Nasal Dilator Therapy for Patulous Eustachian Tube Dysfunction

25 de agosto de 2026 actualizado por: Vrabec, Jeffrey M.D., The Methodist Hospital Research Institute

Prospective PI-Initiated Study of Nasal Dilator Therapy in Patulous Eustachian Tube Dysfunction

The Eustachian tube connects the middle ear to the back of the nose and throat, providing ventilation of the middle ear. People with a patulous Eustachian tube perceive the tube stays open continuously. This can make a person's own voice and breathing sound unusually loud in the ear and can cause a feeling of fullness or blocked hearing. There is currently no agreed-upon first treatment for these symptoms.

Some people with this condition notice their symptoms improve when they gently pull the cheek outward to widen the nasal passage. A nasal dilator is a small, soft device worn just inside the nostrils that does something similar by holding the nasal passage more open. Nasal dilators are sold over the counter and are commonly used for stuffy nose and snoring. They have not been studied as a treatment for patulous Eustachian tube.

This study will look at whether wearing a nasal dilator reduces symptoms in adults with patulous Eustachian tube. About 50 adults treated at Houston Methodist will take part. Everyone in the study receives the nasal dilator; there is no placebo or comparison group.

Participants complete a 10-question symptom survey before using the device, again 10 minutes after putting it in for the first time, and once more at a follow-up clinic visit about 3 to 4 weeks later. Between visits, participants wear the device at home and keep track of how often they use it. At the follow-up visit they also answer questions about whether the device was comfortable and easy to use, and whether they had any side effects. Participation lasts about 3 to 4 weeks.

Descripción general del estudio

Descripción detallada

This is a single-arm, prospective, pre/post pilot study of a commercially available internal nasal dilator (Airmax) in adults with clinically confirmed patulous Eustachian tube dysfunction and a positive Cottle maneuver. Symptom burden is measured with the Patulous Eustachian Tube Handicap Inventory-10 (PHI-10) at baseline, 10 minutes after first device application, and at a 3-4 week follow-up visit. The study is intended to generate effect-size estimates to inform the design of subsequent controlled trials. The device is over-the-counter, 510(k)-exempt, used without modification, and the study is exempt from IDE requirements under 21 CFR 812.2(c).

Grupo de participantes/brazo
Intervención / Tratamiento
Experimental: Internal Nasal Dilator
Participants receive a commercially available internal nasal dilator (Airmax) at the baseline clinic visit, along with sizing, fitting, and hygiene instruction from trained study staff. Participants apply the device during the visit and continue at-home use per the study wear schedule until the follow-up visit approximately 3 to 4 weeks later.
Single-patient-use, over-the-counter internal nasal dilator worn inside the nasal vestibule to laterally support the nasal valve and increase nasal cross-sectional area. Devices are supplied in sealed retail packaging without modification. Participants wear the device per the prescribed schedule from the baseline visit until the follow-up visit at 3 to 4 weeks.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Change in Patulous Eustachian Tube Handicap Inventory-10 (PHI-10) score
Periodo de tiempo: Baseline and 3 to 4 weeks
The PHI-10 is a 10-item validated patient-reported instrument measuring symptom burden in patulous Eustachian tube. Total scores range from 0 to 40, with lower scores indicating fewer symptoms. The outcome is the change in total score from baseline to the follow-up visit.
Baseline and 3 to 4 weeks

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Acute change in PHI-10 score after first device application
Periodo de tiempo: Baseline and 10 minutes after first application
Change in PHI-10 total score from baseline to 10 minutes (±5 minutes) after the participant first applies the nasal dilator, assessing immediate symptom response. Scores range 0 to 40; lower is better.
Baseline and 10 minutes after first application
Adherence to device wear
Periodo de tiempo: Baseline through 3 to 4 weeks
Self-reported average hours of device wear per day and percentage of prescribed days on which the device was worn, collected at the follow-up visit.
Baseline through 3 to 4 weeks
Device usability and acceptability
Periodo de tiempo: 3 to 4 weeks
Participant ratings of comfort, ease of use, and willingness to continue use, each scored on a 5-point Likert scale ranging from 1 to 5, with higher scores indicating greater acceptability.
3 to 4 weeks
Global Rating of Change
Periodo de tiempo: 3 to 4 weeks
Single-item participant-reported rating of overall change in symptoms since baseline, collected at the follow-up visit.
3 to 4 weeks
Number of participants with device-related adverse events
Periodo de tiempo: Baseline through 3 to 4 weeks
Count of participants experiencing device-related adverse events, including nasal irritation, pressure discomfort, and epistaxis. Assessed at first wear, at the follow-up visit, and by interim report between visits.
Baseline through 3 to 4 weeks
