Filter by:The purpose of this study is to evaluate the benefit of treatment of refractory Eustachian tube dysfunction with standard treatment for endolymphatic hydrops. Eustachian tube dysfunction is a common diagnosis made in otolaryngology related to abnormal pressure equalization of the middle ear space related to a swollen, inflamed, or occluded Eustachian tube. The symptoms of this include perceived hearing loss, a feeling of fullness in the affected ear/ears, ear pain, ear popping, and occasionally imbalance. These symptoms overlap with a more rare and difficult to diagnose condition known as endolymphatic hydrops, or an overproduction to fluid in the inner ear. The treatment for these two conditions are distinct and traditionally, patients are treated for Eustachian tube dysfunction first as it is much more common and there are several treatments, namely nasal steroids, antihistamines, and pressure equalization tubes. For patients who do not improve with these treatments, they are often treated with diuretics and a low salt diet to treat for supposed endolymphatic hydrops. There has never been a study to investigate the utility of these treatments in patients with refractory Eustachian tube dysfunction. There is also reason to believe that chronic ETD with effusion can lead to both inner and middle ear dysfunction. Thus, this study aims to determine the benefit of standard endolymphatic hydrops treatment on patient with refractory Eustachian tube dysfunction symptoms in a prospective fashion. Hypothesis: Patients with refractory Eustachian tube dysfunction (patients with no or minimal symptom improvement despite nasal steroid and antihistamine treatment followed by myringotomy tube placement) have an element of endolymphatic hydrops and these patient's symptoms will improve with a low sodium diet and diuretic.
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) that are related to poor Eustachian tube function and it is possible that these conditions and their effect on Eustachian tube function can be treated with medicines. Therefore, the investigators also plan to evaluate enrolled persons for those conditions. It is expected that if the results of the standard Eustachian tube function tests can be explained by the anatomy of the back of the nose and Eustachian tube, the functional anatomy (movements during swallowing etc) of the Eustachian tube or the presence of allergy and or/acid reflux disease, new medical and/or surgical treatments can be developed to improve Eustachian tube function and "cure" or treat the associated middle-ear diseases.
