Study Summary
This study will determine if gas can pass between the environment and the middle ear by way of the eardrum. This route of gas exchange was observed in animals but has not been studied in humans. If gas exchange across the eardrum is documented and the rate is sufficiently high, this can help explain certain past observations such as why middle ear pressure does not change very much in some children and adults when they have a cold or flu. The investigators also expect that the rate of gas exchange across the eardrum will depend on whether or not the eardrum has scarred or abnormally thin regions.
