A comparison of language achievement in children with cochlear implants and children using hearing aids. (1/432)English language achievement of 29 prelingually deaf children with 3 or more years of cochlear implant (CI) experience was compared to the achievement levels of prelingually deaf children who did not have such CI experience. Language achievement was measured by the Rhode Island Test of Language Structure (RITLS), a measure of signed and spoken sentence comprehension, and the Index of Productive Syntax (IPSyn), a measure of expressive (signed and spoken) English grammar. When the CI users were compared with their deaf age mates who contributed to the norms of the RITLS, it was found that CI users achieved significantly better scores. Likewise, we found that CI users performed better than 29 deaf children who used hearing aids (HAs) with respect to English grammar achievement as indexed by the IPSyn. Additionally, we found that chronological age highly correlated with IPSyn levels only among the non-CI users, whereas length of CI experience was significantly correlated with IPSyn scores for CI users. Finally, clear differences between those with and without CI experience were found by 2 years of post-implant experience. These data provide evidence that children who receive CIs benefit in the form of improved English language comprehension and production. (+info)
Comparison of three-dimensional visualization techniques for depicting the scala vestibuli and scala tympani of the cochlea by using high-resolution MR imaging. (2/432)BACKGROUND AND PURPOSE: Cochlear implantation requires introduction of a stimulating electrode array into the scala vestibuli or scala tympani. Although these structures can be separately identified on many high-resolution scans, it is often difficult to ascertain whether these channels are patent throughout their length. The aim of this study was to determine whether an optimized combination of an imaging protocol and a visualization technique allows routine 3D rendering of the scala vestibuli and scala tympani. METHODS: A submillimeter T2 fast spin-echo imaging sequence was designed to optimize the performance of 3D visualization methods. The spatial resolution was determined experimentally using primary images and 3D surface and volume renderings from eight healthy subjects. These data were used to develop the imaging sequence and to compare the quality and signal-to-noise dependency of four data visualization algorithms: maximum intensity projection, ray casting with transparent voxels, ray casting with opaque voxels, and isosurface rendering. The ability of these methods to produce 3D renderings of the scala tympani and scala vestibuli was also examined. The imaging technique was used in five patients with sensorineural deafness. RESULTS: Visualization techniques produced optimal results in combination with an isotropic volume imaging sequence. Clinicians preferred the isosurface-rendered images to other 3D visualizations. Both isosurface and ray casting displayed the scala vestibuli and scala tympani throughout their length. Abnormalities were shown in three patients, and in one of these, a focal occlusion of the scala tympani was confirmed at surgery. CONCLUSION: Three-dimensional images of the scala vestibuli and scala tympani can be routinely produced. The combination of an MR sequence optimized for use with isosurface rendering or ray-casting algorithms can produce 3D images with greater spatial resolution and anatomic detail than has been possible previously.

Cochlear implantations in Northern Ireland: an overview of the first five years. (3/432)During the last few years cochlear implantation (CI) has made remarkable progress, developing from a mere research tool to a viable clinical application. The Centre for CI in the Northern Ireland was established in 1992 and has since been a provider of this new technology for rehabilitation of profoundly deaf patients in the region. Although individual performance with a cochlear implant cannot be predicted accurately, the overall success of CI can no longer be denied. Seventy one patients, 37 adults and 34 children, have received implants over the first five years of the Northern Ireland cochlear implant programme, which is located at the Belfast City Hospital. The complication rates and the post-implantation outcome of this centre compare favourably with other major centres which undertake the procedure. This paper aims to highlight the patient selection criteria, surgery, post-CI outcome, clinical and research developments within our centre, and future prospects of this recent modality of treatment.

