Types E very acoustical system has an underlying level of noise. High-fidelity buffs refer to the signalto-noise ratio. The human auditory (acoustic) system is no exception. Other normal physiological noises include the sound of the pulse in the inner ear, the opening of the eustachian tube, the noise of respiration , and the like. Pathological tinnitus, on the other hand, is noise associated w...

A fairly quite rare case of osseous tumor arising from the Eustachian tube (ET) is described. A 56-year-old man presented with a smooth bulky mass in the nasopharynx and secretory otitis media in the right ear. Computed tomography and magnetic resonance imaging indicated a solid tumor-like region occupying the nasopharynx with apparent extension to the right ET. Transnasal endoscopic surgery de...

Although it has been reported that smoking has deleterious effects on the middle ears of smokers, including their eustachian tubes, investigators have failed to find differences in the tympanometric characteristics of smokers and nonsmokers. In the present study, however, we found that the Valsalva-induced tympanometric peak pressure shifts of young smokers were less than those measured among y...

BACKGROUND The Health Technology Assessment programme commissioned a wide-ranging review of treatments for adult Eustachian tube dysfunction. Treatments range from advice and observation and pharmacological treatments to surgical options. OBJECTIVE (i) To assess the evidence for interventions for adults with a clinical diagnosis of Eustachian tube dysfunction and (ii) to identify priorities f...
