Some patients suffer hearing loss in the early postoperative period following vestibular schwannoma excision despite having intact hearing immediately after surgery. As this phenomenon has rarely been documented or described, the putative mechanism remains vague. The objective of the current study was to document the patterns of change in behavioural and electrophysiological responses in patien...

INTRODUCTION High-frequency audiometry may contribute to the early detection of hearing loss caused by ototoxic medications. Many ototoxic drugs are widely used in the treatment of patients with cystic fibrosis. Early detection of hearing loss should allow known harmful drugs to be identified before the damage affects speech frequencies. The damage caused by ototoxicity is irreversible, resulti...

Eight audiology students with little or no visual reinforcement audiometry (VRA) experience each performed a VRA test on an infant. Four of the students received approximately 5 hours of behavioral audiometry simulator (BAS) training, and 1 week later, after the first VRA test, all eight students tested a second infant. Student performance was rated by three audiologists who were experienced in...

The purpose of this study was to analyze the changes in the acoustically evoked cortical cognitive potentials N 200, P 300, and N 3 with age. There were 232 participants, who were 60 years or older, and each was examined using a battery of audiological tests including a questionnaire, otomicroscopy, pure-tone audiometry, and cortical cognitive potentials, measured at Fz using an auditory oddbal...

INTRODUCTION The present study investigated the relationship between the perceived tinnitus severity, depressive and anxiety symptoms in individuals with tinnitus. An attempt was also made to see if any relationship exists between the perceived tinnitus severity and the age, gender or hearing status of the sufferer. MATERIALS AND METHODS Fifty individuals (31 males, 19 females) with tinnitus ...

We undertook assessment of hearing in patients with cystic fibrosis who were taking part in a large randomized controlled trial of once- versus three-times-daily tobramycin for pulmonary exacerbations of cystic fibrosis (the TOPIC study). All patients were eligible to have standard pure tone audiometry performed across the frequency range of 0.25 to 8 kHz. High-frequency pure tone audiometry ov...

Using pure tone audiometry, we assessed the prevalence of hearing impairment in a sample of elderly people living at home and aged 70 or more. Deafness was defined as an average loss over the speech frequencies at 1 kHz, 2 kHz and 4 kHz of 35 db or more in the better ear. We found that 60 per cent of the sample were deaf. This figure is substantially higher than previous estimates arrived at wi...

Despite efforts to screen all babies for deafness within their first year, the handicap is still being detected later than is desirable. This study designed to evaluate the effectiveness of current audiometric screening programmes. Hearing tests were carried out on 535 infants between the ages of 6 months and one year using conventional tests, which depend on the infants' response to familiar s...

We performed a retrospective study of 131 patients who underwent microsurgical removal of statoacoustic neuroma at the University of Wuerzburg. Our goal was to evaluate objective audiovestibular findings prior to and after surgery. Our analysis focused on the evaluation of quantitative parameters in speech and pure-tone audiometry and on the reactivity of the vestibular system.