Prevalence of mitochondrial gene mutations among hearing impaired patients. (4/432)The frequency of three mitochondrial point mutations, 1555A-->G, 3243A-->G, and 7445A-->G, known to be associated with hearing impairment, was examined using restriction fragment length polymorphism (RFLP) analysis in two Japanese groups: (1) 319 unrelated SNHL outpatients (including 21 with aminoglycoside antibiotic injection history), and (2) 140 cochlear implantation patients (including 22 with aminoglycoside induced hearing loss). Approximately 3% of the outpatients and 10% of the cochlear implantation patients had the 1555A-->G mutation. The frequency was higher in the patients with a history of aminoglycoside injection (outpatient group 33%, cochlear implantation group 59%). One outpatient (0.314%) had the 3243A-->G mutation, but no outpatients had the 7445A-->G mutation and neither were found in the cochlear implantation group. The significance of the 1555A-->G mutation, the most prevalent mitochondrial mutation found in this study of a hearing impaired population in Japan, among subjects with specific backgrounds, such as aminoglycoside induced hearing loss, is evident.

Functional plasticity of language-related brain areas after cochlear implantation. (5/432)Using PET, the cerebral network engaged by heard language processing in normal hearing subjects was compared with that in patients who received a cochlear implant after a period of profound deafness. The experimental conditions were words, syllables and environmental sounds, each controlled by a noise baseline. Four categories of effect were observed: (i) regions that were recruited by patients and controls under identical task conditions: the left and right superior temporal cortices and the left insula were activated in both groups in all conditions; (ii) new regions, which were recruited by patients only: the left dorsal occipital cortex showed systematic activation in all conditions versus noise baselines; (iii) regions that were recruited by both groups with a different functional specificity; e.g. Wernicke's area responded specifically to speech sounds in controls but was not specialized in patients; and (iv) regions that were activated in one group more than the other: the precuneus and parahippocampal gyrus (patients more than controls) and the left inferior frontal, left posterior inferior temporal and left and right temporoparietal junction regions (controls more than patients). These data provide evidence for altered functional specificity of the superior temporal cortex, flexible recruitment of brain regions located within and outside the classical language areas and automatic contribution of visual regions to sound recognition in implant patients.

Use of audiovisual information in speech perception by prelingually deaf children with cochlear implants: a first report. (6/432)OBJECTIVE: Although there has been a great deal of recent empirical work and new theoretical interest in audiovisual speech perception in both normal-hearing and hearing-impaired adults, relatively little is known about the development of these abilities and skills in deaf children with cochlear implants. This study examined how prelingually deafened children combine visual information available in the talker's face with auditory speech cues provided by their cochlear implants to enhance spoken language comprehension. DESIGN: Twenty-seven hearing-impaired children who use cochlear implants identified spoken sentences presented under auditory-alone and audiovisual conditions. Five additional measures of spoken word recognition performance were used to assess auditory-alone speech perception skills. A measure of speech intelligibility was also obtained to assess the speech production abilities of these children. RESULTS: A measure of audiovisual gain, "Ra," was computed using sentence recognition scores in auditory-alone and audiovisual conditions. Another measure of audiovisual gain, "Rv," was computed using scores in visual-alone and audiovisual conditions. The results indicated that children who were better at recognizing isolated spoken words through listening alone were also better at combining the complementary sensory information about speech articulation available under audiovisual stimulation. In addition, we found that children who received more benefit from audiovisual presentation also produced more intelligible speech, suggesting a close link between speech perception and production and a common underlying linguistic basis for audiovisual enhancement effects. Finally, an examination of the distribution of children enrolled in Oral Communication (OC) and Total Communication (TC) indicated that OC children tended to score higher on measures of audiovisual gain, spoken word recognition, and speech intelligibility. CONCLUSIONS: The relationships observed between auditory-alone speech perception, audiovisual benefit, and speech intelligibility indicate that these abilities are not based on independent language skills, but instead reflect a common source of linguistic knowledge, used in both perception and production, that is based on the dynamic, articulatory motions of the vocal tract. The effects of communication mode demonstrate the important contribution of early sensory experience to perceptual development, specifically, language acquisition and the use of phonological processing skills. Intervention and treatment programs that aim to increase receptive and productive spoken language skills, therefore, may wish to emphasize the inherent cross-correlations that exist between auditory and visual sources of information in speech perception.

