Hua Ou, Ann Perreau, Richard Tyler
Purpose: The Spatial Hearing Questionnaire (SHQ) was developed to address how to measure spatial-hearing ability in complex listening situations (Tyler, Perreau, & Ji, 2009). It has been translated and validated into various languages, including Chinese, Dutch, French, and Persian. Although the SHQ contains only 24 items, it could be time-consuming in a busy clinic to administer. The purposes of this study were to develop and validate a shortened version of the SHQ (SHQ-S) and to compare self-perceived spatial-hearing ability across adults with normal hearing (NH), hearing loss (HL), and cochlear implants (CIs)...

OBJECTIVES: The main objective of this study was to measure the vibrotactile thresholds on the mastoid process and forehead positions using patients with bilateral deafness and to compare the results from the two bone conduction vibrators Radioear B71 and B81. DESIGN: There is a possibility that the vibrotactile sensation on the skin makes it difficult to discriminate between sound and vibration. The risk is highest for patients who have bone conduction hearing thresholds in proximity to or worse than their vibrotactile thresholds...

BACKGROUND: Non-syndromic autosomal dominant hearing impairment is characteristically postlingual in onset. Genetic diagnostics are essential for genetic counselling, disease prognosis and understanding of the molecular mechanisms of disease. To date, 36 causative genes have been identified, many in only individual families. Gene selection for genetic screening by traditional methods and genetic diagnosis in autosomal dominant patients has therefore been fraught with difficulty. Whole-exome sequencing provides a powerful tool to analyze all protein-coding genomic regions in parallel, thus allowing the comprehensive screening of all known genes and associated alterations...

Pitch plays a crucial role in speech and music, but is highly degraded for people with cochlear implants, leading to severe communication challenges in noisy environments. Pitch is determined primarily by the first few spectrally resolved harmonics of a tone. In implants, access to this pitch is limited by poor spectral resolution, due to the limited number of channels and interactions between adjacent channels. Here we used noise-vocoder simulations to explore how many channels, and how little channel interaction, are required to elicit pitch...

HYPOTHESIS: 1) Environmental sound awareness (ESA) and speech recognition skills in experienced, adult cochlear implant (CI) users will be highly correlated, and, 2) ESA skills of CI users will be significantly lower than those of age-matched adults with normal hearing. BACKGROUND: Enhancement of ESA is often discussed with patients with sensorineural hearing loss as a potential benefit of implantation and, in some cases, ESA may be a major motivating factor. Despite its ecological validity and patients' expectations, ESA remains largely a presumed skill...

OBJECTIVE: Although visual processing recruitment of the auditory cortices has been reported previously in prelingually deaf children who have a rapidly developing brain and no auditory processing, the visual processing recruitment of auditory cortices might be different in processing different visual stimuli and may affect cochlear implant (CI) outcomes. METHODS: Ten prelingually deaf children, 4 to 6 years old, were recruited for the study. Twenty prelingually deaf subjects, 4 to 6 years old with CIs for 1 year, were also recruited; 10 with well-performing CIs, 10 with poorly performing CIs...

OBJECTIVES: This study aimed to improve access to high-frequency interaural level differences (ILD), by applying extreme frequency compression (FC) in the hearing aid (HA) of 13 bimodal listeners, using a cochlear implant (CI) and conventional HA in opposite ears. DESIGN: An experimental signal-adaptive frequency-lowering algorithm was tested, compressing frequencies above 160 Hz into the individual audible range of residual hearing, but only for consonants (adaptive FC), thus protecting vowel formants, with the aim to preserve speech perception...

OBJECTIVES: With rising quality of speech perception in cochlear implant users, the indication widens. Nowadays, cochlear implantation is reasonable even in vestibular schwannoma patients. Speech perception with a cochlear implant is in these patients as promising as in patients with sensorineural hearing loss. However, the impact of cochlear implantation on vertigo and tinnitus after removal of vestibular schwannoma has not been investigated yet. METHODS: In a retrospective study, we analysed 12 patients treated with a cochlear implant after removal of vestibular schwannoma...

BACKGROUND: Guidelines established by the AAA currently recommend behavioral testing when fitting frequency modulated (FM) systems to individuals with cochlear implants (CIs). A protocol for completing electroacoustic measures has not yet been validated for personal FM systems or digital modulation (DM) systems coupled to CI sound processors. In response, some professionals have used or altered the AAA electroacoustic verification steps for fitting FM systems to hearing aids when fitting FM systems to CI sound processors...

Exposure of the cochlear implant electrode array as a late complication has been reported rarely in the literature. A retrospective analysis revealed 4 patients presenting with exposure of their cochlear implant electrode arrays from 2 to 17 years after implantation. Data collected from these 4 patients were surgical implantation approach, type of implant, age at implant, interval between implant and complication, surgical correction of the problem, pathology at the time of correction, and length of follow-up after intervention...

PURPOSE OF REVIEW: Minorities often lag behind in hearing loss evaluation and treatment. Our cochlear implant program aimed to identify the socioeconomic and cultural barriers that prevented our African-American cochlear implant candidates from seeking help for their hearing loss, specifically cochlear implant surgery. RECENT FINDINGS: Our pilot study surveyed 11 African-Americans with cochlear implants and identified obstacles that included patient-physician mistrust, social stigma, financial cost, and lack of education about the devices and procedures...

PURPOSE OF REVIEW: Children with congenital hearing loss are being identified earlier, leading to earlier intervention. Current US Food and Drug Administration (FDA) criteria states a child must be 12 months or older for cochlear implantation. The purpose of this article is to review recent publications regarding the benefits of implanting infants under 12 months of age. Topics include: safety and efficacy of surgery, speech and language acquisition outcomes, audiologic components, and limitations...

Modulations in temporal envelopes are a ubiquitous property of natural sounds and are especially important for hearing with cochlear implants (CIs) because these devices typically discard temporal fine structure information. With few exceptions, neural temporal envelope processing has been studied in both normal hearing (NH) and CI animals using only pure sinusoidal amplitude modulation (SAM) which poorly represents the diversity of envelope shapes contained in natural sounds because it confounds repetition rate and the width of each modulation cycle...

Sensorineural hearing loss (SNHL) is a heterogeneous family of hearing disabilities with congenital (including genetic) as well as acquired etiology. Congenital SNHL of genetic etiology is further sub-divided into autosomal dominant, autosomal recessive and X-linked SNHL. More than 60 genes are involved in the etiology of autosomal recessive non-syndromic hearing loss (ARNSHL) commonly manifesting as heterogeneous pre-lingual profound to severe non-progressive clinical phenotype. ILDR1-dependent ARNSHL (DFNB42, OMIM: # 609646) is a very rare sub-type of hearing disability, with unknown prevalence, caused by function-damaging genetic variants in ILDR1 gene reported in families of Middle-Eastern origin...

BACKGROUND: High-resolution computed tomography (HRCT) magnifies the role of preoperative imaging for detailed inner and middle ear anatomical information and enhances more efforts for better dependent correlation and measurements of round window (RW). OBJECTIVE: To find an applicable way by HRCT imaging for the prediction of the visibility of the RW during cochlear implantation (CI) surgery. METHODS: Five radiologic measurements were performed on the axial HRCT and these measurements were correlated with the degree of RW visibility after performing posterior tympanotomy during CI surgery...
