Diagnosis (both required):
i. Persistent OETD symptoms assessed by Eustachian Tube Dysfunction Questionnaire (ETDQ-7) with overall score of ≥3 (moderate to severe symptoms) for 3 months or more prior to enrollment.
ii. Refractory to medical therapy (minimum of 4 weeks of daily intranasal steroid spray or one completed course of an oral steroid within 3 months before study enrollment).
Exclusion Criteria:

- Prior eustachian tube intervention
- Presence of myringotomy ventilation tube or a tympanic membrane perforation
- Active chronic or acute otitis media
- Chronic otitis media with cholesteatoma
- Fluctuating sensorineural hearing loss or Meniere's disease
- Chronic rhinosinusitis, allergies, or reflux disease not controlled with medication
- History of head or neck surgery within 3 months
- Prior radiation to the head and neck
- Active temporomandibular joint disorders
- Cleft palate or Craniofacial syndrome
- Cystic fibrosis or Ciliary dysmotility syndrome or Systemic immunodeficiencies
- Active acute upper respiratory infection
- Nasal endoscopy with evidence of anatomic conditions that would prevent transnasal access to the Eustachian tube
- CT temporal bone scan with evidence of carotid artery dehiscence, superior semicircular canal dehiscence, or extrinsic eustachian tube compression
- Patient unable to follow protocol for any reason

5. Study Description
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.
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
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.
