INTRODUCTION AND OBJECTIVES Some studies suggest that simultaneous or sequential cochlear implantation in a short period of time offers additional benefits. There is controversy regarding the existence of an age limit after which a second implantation offers less benefit for the acquisition of communication skills. The objectives of this study were to confirm that sequential cochlear implantati...

OBJECTIVES To review evidence of hearing loss as a risk factor for dementia. Data Sources: PubMed Review methods: A systematic review was conducted using the PubMed database using the search terms (hearing loss OR presbycusis) AND (dementia OR cognitive decline). Initially, 488 articles were obtained. Only those studies evaluating an association between hearing loss and incident dementia or cog...

BACKGROUND Hearing loss is one of the most common symptoms of mitochondrial disorders. However, audiological phenotypes associated with different molecular defects in mtDNA are not yet well characterized. MATERIAL AND METHODS A large cohort of 1499 nonconsanguineous patients aged 5-40 years with hearing loss of unknown etiology was screened for mutations in mtDNA. For further analysis, patien...

INTRODUCTION One of the problems observed in pure-tone audiometry tonal has been the variation in test results of a same individual, particularly at frequencies of 4kHz, 6kHz and/or 8kHz. Improper placement of headphones is one of the factors that can cause alterations in results. OBJECTIVE To compare differences in auditory thresholds using earphones positioned by the examiner and by the wor...

INTRODUCTION The aim of this study was to evaluate audiological outcomes following adenoidectomy by the classical method and by endoscopically-assisted adenoidectomy using a powered instrument (microdebrider). MATERIALS AND METHODS This study was conducted in a tertiary care center. It included 40 patients divided into two equal groups of 20 each. Group-A patients underwent classical adenoide...

With distance learning becoming more of a reality than a novelty in many undergraduate and graduate training programs, web-based clinical simulations can be identified as an instructional option in distance education that has both a sound pedagogical foundation and clinical relevance. The purpose of this article is to report on the instructional effectiveness of a web-based pure-tone audiometry...

In this study we investigated the risk of hearing loss among workers exposed to both toluene and noise. We recruited 58 workers at an adhesive materials manufacturing plant who were exposured to both toluene and noise [78.6-87.1 A-weighted decibels; dB(A)], 58 workers exposed to noise only [83.5-90.1 dB(A)], and 58 administrative clerks [67.9-72.6 dB(A)] at the same company. We interviewed part...

A prospective randomized controlled study was carried out to investigate the effect of prophylactic antibiotic ear drops used for five days after bilateral grommet insertion. The average improvement in the hearing threshold was significantly better in ears in which there was an effusion (16 dB) compared with no effusion (9 dB). The drops had no significant effect upon grommet function at three ...

CONCLUSIONS The results of this preliminary study demonstrate that with regard to determining the efficacy of intratympanic (IT) gentamicin treatment in patients with Meniere's disease, the reliability of testing for vestibular evoked myogenic potentials (VEMPs) is comparable to that of caloric tests. Compared with caloric tests, VEMP measurements are more comfortable and take less time. The re...