Cross-modal plasticity underpins language recovery after cochlear implantation. (7/432)Postlingually deaf subjects learn the meaning of sounds after cochlear implantation by forming new associations between sounds and their sources. Implants generate coarse frequency responses, preventing place-coding fine enough to discriminate sounds with similar temporal characteristics, e.g., buck/duck. This limitation imposes a dependency on visual cues, e.g., lipreading. We hypothesized that cross-modal facilitation results from engagement of the visual cortex by purely auditory tasks. In four functional neuroimaging experiments, we show recruitment of early visual cortex (V1/V2) when cochlear implant users listen to sounds with eyes closed. Activity in visual cortex evolved in a stimulus-specific manner as a function of time from implantation reflecting experience-dependent adaptations in the postimplant phase. (+info)
Some measures of verbal and spatial working memory in eight- and nine-year-old hearing-impaired children with cochlear implants. (8/432)OBJECTIVE: The purpose of this study was to examine working memory for sequences of auditory and visual stimuli in prelingually deafened pediatric cochlear implant users with at least 4 yr of device experience. DESIGN: Two groups of 8- and 9-yr-old children, 45 normal-hearing and 45 hearing-impaired users of cochlear implants, completed a novel working memory task requiring memory for sequences of either visual-spatial cues or visual-spatial cues paired with auditory signals. In each sequence, colored response buttons were illuminated either with or without simultaneous auditory presentation of verbal labels (color-names or digit-names). The child was required to reproduce each sequence by pressing the appropriate buttons on the response box. Sequence length was varied and a measure of memory span corresponding to the longest list length correctly reproduced under each set of presentation conditions was recorded. Additional children completed a modified task that eliminated the visual-spatial light cues but that still required reproduction of auditory color-name sequences using the same response box. Data from 37 pediatric cochlear implant users were collected using this modified task. RESULTS: The cochlear implant group obtained shorter span scores on average than the normal-hearing group, regardless of presentation format. The normal-hearing children also demonstrated a larger "redundancy gain" than children in the cochlear implant group-that is, the normal-hearing group displayed better memory for auditory-plus-lights sequences than for the lights-only sequences. Although the children with cochlear implants did not use the auditory signals as effectively as normal-hearing children when visual-spatial cues were also available, their performance on the modified memory task using only auditory cues showed that some of the children were capable of encoding auditory-only sequences at a level comparable with normal-hearing children. CONCLUSIONS: The finding of smaller redundancy gains from the addition of auditory cues to visual-spatial sequences in the cochlear implant group as compared with the normal-hearing group demonstrates differences in encoding or rehearsal strategies between these two groups of children. Differences in memory span between the two groups even on a visual-spatial memory task suggests that atypical working memory development irrespective of input modality may be present in this clinical population.

Background. Cochlear implants have become an accepted and successful treatment for profound sensorineural deafness in both children and adults. Essential to the effective and efficient localized stimulation of the auditory nerves, is the position of the implant electrode array stimulating sites within the scala tympani (ST). However, the small size, delicate internal structures and helical shape of the cochlear chambers complicate the matter of precise positioning of the implant electrode array. The design, fabrication process, and in vitro testing of a fluid actuator to steer a thin-film electrode array is presented. The application chosen to show feasibility is for a cochlear implant, however, the actuator might be used for cortical electrode arrays, for example. Method of Approach. The actuator functions by a change of internal fluid pressure within one or more flattened and curled polymer microtubes, expanding the highly elliptical cross section of each tube thereby stiffening it and causing ...

0115]At decision block 312, if it is determined that the measured response is an ECR waveform, at step 318 the intracochlear electrode associated with the frequency of the tone that generated the response is identified. At step 320, the map of the cochlear stimulation system is adjusted by setting the T level for e(j), Te(j), for electrode e(j) to the current stimulation level used to generate the response, which is A. At step 322, the center frequency of e(j), fce(j), is removed from the set of frequencies that are to be included in the next configuration of the sound stimulation signal. At step 324, N is decremented to indicate that one less intracochlear electrode is left to be adjusted during the fitting. Decision block 326 checks to see if the last intracochlear electrode has been adjusted. If N is not 0, the next sound stimulation signal is configured at step 306. The process then continues at steps 308, 310 and decision block 312 as described above. If at decision block 326, N has reached ...

