Auditory Steady-State Response in the First Six Months of Life
Conclusion: The same threshold can be used as a normality reference for this age range, with distinct values for the different carrier frequencies. The influence of external auditory canal amplification should be taken into account.Audiol Neurotol Extra 2014;4:12-22 (Source: Audiology and Neurotology Extra)

Factors Contributing to Postural Sway in Patients with Diabetes in an In-Hospital Education Program
Conclusion: In patients with poorly controlled DM, postural sway was particularly associated with deterioration of motor nerve conduction study parameters represented by median nerve CMAP amplitude, tibial nerve CMAP conduction velocity, and peroneal nerve CMAP latency. A link between diabetic polyneuropathy, diabetes-related postural sway, and diabetes-related hearing loss was recognized.Audiol Neurotol Extra 2014;4:23-31 (Source: Audiology and Neurotology Extra)

Clinical and Microbiological Evaluation of an Extended-Wear Hearing Instrument
This study aimed to examine the integrity of the ear canal skin and its microbiological changes caused by an extended-wear hearing device. An extended-wear hearing device, Lyric2 (Phonak AG, Switzerland), which is the second generation of the Lyric device, was fitted to 52 ears of 27 subjects. A refit of the device was done for a selection of ears (n = 15) for which the initial fitting was interrupted (28 ears). A matching control group consisted of 10 ears of 10 subjects with no history of using any form of hearing aid for 3 months. The ear canal skin of ears fitted with the hearing device was inspected using an otoendosc...

Evaluation of Bone Tissue Formation in a Flat Surface Attachment of a Bone Conduction Implant: A Pilot Study in a Sheep Model
In this study, osseointegration of a flat passive BCI transducer dummy in sheep skulls was assessed using quantitative and qualitative histology as well as cone beam computed tomography (CBCT) and computed tomography (CT). The histology results were also related to the mechanical properties of the bone-to-implant interface. Eight months after the surgical implantation, histology sections of the bone close to the implant showed bone remodeling, compact bone and osseointegration. The histological findings corresponded well to the mechanical measurements indicating stiffer bone close to the implant and unaffected skull vibrat...

Validation of the U-STARR with the AB-York Crescent of Sound, a New Instrument to Evaluate Speech Intelligibility in Noise and Spatial Hearing Skills
This study primarily assesses the validity and reliability of the U-STARR compared to the Plomp test, which is the current Dutch gold standard for speech-in-noise testing. The outcome of both tests is a speech reception threshold in noise (SRTn). Secondary outcomes are the SRTn measured with sounds from spatially separated sources (SISSS) as well as sound localization capability. We tested 29 normal-hearing adults and 18 postlingually deafened adult patients with unilateral cochlear implants (CI). This study shows that the U-STARR is adequate and reliable and seems better suited for severely hearing-impaired persons than t...

Effects of Round Window Opening Size and Moisturized Electrodes on Intracochlear Pressure Related to the Insertion of a Cochlear Implant Electrode
Intracochlear pressure changes during the cochlear implant insertion are assumed to be an important contributor to hearing preservation. The aim was to observe intracochlear pressure changes by different round window opening sizes and different hydrophilic electrode conditions. The experiments were performed in a cochlear model with a micropressure sensor in the helicotrema area. Different artificial round window membrane and different moisturized electrode conditions were compared. A punctured round window causes a significantly higher and an indirect moisturized electrode condition a significantly lower intracochlear pre...

The Expression of TNF α, IL-6, IL-2 and IL-8 in the Serum of Patients with Idiopathic Sudden Sensorineural Hearing Loss: Possible Prognostic Factors of Response to Corticosteroid Treatment
Conclusions: TNF α and IL-6 can be used as prognostic factors for the treatment outcome, whereas the prognostic value of IL-8 requires further statistical confirmation.Audiol Neurotol Extra 2016;6:9-19 (Source: Audiology and Neurotology Extra)

Dietary Supplement Comprised of β-Carotene, Vitamin C, Vitamin E, and Magnesium: Failure to Prevent Music-Induced Temporary Threshold Shift
This study examined potential prevention of music-induced temporary threshold shift (TTS) in normal-hearing participants. A dietary supplement composed of β-carotene, vitamins C and E, and magnesium was assessed using a randomized, placebo-controlled, double-blind study design. Dosing began 3 days prior to the music exposure with the final dose consumed approximately 30-min pre-exposure. Post-exposure TTS was measured, with no significant difference as a function of treatment. Distortion product otoacoustic emission amplitudes were suppressed after music exposure in both groups, with no significant difference as a functio...
