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.
In this study, patients with dysfunction of the eustachian tube will be included. They will be randomized to one of two treatment groups.~balloon dilation of the eustachian tube or~nasal saline Patients will undergo follow-up for one year and will be able to crossover to the treatment arm after three months