Examining Multiple Sources of Influence on the Reading Comprehension Skills of Children Who Use Cochlear Implants | Journal of...
Children with profound deafness are at risk for serious reading difficulties. Multiple factors affect their development of reading skills, including use of cochlear implants. Further, multiple factors influence the overall success that children experience with their cochlear implants. These factors include the age at which they receive an implant, method of communication, vocabulary skills, preoperative residual hearing, and socioeconomic status. Ninety-one children with prelingual and profound hearing impairments who received cochlear implants at varying ages participated in the study. Structural equation modeling confirmed that multiple factors affected young cochlear implant users reading comprehension skills and that there were significant associations between the predictors of reading comprehension. Pre-implant vocabulary had an indirect positive effect on reading through postimplant vocabulary, which had a direct positive effect on reading. Overall, children with stronger language skills ...

Universal newborn hearing screening has allowed for the identification of severe to profound hearing loss at birth or within a few months thereafter. Because universal hearing screening programs have been and continue to be established throughout the United States, between 85% and 99% of newborns are being screened for hearing loss within 1 day of being born, with the remainder being tested within the first few months of life. This new population of hearing-impaired infants, who by virtue of the extent of their hearing losses are possible candidates for cochlear implantation, provides new opportunities and challenges.. Research over time has demonstrated that the early identification of significant hearing loss followed by intervention procedures, including hearing aid usage commencing during the first 6 months of life, significantly increases the level of language development, speech intelligibility, and emotional stability as compared with children with later identification and ...
Cochlear implantation in 3 patients with osteogenesis imperfecta: imaging, surgery and programming issues.
Osteogenesis imperfecta (OI) is a heterogeneous disease of the connective tissue caused by a defective gene that is responsible for the production of collagen type I, leading to defective bone matrix and connective tissue. Hearing loss affects 35-60% of the patients and will progress to deafness in 2-11% of OI patients for whom cochlear implantation may become the only remaining treatment option. Three patients with OI were retrieved from the Nijmegen Cochlear Implant Centres database. Most of the specific observations in ear surgery on patients with OI, such as brittle scutum, sclerotic thickening of the cochlea, hyperplastic mucosa in the middle ear and persistent bleeding, were encountered in these 3 patients. In case 3, with severe deformities on the CT scan, misplacement of the electrode array into the horizontal semicircular canal occurred. In all 3 cases, programming was hindered by nonauditory stimulation. Even after reimplantation, nonauditory sensations lead to case 3 becoming a ...

by Susan Boswell These are often the first words spoken when a cochlear implant recipients processor is turned on. And they have been a rite of passage for more than 36,000 people around the world who have received cochlear implants over the last two decades. Technological advances have brought dramatic changes in candidacy criteria, opening the door for more people with severe and profound hearing losses to choose this option.. When the U.S. Food and Drug Administration (FDA) first approved a cochlear implant with a single electrode for adults in 1985 and for children in 1990, only those who were almost completely deaf and could only perceive vibrations with a hearing aid could qualify.. Today, children and adults who were not candidates just two years ago may well be considered as candidates. The age of pediatric candidates has dropped from 2 years to as young as 12 months, and eligibility criteria for adults continue to expand.. A growing body of research has demonstrated that children who ...

Purpose: The purpose of this study was to examine the rate of progress in the 2nd implanted ear as it relates to the 1st implanted ear and to bilateral performance in adult sequential cochlear implant recipients. In addition, this study aimed to identify factors that contribute to patient outcomes. Method: The authors performed a prospective longitudinal study in 21 adults who received bilateral sequential cochlear implants. Testing occurred at 6 intervals: prebilateral through 12 months postbilateral implantation. Measures evaluated speech recognition in quiet and noise, localization, and perceived benefit. Results: Second ear performance was similar to 1st ear performance by 6 months postbilateral implantation. Bilateral performance was generally superior to either ear alone; however, participants with shorter 2nd ear length of deafness (|20 years) had more rapid early improvement and better overall outcomes than those with longer 2nd ear length of deafness (|30 years).

