Abstract Word‐learning skills were tested in normal‐hearing 12‐ to 40‐month‐olds and deaf 22‐ 12 18 months after cochlear implantation. Using the Intermodal Preferential Looking Paradigm (IPLP), children for their ability learn two novel‐word/novel‐object pairings. Normal‐hearing demonstrated learning on this task at approximately of age older. For children, performance was significantly correlated with early auditory experience: Children whose implants switched by 14 or who had relatively...
Current postoperative clinical outcome measures for adults receiving cochlear implants (CIs) consist of testing speech recognition, primarily under quiet conditions. However, it is strongly suspected that results on these may not adequately reflect patients' quality life (QOL) using their implants. This study aimed to evaluate whether QOL CI users depends recognition performance.Twenty-three postlingually deafened with CIs were assessed.Participants tested (Central Institute the Deaf word...
This study assessed phonological, lexical, and morphosyntactic abilities at 6th grade for a group of children previously tested 2nd to address 4 questions: (a) Do with cochlear implants (CIs) demonstrate deficits grade? (b) Are those greater, the same, or lesser in magnitude than observed (c) How do measured skills relate each other? (d) treatment variables affect outcome measures?Sixty-two graders (29 normal hearing, 33 CIs) participated, all whom had their language grade.Data are reported...
Objective To compare long‐term quality‐of‐life outcomes in vestibular schwannoma patients managed with observation, microsurgery, or stereotactic radiation. Study Design ross‐sectional survey retrospective chart review. Setting Tertiary care center. Subjects and Methods The Penn Acoustic Neuroma Quality of Life (PANQOL) was mailed to 600 treated for schwannoma. Patients were separated by treatment subsequently subdivided years follow‐up (0‐5, 6‐10, >10 years). Composite (cQOL) scores...
Models of speech recognition suggest that "top-down" linguistic and cognitive functions, such as use phonotactic constraints working memory, facilitate under conditions degradation, in noise. The question addressed this study was what happens to these functions when a listener who has experienced years hearing loss obtains cochlear implant.
Unexplained outcome variability exists among adults with cochlear implants (CIs). Two significant predictors are age and duration of deafness, older patients those longer durations deafness generally demonstrating poorer speech recognition. However, these factors often highly correlated. Thus, it is unclear whether outcomes should be attributed primarily to age-related declines or the experience auditory deprivation. Our aim was examine effects aging hearing loss on for postlingually deaf...
To evaluate diagnostic concordance of a synchronous telemedicine otolaryngology clinic with use currently available technology.Prospective.Patients in rural were enrolled pilot clinic. assess system fidelity, an on-site and remote (consulting) otolaryngologist conducted simultaneous patient evaluations using streaming telecommunication technology for all aspects the clinical encounter, including high-definition examination endoscopic images. Both physicians patients blinded diagnoses...
Significant variability in speech recognition outcomes is consistently observed adults who receive cochlear implants (CIs), some of which may be attributable to cognitive functions. Two hypotheses were tested: 1) preoperative skills assessed visually would predict postoperative at 6 months after CI; and 2) implantation result benefits processes months.Several executive functioning tasks have been identified as contributors with hearing loss. There also mounting evidence that can improve...
Cochlear implants (CIs) represent a significant engineering and medical milestone in the treatment of hearing loss for both adults children. In this review, we provide brief overview CI technology, describe benefits that CIs can to children who receive them, discuss specific limitations issues faced by users. We emphasize relevance linguistics community demonstrating how successfully access spoken language. Furthermore, research inform our basic understanding word recognition language...
Objective Unexplained variability in speech recognition outcomes among postlingually deafened adults with cochlear implants (CIs) is an enormous clinical and research barrier to progress. This only partially explained by patient factors (e.g., duration of deafness) auditory sensitivity spectral temporal resolution). study sought determine whether non‐auditory neurocognitive skills could explain exhibited adult CI users. Study Design Thirty CIs thirty age‐matched normal‐hearing (NH) controls...
