Study Summary
The purpose of this study is to gather more information on Eustachian tube function and middle-ear pressures during flying. Ten subjects with tympanostomy tubes (plastic tubes inserted in the eardrums) in their ears or holes in their ear-drums will undergo flight simulation in a pressure chamber. Their middle-ear pressures and Eustachian tube function will be monitored at various chamber pressures.
Primary Outcome
middle-ear pressure will be monitored continuously during experiment