A cochlear implant (CI) is an electronic device that can provide a sense of hearing to deaf or profoundly hearing impaired listeners by directly activating auditory nerve fibers. Optimal auditory performance with a CI requires subject-specific adjustments of several system parameters, i.e. the CI needs to be "fitted" to the individual user. A large number of system parameters is available to the clinician in the fitting software. For some of these parameters it is essential that they are individualized prior to switching on the device, since they ensure that sounds are audible without making sounds uncomfortably loud. For other parameters subject-specific optimization is less essential and a one-size-fits-all approach of using default settings results in good performance for the majority of CI users. However, these default settings may not always result in optimal settings for individual CI users and subject-specific fine-tuning of these parameter settings may further improve performance and/or ...

US7497001B2 - Technique for predicting over insertions for partial grids and defective Z-pins - Google Patents
In accordance with the present invention, there is provided a technique which may be used in conjunction with an automated Z-pin insertion process to automatically monitor the insertion energy applied to the Z-pins during the initial insertion phase of the automated insertion process, and compare it to an empirically derived value for good insertions, thereafter allowing the insertion process to continue to a predetermined additional insertion depth before terminating the process. The insertion energy is calculated by cumulatively summing the insertion force and multiplying it by the insertion time, thus yielding the cumulative energy. At a specified, predetermined insertion depth, the energy accumulation is stopped and the value at the initial insertion depth is stored and compared to an empirically derived value. If the value is less than the empirical value, the insertion energy is too low, thus indicating that either a partial grid insertion is being encountered or defective Z-pins are being
We learned that Dr. Choo does believe bilateral implantation provides a child with some benefit, but not enough where he is doing the bilateral implantation at the same time as standard practice. He said that it doubles the length of the surgery and that getting insurance approval is difficult. This does not mean that he is opposed to doing them at the same time, just that it is not his standard choice ...

Can you have implantation bleeding day after sex - Bleeding day after sex implantation bleeding? No. Implantation bleeding occasionally occurs as the embryo attaches to the uterine lining. Implantation begins about 6 days after ovulation. Spotting a day after intercourse would not be implantation from an embryo formed on that day.
spotting or blood in discharge so just ignore those people who say what theres look like every women is different ok . Is it normal to get blood clots during implantation bleeding? . How many days does implantation bleeding last? Implantation bleeding is usually a little bit of spotting over 1 or 2 days, nothing like a period ...
Implantation bleeding 5 weeks pregnant - Can you have implantation bleeding at 5 weeks pregnant? No. Definitely not. You can have bleeding at 5 weeks for many reasons, but it is not implantation, that happened almost a month before.
Is there spotting during implantation only if ure pregnant or do u spot before your period during this time anyway?? And what exactly happens during this time (implantation)??
Transmastoid labyrinthotomy approach for cochlear implantation in a common cavity malformation: A case report | Ear, Nose &...
The standard transmastoid facial recess approach has become the popular technique for cochlear implantation. Although this approach has been used for implantation in patients with common cavity malformations, in patients with this anomaly and severe abnormalities of the middle ear, this approach may be technically difficult and makes the facial nerve vulnerable to injury. Using a direct approach to the common cavity through the mastoid cavity, we have successfully performed cochlear implantation in 1 patient with a common cavity malformation. This transmastoid labyrinthotomy approach to the common cavity is an effective and simple technique for placing the electrode array. It minimizes the risk to the facial nerve and may decrease postoperative cerebrospinal fluid leaks.. ...
Loudness balance between acoustic and electric stimulation by a patient with a multichannel cochlear implant<...
TY - JOUR. T1 - Loudness balance between acoustic and electric stimulation by a patient with a multichannel cochlear implant. AU - Dorman, Michael. AU - Smith, L.. AU - Parkin, J. L.. PY - 1993/8. Y1 - 1993/8. N2 - Estimates of loudness balance were obtained for acoustically and electrically presented 250 Hz sine signals from a patient who uses the Ineraid multichannel cochlear implant. Acoustic and electric loudness matching was possible because the patient evidenced a 25 dB HL threshold at 250 Hz in his nonimplanted ear. The level of the electrical stimulus in microamperes required for a balance of loudness grew linearly with equal increments in decibels for the acoustic stimulus. These data, in concert with the very limited data from previous studies, provide a rationale for using a logarithmic transformation of acoustic to electric intensity in signal processors for cochlear implants.. AB - Estimates of loudness balance were obtained for acoustically and electrically presented 250 Hz sine ...
Single or Multi-Channel Cochlear Implants Cochlear implants are recognized as an effective treatment of sensorineural deafness. While use of a unilateral cochlear implant in an individual with severe to profound hearing loss has become a standard clinical practice, bilateral implantation is less common. Evolution of cochlear implant devices has focused on minimizing the internally implanted electrodes, such that one device, the Nucleus® 24 (Cochlear Americas, Englewood, CO), received FDA approval (2000) for use in children 12 months of age and older. A review of the early peer-reviewed literature includes several reports on individuals with bilateral cochlear implants (Long, 2003; Muller, 2002; Schoen, 2005; Tyler, 2002; van Hoesel, 2002; van Hoesel, 2003). These early reports evaluated small numbers of individuals and provided limited outcome information. In these reports, most, but not all, individuals reported very slight to modest improvements in sound localization and speech ...

