    Abstract : Disturbances in the pressure homeostasis of the middle ear (ME) system cause a pressure gradient across the tympanic membrane lessen the effectiveness of sound transmission and may be associated to development of chronic ME disease. An equipment for continuous direct pressure measurements was developed and was found to be accurate, base-line stabile and portable. READ MORE

  3. 3. Transmyringeal middle ear ventilation an experimental approach to evaluation of its benefits and consequences

    Abstract : A prerequisite for a functioning middle ear is an air-filled middle ear cavity. Aeration of the middle ear cavity is controlled by the Eustachian tube. Dysfunction of the Eustachian tube has long been acknowledged as a significant etiological factor in disorders of the middle ear, especially middle ear effusions. READ MORE

  4. 4. The middle ear The inflammatory response in children with otitis media with effusion and the impact of atopy : clinical and histochemical studies

    Abstract : Although middle-ear cholesteatoma is a major topic in otological research, its etiology and pathogenesis remain unclear. Pediatric cholesteatoma is considered more aggressive than adult cholesteatoma, as it has a higher rate of growth, is more often infected and exhibits wider extension. READ MORE
