Hearing

The etiology of tinnitus combines hereditary and environmental factors. To help develop optimal therapies for tinnitus, it is necessary to characterize the genetic contributors to the pathophysiology and to design treatments at the level of the gene. Inner ear gene therapy involves delivery of genes into the vestibular or auditory portions of the inner ear […]

This work intends to find hearing loss or audiometric shifts in a group of elementary students and intensity of noise to which these students are exposed.

The chemical element zinc has been in the last decades strongly studied. It is well known that it is present in some different structures of the Central Nervous System, acting as a co-factor of excitatory glutamatergic synapsis. Its function is not yet fully understood, but it seems to modulate the sensibility of glutamatergic post-sinaptic receptors […]

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).

This study was conducted in an attempt to determine the efficacy of neurofeedback (NFB) in the treatment of patients suffering from vertigo or tinnitus. Results indicated that after NFB, power for delta and theta bands was reduced; however, an increase of power was noted for the alpha bands.

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).

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).

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 […]

Tinnitus as a symptom remains a serious multidisciplinary problem. Vertigo or dizziness is not noticed frequently in tinnitus patients, so vestibular function is not often studied.

Transtympanic gentamicin administration has become a popular modality in the treatment of Ménière’s disease. This modality and other inner-ear medical therapy are gaining increased clinical and scientific attention.
