Sensology

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 […]

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 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 […]

About 15% of temporal bone fractures are produced by blows to the occiput. The fracture line begins in the posterior fossa, at or near the foramen magnum, crosses the petrous ridge through the internal auditory canal and/or the otic capsule. Therefore it is thus called a transverse fracture. In transverse fractures of temporal bone, due […]

The auditory system has been the subject on studies of its capability to develop plastic responses to different kinds of lesions. Regeneration has been observed in the peripheral portions of the system, with neogenesis of hair cells in avians, sometimes followed by functional rehabilitation, with electrophysiological confirmation. It has been also noticed the ocurrence of […]

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 study attempted to determine those factors important for predicting the experienced severity of tinnitus. For this purpose, we examined affected patients’ perception of tinnitus as an illness, comorbidity, scores on locus of control, length of time since onset of tinnitus, pitch and loudness of tinnitus sounds, and depression. One hundred and forty-nine patients (72 […]

Diabetes mellitus is a chronic syndrome of impaired carbohydrate, protein, and fat metabolism secondary to insufficient secretion of insulin or to target tissue insulin resistance. The most common and most overlooked cause of vertigo is the impairment of carbohydrate metabolism. It is important that the patient with vertigo must be investigated from a metabolic point […]
