Organización de un programa de implantes cocleares
A cochlear implant (CI) programme brings together a number of professionals who,
during the stages of selection, surgery, programming, rehabilitation and monitoring, develop a
series of tasks aimed at promoting comprehensive attention to the implanted patient.
The aim of this paper was to describe in detail the tasks in each of the phases described in a
programme of CI, materials and necessary equipment and the role of the professionals involved.
It also raised a number of recommendations on how to develop a CI programme gradually to
facilitate the progression from the simplest to the mos
Tipos de implantes activos de oÃdo medio
Active middle ear implants are classified as piezoelectric implants,
which use the properties of piezoelectric materials.
There are two types of piezoelectric implants: monomorphic
and dimorphic; electromagnetic transduction uses a magnet,
usually a rare earth magnet (e.g. samarium cobalt) and an
energizing coil. This magnetic field causes the magnet to vibrate,
which in turn, through the tympanic-ossicular chain,
causes movement of the cochlear fluids. Electromechanical
transduction is a variation of electromagnetic transduction
Hearing Impairment and Quality of Life in Adults with Asymmetric Hearing Loss: Benefits of Bimodal Stimulation
Objectives: Bimodal stimulation for asymmetric hearing loss is an emerging treatment with proven audiometric outcomes. Our objectives are to assess the changes of the hearing impairment and the quality of life of patients treated with this type of stimulation, when compared to a unilateral Cochlear Implant (CI) stimulated condition.
Materials and methods: 31 patients with asymmetric hearing loss (Group 1) were recruited for the study. They were divided into three groups, based on their hearing loss in the ear treated with the hearing aid: Group 1A (Pure Tone Audiometry (PTA) between 41 and 70 decibels (dB)); Group 1B, (PTA between 71 and 80 dB) and Group 1C (PTA between 81 and 90 dB). 30 patients had profound, bilateral hearing loss. Then, users of a unilateral cochlear implant were recruited for the control group. Their hearing impairment and quality of life were analyzed with questionnaires Abbreviated Profile of Hearing Aid Benefit (APHAB), Speech, Spatial and Qualities of Hearing Scale (SSQ) and the Health Utilities Index (HUI). They were followed up for at least 2 years.
Results: The group with the asymmetric hearing loss obtains a statistically significant clinical improvement in the APHAB under category "with hearing aid" compared to "without hearing aid". The group with the asymmetric hearing loss benefits more across basically all variables compared with the control group in the SSQ. Group 1A obtains the best outcome of the sample in the HUI.
Conclusion: Bimodal stimulation and better hearing in the ear treated with the hearing aid reduce hearing impairment and improve the quality of life
Treatment for hearing loss among the elderly: auditory outcomes and impact on quality of life
The study aim was to determine the benefit of cochlear im-
plantation and hearing aids in older adults diagnosed with
hearing loss and to evaluate the index of depression, anxiety
and quality of life after such treatments. A retrospective co-
hort comprised 117 patients older than 65 years and diag-
nosed with moderate to profound hearing loss who were
included and classified into 2 groups (treated vs. non-treat-
ed). A battery of tests including auditory (pure-tone average,
disyllabic words in quiet at 65 dB SPL) and findings from a
series of questions relevant to quality of life were compared
between both groups. Auditory outcomes for disyllabic
words were 58.21% for the cochlear implant-treated group
and 82.8% for the hearing aid-treated group. There was a
positive effect on anxiety, depression, health status and
quality of life in the cochlear implant group versus the pro-
found hearing loss control group. We conclude that older
adults with moderate to profound hearing loss gain benefit from hearing aids or cochlear implants not only in terms of
improved hearing function, but also in terms of positive ef-
fects on anxiety, depression, health status and quality of life
GuÃa clÃnica para la indicación de implantes cocleares en la Comunidad Foral de Navarra
La colocación de un implante coclear es una medida útil para paliar la hipoacusia neurosensorial de grado severo-profundo en aquellos casos en los que el beneficio del audÃfono es escaso. Desde su inicio hace 30 años los resultados auditivos han mejorado gracias a los progresivas mejoras que se han adoptado en distintos ámbitos: su diseño, estrategia, técnica quirúrgica... Dados los buenos resultados en este periodo, las indicaciones también han variado. El objetivo de este trabajo es revisar los criterios establecidos y emergentes de indicación de implante coclear, estableciendo de manera consensuada, entre los centros sanitarios de la Comunidad Foral de Navarra, unos criterios actualizados para la indicación del mismo en dicha área territorial, de forma que pueden servir de referencia en situaciones clÃnicas diferenciadas.Cochlear implants are indicated in severe to profound hearing loss with no benefit with hearing aids.
Since the beginning of cochlear implants 30 years ago, auditory outcomes have been improving due to changes introduced in different areas: electrode design, strategy, surgical technique... Given good results within this period of time, cochlear implant indication has varied too. The aim of this paper is to show an update on indication criteria for cochlear implantation in Navarre, for application in daily practice. The indications are established by consensus amongst the hospitals of the region
The Listening Network and Cochlear Implant Benefits in Hearing-Impaired Adults
Older adults with mild or no hearing loss make more errors and expend more effort listening to speech. Cochlear implants (CI) restore hearing to deaf patients but with limited fidelity. We hypothesized that patient-reported hearing and health-related quality of life in CI patients may similarly vary according to age. Speech Spatial Qualities (SSQ) of hearing scale and Health Utilities Index Mark III (HUI) questionnaires were administered to 543 unilaterally implanted adults across Europe, South Africa, and South America. Data were acquired before surgery and at 1, 2, and 3 years post-surgery. Data were analyzed using linear mixed models with visit, age group (18–34, 35–44, 45–54, 55–64, and 65+), and side of implant as main factors and adjusted for other covariates. Tinnitus and dizziness prevalence did not vary with age, but older groups had more preoperative hearing. Preoperatively and postoperatively, SSQ scores were significantly higher (¿0.75–0.82) for those aged <45 compared with those 55+. However, gains in SSQ scores were equivalent across age groups, although postoperative SSQ scores were higher in right-ear implanted subjects. All age groups benefited equally in terms of HUI gain (0.18), with no decrease in scores with age. Overall, younger adults appeared to cope better with a degraded hearing before and after CI, leading to better subjective hearing performance.

Vestibulo-cochlear fuction after cochlear implantation in patients with Meniere's disease
OBJECTIVES: To measure the auditory (pure tone audiometry and word recognition scores) and vestibular (video head impulse test and vestibular myogenic potentials) outcomes in patients diagnosed with Meniere’s disease (MD) who underwent cochlear implantation.
MATERIAL AND METHODS: This prospective study included 23 cochlear implant users with MD and 29 patients diagnosed with far-advanced otosclerosis (the control group).
RESULTS: The preoperative mean pure tone average thresholds were 99 and 122.5 dB for the Meniere’s and control groups, respectively. Word recognition scores after cochlear implant yielded a median of 80% and 72% for the Meniere’s and control groups, respectively. Semicircular canal gain was not observed to vary post implantation (mean variation for lateral, posterior, and anterior plane was 0, 0.03, and 0, respectively). The mean ocular and
cervical myogenic potentials asymmetry varied as 9.65% and 18.39%, respectively.
CONCLUSIONS: The auditory performance improved in patients with MD similar to the general cochlear implant population. No major dysfunction of otolithic or semicircular canal function was demonstrated after the implantation surger
