of musical emotions after cochlear implantation in adults with progressive deafness.

While cochlear implantation is rather successful in restoring speech comprehension in quiet environments (Nimmons et al., 2008), other auditory tasks, such as music perception, can remain challenging for implant users. Here, we tested how patients who had received a cochlear implant (CI) after post-lingual progressive deafness perceive emotions in music.

Brain voice processing with bilateral cochlear implants: a positron emission tomography study.

Most cochlear implantations are unilateral. To explore the benefits of a binaural cochlear implant, we used water-labelled oxygen-15 positron emission tomography. Relative cerebral blood flow was measured in a binaural implant group (n = 11), while the subjects were passively listening to human voice sounds, environmental sounds non-voice or silence.

Is electrode-modiolus distance a prognostic factor for hearing performances after cochlear implant surgery?

The aim of this study was to evaluate electrode array position in relation to cochlear anatomy and its influence on hearing performance in cochlear implantees. Twenty-two patients (25 ears) with Med-El cochlear implants were included in this retrospective study. A negative correlation was observed between electrode-modiolus distance (EMD) at the cochlear base and monosyllabic word discrimination 6 months after implantation.

New cochlear implant technologies improve performance in post-meningitic deaf patients.

The objective of the study was to compare the performance of cochlear implantation between post-meningitic and non-meningitic patients, and to evaluate the impact on hearing outcome of technical advances in cochlear implant technology. Retrospective chart review was used as the study design. Twenty adults with post-meningitic profound hearing loss receiving unilateral or bilateral cochlear implants between 1990 and 2008 were tested.

Processing of voices in deafness rehabilitation by auditory brainstem implant.

The superior temporal sulcus (STS) is specifically involved in processing the human voice. Profound acquired deafness by post-meningitis ossified cochlea and by bilateral vestibular schwannoma in neurofibromatosis type 2 patients are two indications for auditory brainstem implantation (ABI). In order to objectively measure the cortical voice processing of a group of ABI patients, we studied the activation of the human temporal voice areas (TVA) by PET H(2)(15)O, performed in a group of implanted deaf adults (n=7) with more than two years of auditory brainstem implant experience, with an intelligibility score average of 17%+/-17 [mean+/-SD].

Auditory brainstem implant in neurofibromatosis type 2 and non-neurofibromatosis type 2 patients.

Objective: To evaluate the auditory brainstem implant (ABI) performances in neurofibromatosis type 2 (NF2) and non-NF2 patients.

Study Design: Retrospective cohort study.

Setting: Tertiary referral center.

Speech performance and sound localization in a complex noisy environment in bilaterally implanted adult patients.

Objective: To evaluate speech performance, in quiet and noise, and localization ability in adult patients who had undergone bilateral and simultaneous implantation.

Study Design: Prospective multi-center study.

Methods: Twenty-seven adult patients with profound or total hearing loss were bilaterally implanted in a single-stage procedure, and simultaneously activated (Med-El, Combi 40/40+).

Cochlear implant benefits in deafness rehabilitation: PET study of temporal voice activations.

Unlabelled: Cochlear implants may improve the medical and social prognosis of profound deafness. Nevertheless, some patients have experienced poor results without any clear explanations. One correlate may be an alteration in cortical voice processing.
