1. Middle ear structure in relation to function : the rat in middle ear research
Sammanfattning : 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. LÄS MER
2. Influence of middle ear pressure changes on labyrinthine hydrodynamics and hearing physiology
Sammanfattning : 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. LÄS MER
3. Long-term follow-up after otitis media in childhood
Sammanfattning : 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. LÄS MER
4. Middle Ear Pressure; A New Method for Continuous Direct Measurements
Sammanfattning : 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. LÄS MER
5. Transmyringeal middle ear ventilation : an experimental approach to evaluation of its benefits and consequences
Sammanfattning : 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. LÄS MER
