objectives: this study investigated the efficacy of working memory training for improving working memory capacity and related auditory stream segregation in auditory processing disorders children. methods: fifteen subjects (9-11 years), clinically diagnosed with auditory processing disorder participated in this non-randomized case-controlled trial. working memory abilities and auditory stream s...

BACKGROUND Total ossicular replacement prostheses (TORP) are often used to re-establish ossicular coupling of sound in an ear lacking a stapes supra-structure. The use of TORPs, however, is associated with a 2/3 five year failure rate due to their anatomic instability over time in the middle ear. The use of autologous fat to try and stabilize TORPs may improve long-term results with this challe...

To rehabilitate profoundly deaf patients who are not suitable for cochlear implants, central auditory prostheses have been implanted. To compare two possible electrode configurations - penetrating and surface ones - electrical stimulation of the cochlear nucleus with both types of arrays was tested on guinea pigs and cats. Electrophysiological, autoradiographic and histological measures were us...

Objective(s): We sought to explore whether neuregulin-1(NRG1) would have a protective effect on the auditory cortices of adult C57BL/6J mice.Materials and Methods: We used RTPCR and Western blot (WB) to detect the expression of NRG1 and ERBB4 (the receptor of NRG1) in the auditory cortices of C57BL/6J mice of different ages (6–8 weeks an...

Reconstruction of a facial defect is a complex modality either surgically or prosthetically, depending on the site, size, etiology, severity, age, and the patient’s expectation. The loss of an auricle, in the presence of an auditory canal, affects hearing, because the auricle gathers sound and directs it into the canal. The auricle acts as a resonator to slightly amplify lower frequency sounds ...

STUDY DESIGN Biomechanical analysis of a novel prosthesis based on the physiological curvature of endplate was performed. OBJECTIVE To compare the biomechanical differences between a novel prosthesis based on the physiological curvature of the endplate and the Prestige LP prosthesis after cervical disc replacement (CDR). SUMMARY OF BACKGROUND DATA Artificial disc prostheses have been widely...

Cochlear implant (CI) users suffer from elevated speech-reception thresholds and may rely on lip reading. Traditional measures of spatial release from masking quantify speech-reception-threshold improvement with azimuthal separation of target speaker and interferers and with the listener facing the target speaker. Substantial benefits of orienting the head away from the target speaker were pred...

OBJECTIVES This study measured the impact of auditory spectral resolution on listening effort. Systematic degradation in spectral resolution was hypothesized to elicit corresponding systematic increases in pupil dilation, consistent with the notion of pupil dilation as a marker of cognitive load. DESIGN Spectral resolution of sentences was varied with two different vocoders: (1) a noise-chann...

objectives: microtia is the most commonly seen congenital ear defect, and involves an auricular deformity either unilaterally or bilaterally. the aim of this study was to fabricate silicone prostheses for a child with bilateral microtia using an innovative technique. methods: this method involved the construction of bilateral ear prostheses using clips, which were located within the layers of t...