Utilizing the cochlear implant to record electrophysiologic responses during device placement is a feasible and efficacious technique for monitoring near real-time physiology following electrode insertion.Minimizing intracochlear trauma implantation has emerged as highly researched area help improve patient performance. Currently, conventional technology allows recording of electrically evoked compound action potentials (eCAPs). Acoustically may be more sensitive in detecting physiologic...
Introduction With the growing popularity of telemedicine and tele-diagnostics, clinical validation new devices is essential. This study sought to investigate whether high-definition digital still images eardrum provide sufficient information make a correct diagnosis, as compared with gold standard view provided by microscopy. Methods Twelve fellowship-trained ear physicians (neurotologists) reviewed same set 210 otoscope images. Participants diagnosed each image normal or, if abnormal, they...
Objectives/Hypothesis Aural rehabilitation is not standardized for adults after cochlear implantation. Most implant (CI) centers in the United States do routinely enroll adult CI users focused postoperative programs due to poor reimbursement and lack of data supporting (or refuting) efficacy any one specific approach. Consequently, patients generally assume a self‐driven approach toward rehabilitation. This exploratory pilot study examined strategies pursued by with CIs associated these...
Abstract Background Postlingually deafened adult cochlear implant (CI) users routinely display large individual differences in the ability to recognize and understand speech, especially adverse listening conditions. Although have been linked several sensory (‘‘bottom-up’') cognitive (‘‘top-down’') factors, little is currently known about relative contributions of these factors high- low-performing CI users. Purpose The aim study was investigate functioning neurocognitive between on...
Acute infections of the middle ear are most commonly treated childhood diseases. Because complications affect children's language learning and cognitive processes, it is essential to diagnose these diseases in a timely accurate manner. The prevailing literature suggests that difficult accurately infections, even for experienced ear, nose, throat (ENT) physicians. Advanced care practitioners (e.g., nurse practitioners, physician assistants) serve as first-line providers many primary settings...
When listening to speech under adverse conditions, listeners compensate using neurocognitive resources. A clinically relevant form of is through a cochlear implant (CI), which provides spectrally degraded signal. CI often simulated noise-vocoding. This study investigated the mechanisms supporting recognition in adult users and normal-hearing (NH) peers noise-vocoded speech, with hypothesis that an overlapping set functions would contribute both groups. Ninety-seven adults either (54...
An improvement in speech perception is a major well-documented benefit of cochlear implantation (CI), which commonly discussed with CI candidates to set expectations. However, large variability exists outcomes. We evaluated the accuracy clinical predictions post-CI scores. In an online survey, clinicians involved care were asked predict 6-month performance on AzBio sentences and CNC words for 15 anonymised patients based demographic, medical, audiological data, preoperative recognition...
PURPOSE Several acoustic cues specify any single phonemic contrast. Nonetheless, adult, native speakers of a language share weighting strategies, showing preferential attention to some properties over others. Cochlear implant (CI) signal processing disrupts the salience cues: In general, amplitude structure remains readily available, but spectral less so. This study asked how well speech recognition is supported if CI users shift salient not weighted strongly by speakers. METHOD Twenty...
Objective: This study examined speech recognition in noise for children with hearing loss, compared it to normal hearing, and mechanisms that might explain variance children's abilities recognize noise. Design: Word was measured two levels of noise, both when the were co-located front came separately from one side. Four as factors possibly explaining variance: vocabulary knowledge, sensitivity phonological structure, binaural summation, head shadow. Study sample: Participants 113...
Objective Current clinical outcome measures for adults receiving cochlear implants (CIs) consist of word and sentence recognition, primarily under quiet conditions. However, these may not adequately reflect patients' CI‐specific quality life (QOL). This study first examined traditional auditory‐only speech recognition other potentially relevant auditory as correlates QOL in CI users. Second, scores on nonauditory tasks language cognition were potential predictors QOL. Study Design...
