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 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 […]
