The developement of new cochlear implant devices allows the opportunity to use more sophisticated speech encoding strategies. The Nucleus 24 channels cochlear implant system offers the possibility to compare different strategies within the same patient. The aim of this study was to determine the optimal map by changing the three available speech encoding strategies (SPEAK, […]
The aim of this study was to elaborate an algorithm of the detection of brainstem lesion according BAEP changes. The following questions were raised for this purpose: 1) which interpretation strategy of BAEP changes selects the most patients with brainstem lesions? 2) which BAEP abnormalities differentiate between mass lesions of posterior fossa and demyelinating encephalomyelitis? […]
Advances in basic research in neurosciences and the introduction of new non-invasive techniques, that make possible the detection of weak signals of the brain, have revolutionized diagnosis and treatment. The most often used methods for functional imaging of the human brain are positron emission tomography (PET) and functional magnetic resonance imaging (fMRI). More recently, a […]
Several prognostic indicators of favorable outcome in idiopathic sudden sensorineural hearing loss (ISSHL) have been proposed: an initial profound hearing loss, a down-sloping audiometric curve, advanced age, and the presence of vertigo. The latter has been disputed in the literature. The present study addressed the correlation between vertigo and outcome of ISSHL. Sixty-seven patients with […]
Audiograms and auditory evoked magnetic fields (AEFs) were observed in young male and female adults at different ages before and after being exposed to discotheque music for 4 hours. Sound pressure levels (SPLs) ranged from 95 dB (SPL) up to 130 dB (SPL).
All of 1,420 children seen for clarification of a hearing disorder or to follow up for known difficulty in hearing were questioned as to whether they experienced tinnitus. The interview was carried out after a hearing test was conducted, which was based on play audiometry or normal pure-tone threshold audiometry, depending on the age of […]
The aim of this study was to highlight the clinical characteristics of tinnitus and to attempt a quantitative assessment in relation to any underlying etiologies. We undertook to study a population of 123 patients attending a tinnitus clinic between 1998 and 2000.
The application of slow vertex response audiometry (cortical evoked response audiometry), mainly in the diagnosis of pseudohypoacusis, is reported. This procedure is of interest in forensic audiology.
During the last half century, medical developments have expedited an increase of expectation of life, all over the world. This extension of life has made that some pathologies that in former years were considered of low prevalence, nowadays they have become top priority for public health.
This preliminary report is an account of 21 consecutive patients who had tinnitus of the severe disabling type and were examined with quantitative electroencephalography (QEEG).
