OBJECTIVES The objective of this study was to analyze a new technique, CO2 laser-assisted posterior semicircular canal ablation (LAPSCCA), in the treatment of refractory benign paroxysmal positional vertigo. STUDY DESIGN Prospective study of patients with disabling BPPV who failed conservative therapy. METHODS Patients noted to have been treated with at least three Epley maneuvers without s...

Objective: To describe the alterations observed in electronystagmography (ENG) of patients with spinocerebellar ataxia (SCA) types 2 and 3. Method: Sixteen patients were studied and the following procedures were carried out: anamnesis, otorhinolaryngological and vestibular evaluations. Results: The clinical findings in the entire group of patients were: gait disturbances (93.75%), dysarthria (4...

We analyse the neurootological data of patients attended in the Ear, Nose and Throat (E.N.T.) department of the Centro Hospitalar de Vila Nova de Gaia for a tinnitus problem. We submitted these patients to our neurootological routine evaluation. This approach is justified in a tinnitus patient because the cochleovestibular system is a unit and acts as a whole. We characterise the population tha...

The analysis of optokinetic nystagmus (OKN) provides valuable information about the condition of human vision system. One of the phenomena that is used in the medical diagnosis is optokinetic nystagmus. Nystagmus are voluntary or involuntarily eye movements being a response to a stimuli which activate the optokinetic systems. The electronystagmography (ENG) signal corresponding to the nystagmus...

The origin of the generation of saccadic and smooth-pursuit eye movements has not been proved. The goal of the study reported here was to search for the connection of visuooculomotor reactions--saccades and eye-tracking test--with cerebellar damage. Using electronystagmography, we tested 11 patients treated with aminoglycosides because of pneumonia. After a mean of 21 days of pharmacological th...

Tinnitus, a common symptom encountered in family medicine, is defined as the perception of noise in the absence of an acoustic stimulus outside of the body. Because tinnitus is a symptom and not a disease, its underlying cause must be determined to best help patients. Although tinnitus is often idiopathic, sensorineural hearing loss is the most common identified cause. It can also be caused by ...

This multisite investigation assessed subjective, behavioral, and objective balance function in 30 blast survivors. Subjects with vertigo, dizziness, or imbalance were screened (n = 6) or evaluated (n = 27) during 1 year. Tests included a questionnaire, electronystagmography (ENG), and computerized dynamic posturography (CDP). Ninety-seven percent of subjects were located inside a building duri...

The value of electronystagmography (ENG) and of tonography in monitoring the beneficial effect of edrophonium chloride (Tensilon) on the extraocular muscles in myasthenia gravis has been assessed. Studies were performed on 17 patients with myasthenia gravis and on 18 control subjects, of whom nine had extraocular muscle weakness due to myopathic or neurogenic lesions.Electronystagmography recor...
