Balloon Dilation of the Eustachian Tube
- Conditions
- Eustachian Tube Dysfunction
- Interventions
- Device: Balloon dilation of the eustachian tube
- Registration Number
- NCT05270031
- Lead Sponsor
- Sunnybrook Health Sciences Centre
- Brief Summary
In this study, patients with dysfunction of the eustachian tube will be included. They will be randomized to one of two treatment groups.
1. balloon dilation of the eustachian tube or
2. nasal saline Patients will undergo follow-up for one year and will be able to crossover to the treatment arm after three months
- Detailed Description
Patients will eustachian tube dysfunction will be asked to participate in the study.
They will be randomized to one of two groups
group 1 - surgical dilation of the eustachian tube in general anaesthesia
group 2 - daily nasal saline spray, twice a day
Regular Follow up with Tympanogram and Questionnaire
After three months patient in the control group (nasal saline) can switch in the intervention group.
Eustachian tube dilation will be carried out with a Health Canada and FDA approved device, usually used for endovascular balloon dilation. It has the same size and pressure properties as the eustachian tube dilation device and has shown a good safety profile in a previous preclinical and clinical pilot study.
