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...

Mucins are important glycoproteins in the mucociliary transport system of the middle ear and Eustachian tube. Little is known about mucin expression within this system under physiological and pathological conditions. This study demonstrated the expression of MUC5B, MUC5AC, MUC4, and MUC1 in the human Eustachian tube, whereas only MUC5B mucin expression was demonstrated in noninflamed middle ear...

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...

IMPORTANCE Eustachian tube (ET) dysfunction predisposes ears to otitis media, tympanic membrane retraction, retraction pocket and perforation, or cholesteatoma. OBJECTIVE To develop a method to quantitatively measure the eustachian tube (ET) component movements and their interactions captured by transnasal videoendoscopy of the ET during swallowing. DESIGN, SETTING, AND PARTICIPANTS A blind...

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...