Cochlear implantation following treatment for medulloblastoma - Roland - 2009 - The Laryngoscope - Wiley Online Library
Treatment of pediatric medulloblastoma, the most common malignant tumor of the CNS in children, requires a combination of surgical excision, radiation therapy, and chemotherapy. Prior research has documented ototoxicity and middle ear disease in 25% to 90% of patients treated with multimodality therapy.5, 7, 11 At this institution, pediatric medulloblastoma patients receive a cumulative cisplatin dose of 300 mg, decreased from the standard of 600 mg. Early analysis suggests that this reduction may minimize ototoxic sequelae, however long-term data on SNHL is lacking. Further, the percentage of patients in this population that will ultimately qualify for cochlear implantation has not yet been documented.. Damage to the auditory system from chemotherapeutic agents, specifically platinum-based compounds, as well as radiation therapy is well documented. Cisplatinum ototoxicity is typically characterized by irreversible, bilateral, symmetric, high-frequency SNHL.5, 7 Ototoxicity can be related to ...

A cochlear implant is an electronic device that transmits electrical impulses to the brain where they are perceived as sounds both for children who are born deaf or become deaf and also deaf or severely hard of hearing adults.. The cochlear implant consists of two parts:. - the external part with a speech processor incorporating a microphone which is placed behind the ear with a transmitter coil or with a compact, single-unit audio processor that is held in place by magnets over the implanted receiver. - a surgically implanted internal part consisting of a receiver package implanted in a recess in the mastoid bone which is connected to the electrode array positioned within the cochlea.. Today the possibility of obtaining a cochlear implant in Europe is still very uneven and depends in particular on the social insurance system of the country concerned.. It should be remembered that health policy in the European Union is in the first place the responsibility of each state member.. Numerous ...

This update explores the importance of early auditory stimulation by considering the development of speech processing skills in profoundly deaf children who have received a cochlear implant. This literature is relevant to issues affecting children with Down syndrome, because like them, children with cochlear implants have hearing difficulties, but unlike the former, they do not have oral-motor issues.

