This study evaluates the use of the EarFlo device in adults with clinically confirmed Eustachian tube dysfunction and/or otitis media with effusion. The purpose of the study is to assess the safety, tolerability, and short-term effects of device use on ear pressure symptoms and middle ear function. Participants will complete a brief symptom questionnaire, undergo routine ear examinations and testing, and use the EarFlo device once during a clinic visit. Ear examination and testing will be repeated after device use to evaluate any short-term changes. This study involves a single study visit and does not include any surgical or invasive procedures.

Otitis media with effusion (OME) is a condition characterized by the presence of fluid in the middle ear and may occur in both children and adults. Eustachian tube dysfunction (ETD) is commonly associated with OME and may contribute to symptoms such as ear fullness, pressure, muffled hearing, and discomfort due to impaired ventilation of the middle ear. The EarFlo device is designed to promote Eustachian tube opening during swallowing. The EarFlo device has been previously evaluated in pediatric populations with otitis media with effusion and is FDA-cleared for its intended use.This study aims to evaluate the safety, tolerability, and short-term effects of the EarFlo device in an adult population diagnosed with OME and/or ETD. This is a prospective, single-visit, non-randomized interventional study evaluating the safety, tolerability, and short-term effects of the EarFlo device in adults with otitis media with effusion (OME) and/or Eustachian tube dysfunction (ETD). The study focuses on short-term changes in subjective symptoms and objective middle ear findings following a single supervised use of the device in a clinical setting. Eligible participants will attend one study visit. At baseline, participants will complete a validated symptom questionnaire and undergo routine otologic evaluation, including otoscopic examination and tympanometry, as clinically appropriate. Otoscopic images of the tympanic membrane and middle ear will be captured prior to device use. Participants will then receive instruction on proper use of the EarFlo device from trained study personnel. The device will be used once during the visit while the participant drinks a liquid of their choice. Device use is noninvasive and does not involve surgical procedures or sedation. Following device use, participants will repeat middle ear assessments, including tympanometry and otoscopic examination. Post-use otoscopic images will be captured and compared with baseline images. Otoscopic images will be reviewed and categorized as improved or not improved by a physician who is blinded to the timing of image acquisition (pre- or post-device use). The primary objectives of this study are to evaluate the safety, tolerability, and short-term effects of the EarFlo device in adults and to obtain preliminary estimates of its short-term effects on ear pressure symptoms and middle ear findings following a single supervised use. As a single-arm pilot study, the findings are intended to inform the design of future controlled studies. No long-term follow-up is required.
