Study Summary
This research study measures how well the Eustachian tube works and looks directly at the anatomy of the Eustachian tube in adults who have had tympanostomy tubes surgically inserted into their eardrums because they have been diagnosed as having either "otitis media" or "poor Eustachian tube function". The Eustachian tube is a biologic tube that connects the back of the nose to the middle ear (the airspace located behind your eardrum). That tube is usually closed, but can be opened by swallowing and other activities. Periodic openings of the Eustachian tube allow air to flow between the nose and middle ear which keeps the pressure of gas in the middle ear at the same level as that of the atmosphere, a condition required for good hearing. In children and adults, middle-ear diseases such as otitis media with effusion (the buildup of fluid within the middle ear) and a form of temporary hearing loss (conductive hearing loss) occur if the Eustachian tube does not open, does not open frequently enough or is always open (called a patulous Eustachian tube). A diagnosis of these different conditions can be made using standard, clinical tests of Eustachian tube function and the Eustachian tube can be visualized where it enters the back of the nose using a specialized telescope called an endoscope. Some scientific reports suggest that the cause of poor Eustachian tube function in an individual can be determined by studying the anatomy of the Eustachian tube at the back of the nose and the movements of the Eustachian tube in that area during swallowing, talking and other activities using an endoscope. In this study, the investigators plan to explore the relationship between the results of the standard Eustachian tube function tests and those for the anatomy and function of the Eustachian tube in adults with a disease condition likely to be caused by poor Eustachian tube function. Also, there are a number other disease conditions (examples: nasal allergy, acid reflux disease) t
