Mathematical modelling for detection of brainstem lesions according abr changes
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? […]
Contribution of high click stimulus repetition rate in auditory evoked potentials in multiple sclerosis patients with normal mri
The purpose of this work was to evaluate if a stimulus reptition rate that is higher than 30 clicks/sec increases the sensitivity of the absolute latencies of waves I, III and V and interpeak intervals I-III, III-V and I-V in the Auditory Brainstem Responses.(ABR) of Multiple Sclerosis (MS) patients.
Effects of discotheque music on audiometric results and central acoustic evoked neuromagnetic responses
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).
Tinnitus in childhood
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 […]
Characteristics of tinnitus and etiology of associated hearing loss: a study of 123 patients
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.
Slow auditory evoked potentials: the end of malingering in audiology
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.
Quantitative electroencephalography: preliminary report—tinnitus
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).
Effects of noise on the intensity of distortion product otoacoustic emissions
Distortion product otoacoustic emission (DPOAE) is a widely used differential diagnostic method for diagnosing inner ear disorders. It provides us information on the condition of the outer hearing cells (OHCs).
Doppler ultrasonography in tinnitus patients
Tinnitus can be functionally measured and localized through sensorimotor and neurosensory tests. According to our Neurofisiología Otooftalmológica data bank, 60% of patients requiring a consultation have a history of cardiocirculatory disorders. This figure has moved us to study cerebrovascular processes in those patients seeking consultation for a tinnitus symptom only. The sudden appearance of the […]
