35 patients with unilateral sensorineural impairment and hearing levels within the normal range in the opposite ears were investigated by bilateral transtympanic electrocochleography (TIECoG). Only 19 patients (54%) satisfied the criteria for Meniere's disease and 16 patients (46%) showed sensorineural impairment due to other etiologies. Clinical studies have focused exclusively on the a mp...

Due to the physics of magnetic fields and forces, any single magnet will always attract or pull-in magnetically-responsive particles. However, there are a variety of clinical needs where it is advantageous to be able to push away or ‘magnetically inject’ therapeutic particles. Here we focus on magnetic injection to treat inner-ear diseases. The inner ear is behind the blood-ear barrier, meaning...

objective(s) the aim of this study was to investigate the overall effect of cardiac vasoactive factors during coronary occlusion and reperfusion on peripheral vascular tone, using a sequential isolated rabbit heart-ear perfusion model. materials and methods isolated ears were perfused with the effluent of isolated hearts subjected to ischemia (30 min) and reperfusion (180 min, n=6). the compara...

Background and Objectives Wideband tympanometry (WBT) provides information additional to what can be provided by the relms of traditional tympanometry, such as absorbance, resonance frequency, peak pressure. We investigated characteristics WBT in various middle ear disorders, especially for chronic otitis media (COM), otosclerosis, patulous eustachian-tube disorder (ETD). Subjects Method recrui...

Using intravital fluorescence microscopy in the ears of hairless mice, we determined skin microvascular adaptations during the process of aging from juvenile to adult and senescent life (6-78 wk). Despite an increase of ear area within the first 36 wk, the number and branching pattern of both arteriolar and venular microvessels remained constant during the whole life period. Both arterioles and...
