Official title

Refractory Eustachian Tube Dysfunction: Are the Symptoms Related to Endolymphatic Hydrops?

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
