Otologic tests

Programming of the speech-processors in children provided with Cochlear Implant causes sometimes problems, especially in very small children. This becomes important at this time as the implantation-age of the children decreases continuously. With Neural Response Telemetry (NRT) stands for the Nucleus ® 24 Cochlear Implant system a new principle of programming of the speech processor […]

Modulation of tinnitus by a variety of somatosensory stimuli and alteration of gaze has been described. We present two cases of tinnitus induced by speech (voice). The tinnitus was troublesome in both patients, and both had hearing loss and ischemic changes in the central nervous system documented by magnetic resonance imaging. We discuss cross-modal plasticity […]

Tinnitus is a symptom that affects a great number of patients. Its diagnosis, treatment, and follow-up are difficult, owing to its subjectivity. The authors propose the use of distortion product otoacoustic emissions (DPOAEs) in tinnitus evaluation. They studied three groups: controls, having no complaint of tinnitus and normal hearing; group 1, presenting tinnitus and normal […]

Automatic ABR was introduced into Japan in 1997, and Universal Newborn Hearing Screening of a newborn infant term was enabled. The model research study of hearing screening in Japan was started 2001, and Saitama Prefecture was started the inspection research from October 2002. Many newborn babies started received hearing screening from 1999 in our medical […]

Glycerol test is still the most popular non-invasive specific test in Meniere’s disease. There are too few reports in literature regarding dynamics of the hearing level alteration in the course of the glycerol test. PURPOSE – to follow up dynamics of pure tone threshold alteration induced by glycerol in patients with defined Meniere’s disease, suspected […]

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 […]

The tinnitus can be functionally measured and localized through sensorymotor and neurosensorial tests, then there arises a great demand for a systematic pharmacological treatment. These tests indicate the numerous and different locations of the symptom, and enable us to prove that in around 24% of the patients, tinnitus has a peripheral origin, in 35% it […]

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 […]
