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 […]
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 […]
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.
In patients with hypertrophic cardiomyopathy (HCM) coexisting sensorineural hearing disorders are present frequently. These disorders can be either cochlear or retrocochlear in origin. Our aim was to study the hearing function in patients with HCM and to compare this group with age matched controls . Our audiological investigations were performed in 44 patients with HCM. […]
The results of the use of clarion implants in 30 Indian patients have been evaluated. Cases included in the study were prelingual & postlingual patients where the cochlea was normal and prelingual patients where the cochlea had a Mondini defect or was ossified. It was found that multiple speech strategies available with the Clarion implant […]
