1. Middle ear structure in relation to function : the rat in middle ear research
Abstract : The present study was undertaken to evaluate the rat as a model for middle ear research. The rat was chosen primarily because the gross structure of its middle ear shows several similarities to that of man. READ MORE

2. On Pressure Regulation of the Middle Ear
Abstract : The middle ear (ME) pressure is regulated by gas diffusion over the ME mucosa and pressure equalizations via the Eustachian tube (ET). Disturbance in the regulation of ME pressure is believed to contribute to the development of chronic ear diseases. READ MORE

3. Influence of middle ear pressure changes on labyrinthine hydrodynamics and hearing physiology
Abstract : Results from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. READ MORE

4. Long-term follow-up after otitis media in childhood
Abstract : Objective: Most preschool children have suffered from at least one episode of acute otitis media (AOM) and/or secretory otitis media (SOM). Some children have frequent AOM episodes and/or prolonged and recurrent episodes of secretory otitis media (SOM). The long-term out-come and sequelae are not fully clarified. READ MORE

5. Middle Ear Pressure; A New Method for Continuous Direct Measurements
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
