Hearing

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 […]

This reports recommends the consideration of development of additional outcome measures to be used as a battery of subjective self-assessment questionnaires for patients with tinnitus. The goal is improved overall care for the tinnitus patient. The name of the battery of outcome questionnaires is TOP. Five existing outcome measurements have been incorporated into the profile […]

Tinnitus is a common otological symptom. Usually it is subjective (perceived only by the patient); very rarely is it objective (heard by both the patient and the examiner). Objective tinnitus due to middle-ear myoclonus is extremely rare, with only a few case reports published in the literature. We present three cases of objective tinnitus caused […]

At the Psychiatric Clinic of Szeged we began a comprehensive investigation with the aim of etiological sub-grouping of schizophrenia. As work hypothesis we treat schizophrenia as a progressive neurodevelopmental, multi-factorial long latency period disorder with notable genetic definiteness whose development and existence also significantly involves the influence of the environment. This disorder is heterogeneous clinically […]

In this work we describe the Verrucous Carcinoma characteristics in the external auditory conduct. It is an infrequent tumor in that area, with an apparently innocuous cytology but locally an invader. In describing the clinic of this pathology, the necessary complementary studies to reach a sure diagnosis, the deferential diagnosis that must be taken into […]

Aim of study: Hearing loss caused by exposure to recreational noise is considered a devastating disability, not least because it is virtually 100 percent preventable. No consensus exists regarding the magnitude of the risk. This study prospectively assesses the hearing threshold in a group of Portuguese adolescents, related to their habits of noise exposure. Method: […]

The appearance of tinnitus has risen clearly also in children within the last decades. 1550 children were questioned as to whether they have tinnitus. A total of 131 children said at the interview that tinnitus had appeared or was still present. The most frequent information was the progression of an existing hardness of hearing followed […]

Masking of tinnitus is possible using high audio frequencies and low-frequency ultrasound. The mechanisms involved in reception and perception of both audio frequencies and ultrasound are identical, with the exception that ultrasound interacts with an intermediary site, the brain. We proposed brain ultrasonic demodulation as the means of place-mapping ultrasound on the first few millimeters […]

It has long been suspected that an important relationship exists between inner and outer hair cells, and that a disturbance of this relationship could lead to the phenomenon of tinnitus. The electromodel of the auditory system describes one mechanism of this inter-hair cell relationship. Following this model a mechanism exists, driven by mechanosensitive outer hair […]

Psychological aspects are often underlined in generation of tinnitus so we assessed the neuropsychological status in our group of patients. We also found increased number of abnormal ENG recordings in tinnitus patients so the aim of this study was to compare the ENG outcome with their neuropsychological status. The study was carried on 69 subjects […]
