Quantitative electroencephalography: preliminary report—tinnitus
This preliminary report is an account of 21 consecutive patients who had tinnitus of the severe disabling type and were examined with quantitative electroencephalography (QEEG).

Effects of noise on the intensity of distortion product otoacoustic emissions
Distortion product otoacoustic emission (DPOAE) is a widely used differential diagnostic method for diagnosing inner ear disorders. It provides us information on the condition of the outer hearing cells (OHCs).
Doppler ultrasonography in tinnitus patients
Tinnitus can be functionally measured and localized through sensorimotor and neurosensory tests. According to our Neurofisiología Otooftalmológica data bank, 60% of patients requiring a consultation have a history of cardiocirculatory disorders. This figure has moved us to study cerebrovascular processes in those patients seeking consultation for a tinnitus symptom only. The sudden appearance of the […]
Vertigo as a prognostic sign in sudden sensorineural hearing loss
Several prognostic indicators of favorable outcome in idiopathic sudden sensorineural hearing loss (ISSHL) have been proposed: an initial profound hearing loss, a down-sloping audiometric curve, advanced age, and the presence of vertigo. The latter has been disputed in the literature. The present study addressed the correlation between vertigo and outcome of ISSHL. Sixty-seven patients with […]
The alteration of hearing process in antiorthostatic position modelling microgravitation
The cranial shifting of body fluids developing in microgravity can be modelled by –300 head-down tilt body position (antiorthostatic posture) on Earth. Authors examined a group of 13 healthy voluntary young men in antiorthostatic posture and recorded the alteration of parameters in complex examinations. Among them pure tone threshold and speech threshold examinations were carried […]
