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 […]

Hyperacusis is mainly a consequence of the noise level in the twenty-first century, owing to dramatic changes in people’s lifestyles. Of every 100 people with otological complaints (e.g., tinnitus and hyperacusis), 20 are affected by hyperacusis. Because of its high incidence, this symptom has long been the subject of investigation.Nine patients (eight female, one male) […]

Some authors have postulate that sistemic zinc can be employed in the threatment of tinnitus, because a sub-clinical hypozincemia is suposed to promote this auditory disturbance. However, in the majority of the cases of tinnitus, this hypozincemia was not confirmed. There is not enough randomized studies that could show the relationship between zinc and tinnitus. […]

We carried out a retrospective survey of 25 years of clinical experience with the use of clonazepam as a vestibular and tinnitus suppressant in the pharmacological treatment of vestibular or cochleovestibular disorders due to different causes.

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.

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.

Some new therapies for tinnitus employ bone-conducted sound in the high audio and ultrasonic frequencies, but there has been little previous research on sound transmission through the head at these frequencies.

Temporomandibular joint dysfunction in whiplash injuries is usual. The author describes the mechanism of this joint dysfunction and the physiopathology of tinnitus and associated balance disorders.

For assessment of safety, it is necessary to measure the maximum possible force exerted by a bone conduction device coupled to the human head.

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).
