Eustachian Tube Dysfunction | The Study of Eustachian Tube Dysfunction and Laryngopharyngeal Reflux

Eustachian Tube Dysfunction research study

What is the primary objective of this study?

The purpose of this study is to investigate the relationship between ear fullness, pressure, and/or pain and laryngopharyngeal reflux, in order to focus medical therapy and improve therapeutic outcomes in this patient population.

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:Omeprazole40mg, to be taken once daily by mouth, 30-60 minutes before meals, for at least 6 weeks

Drug:Ranitidine300mg, to be taken once daily by mouth, before bedtime, for at least 6 weeks

Drug:Pantoprazole40mg, to be taken twice daily by mouth, 30-60 minutes before meals, for at least 6 weeks. (Alternative intervention if participant cannot tolerate omeprazole, is on an anticoagulant medication, or if on medication contraindicated for omeprazole and ranitidine)

Procedure:24-Hour Diagnostic pH-Probe TestParticipants will undergo a routine clinical 24-hour diagnostic pH-probe test to assess quantitative measures for laryngopharyngeal reflux.

Procedure:LaryngoscopyParticipants will undergo routine clinical laryngoscopy to assess presence of laryngopharyngeal reflux.

Study Arms
