This study evaluates the efficacy of politzeration on eustachian tube dysfunction following airplane travel using an automated, hand-held device that controls the volume velocity of air flow. Fourteen adults with eustachian tube dysfunction following airplane travel comprised the experimental group. They received politzeration over a period of 6 weeks on a twice-a-week basis. Fourteen adults wi...

The middle ear pressure variation is one of the most important factors that causes discomfort on flight passengers and crew. The purpose of this work is to develop a mathematical model of the middle ear cavity pressure variation during typical flight’s conditions. The middle ear cavity was modeled as a gas chamber that transfer gas to other physiological systems trough three different ways. One...

OBJECTIVES/HYPOTHESIS While continuous positive airway pressure (CPAP) is commonly used for obstructive sleep apnea treatment, its effect on middle ear pressure is unknown. The purpose of this study was to measure the effect of CPAP on middle ear pressure and describe the correlation between CPAP levels and middle ear pressures. STUDY DESIGN Retrospective review of normal tympanometry values ...

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...