Auditory evoked potentials (AEP) are highly demanded during the whole process of equipping patients with cochlear implants (CI). They play an essential role in preoperative diagnostics, intraoperative testing, and postoperative monitoring of auditory performance and success. The versatility of AEPs is essentially enhanced by their property to be evokable by acoustic as well as electric stimuli. Thus, the electric responses of the auditory system following acoustic stimulation and recorded by the conventional surface technique as well as by transtympanic derivation from the promontory (Electrocochleography [ECochG]) are used for the quantitative determination of hearing loss and, additionally, electrically evoked compound actions potentials (ECAP) can be recorded with the intracochlear electrodes of the implant just adjacent to the stimulation electrode to check the functional integrity of the device and its coupling to the auditory system ...
If you have moderate to profound hearing loss and hearing aids are no longer helping, a cochlear implant could be an effective option for you.
Objective:The purpose of this investigation is to conduct a systematic review of the long-term speech-recognition outcomes of ABIs in postlingually deafened adults, and to compare outcomes of ABIs in adults with NF2/tumors to adults without NF2. Methods: A comprehensive search utilizing various peer reviewed databases via the City University of New York (CUNY) Graduate Center Library was conducted to identify relevant studies investigating speech-recognition outcomes in ABI patients with postlingual deafness, both with and without tumors. Inclusion criteria included studies that involved at least one adult ABI patient (with or without NF2) with postlingual deafness, who was seen for follow-up auditory performance testing at one-year post-activation or later. Results: Thirteen articles met inclusion criteria for this systematic review. The studies utilized various materials for speech-recognition assessment to evaluate speech-recognition performance. Because of the great diversity among the materials
EDITORIAL USE ONLY: Surgeon Michael Pringle holds the internal parts of a binaural cochlear implant device. The circular part sits under the skin against the skull with the shorter electrode array going into the cochlea on that side of the head. The longer array runs under the skin across the top of the skull to the cochlea in the other ear. External microphones and processors determine the stimulation to be applied to the internal arrays to give effective stereo hearing. Photographed at Southampton General Hospital, UK.
Cochlear implant, 3D coloured computed tomography (CT) scan. This device is implanted in the scalp, connected to the ear and the brain. The external component (microphone and sound processor) is worn on the ear. Alead takes the sound to the transmitter part of the device, which is magnetically bound to the internal component which has been surgically placed on the skull under the skin (pink, blue and green areas). The internal component converts the sound signal into electrical impulses sent to electrodes (yellow) implanted in the cochlea, the organ of hearing, allowing those with hearing losses to regain a sense of hearing. - Stock Image C036/8952

PORA stands for "call for action" among the target audience to upgrade their knowledge and network with the aim of further improving CI practice on a global basis and thus delivering better quality and more efficient care to children suffering from hearing loss. PORA is here to promote use of modern methods of communication among parents and thus develop a strong network of like-minded individuals sharing the same values, aspirations, and most importantly, needs.. Its time to get connected for the benefit of ourselves - therapists and parents - and of our children!. PORA offers you:. ...
As was the case for first generation cochlear implants, early sight recovery devices have relied on straightforward signal processing and encoding schemes that assume that the transformation from stimulation to percept is virtually linear: these models presume that stimulating a grid of positions on the retina leads to the corresponding percept of a grid of luminous dots. However, a variety of psychophysical [19-24] and retinal  data, as well as the potential distortions described in this review, suggest that this linear scoreboard model is inadequate as an encoding model. To take the development of cochlear implant technology as a guide, a combination of psychophysical and neurophysiological research has led to dramatic improvements in cochlear implant coding schemes over the years. Indeed, for cochlear implants it could be argued that improvements in encoding have been as important as improvements in physical technology in improving perceptual outcomes [26,27].. Two main ways of ...

Aim. To study the efficacy of vagus nerve stimulation (VNS) therapy in a highly drug-resistant childhood epilepsy patient group and to investigate the effect of age at implantation on efficacy. Methods. The efficacy of VNS treatment was analysed in a cohort of 70 patients with drug-resistant epilepsy. Both children with focal (n=16) and generalized epilepsies (n=54) were included. Age at implantation varied between 19 months and 25 years. Results. Overall, responder rate was 54% with 5.7% children becoming seizure-free. The only factor in our analysis that could predict good outcome was age at implantation. In the youngest group ...
A prelingual deaf individual is someone who was born with a hearing loss, or whose hearing loss occurred before they began to speak. Infants usually start saying their first words around one year. Therefore a prelingually deaf typically was either born deaf or lost their hearing before the age of one (the age when most hearing loss in children occurs). Congenital (present at birth) hearing loss is also considered prelingually, since a newborn infant has not acquired speech and language. Each year in the United States, approximately 12,000 babies are born with hearing loss. Profound hearing loss occurs in somewhere between 4 to 11 per every 10,000 children. Prelingual hearing loss can be either acquired, meaning it occurred after birth due to illness or injury, or it can be congenital, meaning it was present at birth. Congenital hearing loss can be caused by genetic or nongenetic factors. The nongenetic factors account for about one fourth of the congenital hearing losses in infants. These ...
