Se ha empezado a investigar los efectos de la implantación a nivel del desarrollo social y emocional del niño. El objetivo es examinar los resultados de la salud relacionados con la calidad de vida en niños sordos implantados cocleares de entre 11 y 12 años de edad y sus padres. Método: Estudio observacional, descriptivo transversal en 24 niños prelocutivos implantados unilaterales o bilaterales sucesivos de 11 y 12 años de edad y sus padres. Utilizando el cuestionario de calidad de vida pediátrica PedsQL™ (Versión 4.0, español para España), para medir la salud relacionados con la calidad de vida, completado de forma independiente por niños y padres respectivamente. Resultados: Mediante la T-Student los resultados de niños y padres en las diferentes escalas evaluadas observamos que en las escalas de funcionamiento emocional y académica es donde se ...

Therefore, the focus in this field of vestibular research shifted to electrical vestibular stimulation (EVS) and the development of a system capable of artificially restoring the vestibular function. Key Message: Currently, three approaches are being investigated: vestibular co-stimulation with a cochlear implant (CI), EVS with a vestibular implant (VI), and galvanic vestibular stimulation (GVS). All three applications show promising results but due to conceptual differences and the experimental state, a consensus on which application is the most ideal for which type of patient is still missing. Summary: Vestibular co-stimulation with a CI is based on “spread of excitation,” which is a phenomenon that occurs when the currents from the CI spread to the surrounding structures and stimulate them. It has been shown th...

An observational retrospective study was conducted on 26 individuals (17 male and 9 female) older than 60, all implanted in our unit between 1 January 1999 and 31 January 2009. And 10 patients (5 male and 5 female) aged between 40 and 60 were the control group. A full postoperative audiological evaluation was completed. Sociodemographic characteristics and history of hearing loss were collected. To evaluate QoL benefits, the Glasgow Benefit Inventory test and the Specific Questionnaire were filled in. Patients in the test and control groups had similar preoperative speech recognition levels. Preoperative audiometric thresholds were significantly worse in patients from 40 to 60 years of age although they scored better in speech recognition after implantation. Patients experienced significant improvement in their QoL in all areas, especially in general health, while they experienced a smaller improvement in social interaction. Age, duration of deafness, and years wearing the processor were statistically related to QoL regardless of audiometric benefit. Unilateral CI users and patients without tinnitus obtain better QoL although no statistical relation was found. Cochlear implantation improves QoL of patients over 60 by the mere fact of having been implanted, regardless of poorer audiological benefits. Older patients, with long-term deafness experience a greater improvement in QoL after implantation. The results of this study should aid other centers when counseling patients on the expected, daily functional benefits of cochlear implantation.

We present the results according to the surgical approach applied in each case. This retrospective study presents the findings in 17 patients with diagnosis of glomus jugulare of the temporal bone, who were observed and treated in our department over a 5-year period (1999 to 2004). We performed a general otolaryngology exam, systemic evaluation and radiological exam. Surgical treatment was performed in 16 cases out of 17. In 1 case treatment with stereotaxic surgery was performed. The surgical approaches were: retroauricular transcanal approach, radical or modified mastoidectomy through facial recess, and infratemporal fossa approach. Pre-operative embolization was used in 11 of our cases. In all cases the diagnosis of glomus tumour was confirmed. The most frequent post-operative complications found were: transitory paralysis of the facial nerve, sensorineural hearing loss, imbalance, paralysis of the IXth and XIth cranial nerves, and salivary fistula. No recurrences were found after 8 years of follow-up. One case of persistence was found in the case treated with radiosurgery. In our series surgery was found as the elective therapy for patients with glomus tumour of the temporal bone with no recurrences after 8 years of follow-up. Pre-operative embolization diminishes surgery time and intraoperative bleeding. Stereotaxic therapy cannot provide tumour growth control. Complications are discussed and compared with the bibliography.

This retrospective study was carried out in 36 children with cochlear implants under the age of 6. All had profound congenital bilateral sensorineural hearing impairment, without cochlear malformation. Fifteen children were diagnosed as having DFNB1 and homozygous 30-35delG mutation, and 21 had no mutation of Connexin 26 (Cx26). All of them used Nucleus 24K or ST cochlear implants, with complete non-traumatic insertion of the electrodes, and follow-up was 12 months. There is no significant difference in pure tone audiometry and logoaudiometric tests between the 2 groups, children diagnosed as having DFNB1 (homozygous 30-35delG mutation) and children without mutation of Cx26. However, the population with DFNB1 shows a tendency to achieve better results more quickly in vowels and bisyllabic word tests 12 months after implantation. The cochlear implant is an effective therapy for children with profound prelingual congenital hearing loss with mutation of Cx26.

Previous studies have explored speech perception in noise under various circumstances, but none have been specifically designed to explore the relevance of frequencies above 8 kHz and, more specifically, for the Spanish language. Twenty-nine subjects with NH, aged 19 to 55 years, and native speakers of the Spanish language listened to two sets of three disyllabic word lists with background noise. One set of words was unfiltered and included frequency components up to 22 kHz, and another set was band-pass filtered to include frequency components between 70 Hz and 8 kHz. Words were presented at 65 dB sound pressure level. Each set of words was presented with background noise with the same bandwidth limit as the accompanying list and adjusted to construct signal-to-noise ratio (SNR) conditions of +5, 0, and -5 dB. Results demonstrate a higher performance for unfiltered words at +5 and -5 dB SNR, although not at 0 dB SNR. For SNR +5 dB and -5 dB, the average success rate in word recognition was 17% higher when words were not filtered. For the case SNR = 0, however, both conditions yield statistically similar results. This study suggests that high-frequency components above 8 kHz contribute to speech understanding in noise for subjects with NH of the Spanish language. Given these findings, it would be interesting to determine if bandwidth limitations in current hearing prostheses may contribute to known difficulties with perception of speech in noise in hearing-impaired subjects.

There is controversy regarding the existence of an age limit after which a second implantation offers less benefit for the acquisition of communication skills. The objectives of this study were to confirm that sequential cochlear implantation offers benefits compared to unilateral implantation and to study whether, at 12 years of age, there are significant differences regarding the age at the time of the second implantation. Descriptive and observational study of a population of 12-year-old children carrying cochlear implants (n=69). A liminal pure tone audiometry and an open-field verbal discrimination test (disyllables, common phrases in an open context, with and without noise) were conducted to evaluate audiological benefits. Verbal discrimination results were better among patients who had been implanted before the age of 2 years, although the differences were not statistically significant (P>.5). Children who had received bilateral cochlear implants before the age of 2 years and with a period less than 4 years between both implants presented better verbal discrimination percentages (P<.05). In our sample, early cochlear implantation with a short period between both implants provided significant benefits regarding intelligibility. There seem to be a specific age and interimplant period, after which the auditory benefit on the first implant becomes reduced.
