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. Middle ear mechanics : using temporal bone experiments to improve clinical methods
Sammanfattning : BackgroundThe middle ear transmits and amplifies sound vibrations from the tympanic membrane via three ossicles to the inner ear. Moreover, it contains two muscles, the stapedius muscle (SM) which protects the inner ear from loud noise, and the tensor tympani (TT) whose function is still debated. LÄS MER
3. Transmyringeal middle ear ventilation : an experimental approach to evaluation of its benefits and consequences
