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 […]

The pathogenesis of sudden sensorineural hearing loss (SNHL) and tinnitus are still not well understood. Prompted by such observations, we implemented a protocol using sodium enoxaparin associated with a venovenous hemofiltration for treatment of sudden hearing loss and tinnitus. The venovenous hemofiltration selectively eliminates fibrinogen, low-density lipoprotein, cholesterol, triglycerides, lipoprotein and complement from the blood […]

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 […]

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 […]

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 […]

We prospectively studied 48 otosclerosis patients over a 2-year interval. Forty-four had stapedotomy, and four had stapedectomy. Demographics, clinical history, and pre- and postoperative audiometry results were recorded. A questionnaire asking about tinnitus (intensity, pitch) and including a visual analog scale quantifying the degree (1–10) of annoyance caused by the tinnitus was completed pre- and […]

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 […]

Tinnitus affects nearly 50 million people in the United States, with a minority demonstrating marked functional impairment. Alterations of gamma aminobutyric acid (GABA) neuronal function and benzodiazepine receptor (BZR) function in particular have been implicated in the pathophysiology of severe, chronic tinnitus. The purpose of our study was to evaluate the distribution of BZR in […]

The purpose of this study is to present the results of a pilot study of early detection of sensoneural hearing loss and early intervention to use music therapy, in order to demonstrate the applications of music therapy, and to measure systematically some of its effects on babies. Subjects for this study were 40 babies (22 […]

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 […]
