DISCRIMINATION DES TRAITS PHONÉTIQUES AU TRAVERS DES IMPLANTS COCHLÉAIRES

Nous présentons les résultats de discrimination de 11 patients adultes implantés avec différents systèmes mono et multicanaux. Par comparaison avec les prédictions faites à partir des études sur le codage de la parole dans le nerf auditif par indices neuronaux (1). Nous montrons que si les traits phonétiques de voisement et de continuité sont bien discriminés quels que soient les types d'implants et que la discrimination du trait de nasalité est améliorée dans certains cas, les autres traits phonétiques de tonalité et de compacité ne sont pas catégorisés, même au travers des implants multicanaux.The authors present the results of phonetic discrimination in 11 adult patients implanted with variouss mono and multichannel systems. By comparison with predictions based upon studies of the coding of speech in the auditory nerve (1), it is shown that while the phonetic feature of voicing and continuity are well discriminated regardless of the type of implant and that the discrimination of the feature of nasality is improved in certain cases, the other phonetic feature of tonality and compactness are not categorized, even via multichannel implants

French Society of ENT (SFORL) guidelines. Indications for cochlear implantation in adults

International audienceThe authors present the guidelines of the French Society of ENT and Head and Neck Surgery (SFORL) regarding indications for cochlear implantation in adults. After a literature review by a multidisciplinary workgroup, guidelines were drawn up based on retrieved articles and group-members' experience, then read over by an independent reading group to edit the final version. Guidelines were graded A, B, C or "expert opinion" according to decreasing level of evidence. There is no upper age limit to cochlear implantation in the absence of proven dementia and if autonomy is at least partial. Bilateral implantation may be proposed if unilateral implantation fails to provide sufficiently good spatial localization, speech perception in noise and quality of life, and should be preceded by binaural hearing assessment. Rehabilitation by acoustic and electrical stimulation may be proposed when low-frequency hearing persists. Quality of life should be assessed before and after implantation
