Brief Summary

The Eustachian tube is a narrow tube which links the back of the nose to the middle ear. Eustachian tube dysfunction may occur when the mucosal lining of the tube is swollen, or does not open or close properly. It can occur after the start of a cold and other nose, sinus, ear and throat infections causing ear pain and pressure, fullness, cracking/popping sounds. This is an ubiquitous healthcare problem, affecting children and adults, that can lead to severe consequences including hearing loss, chronic otitis media, tinnitus, and vertigo. Numerous studies have consistently failed to support the effectiveness of medical managements. Pressure equalizing tubes are considered a temporary solution that does not treat the underlying pathology. More recent preliminary evidence of using inflation of a noncompressible balloon in the eustachian tube improved clinical outcomes, patients' symptoms and quality of life. This eustachian dilation catheter is not accessible in Canada since the device and procedure is not covered by OHIP (Ontario health insurance plan) or any other health insurance in Canada. In a cadaver study, we have evaluated using an endovascular balloon (Balloon that is used to dilate (expand) vessels) for eustachian tube dilation, which only costs about 10% of the eustachian tube dilation device. This endovascular balloon is Health Canada approved, but not for this specific use. We therefore want to conduct a pilot safety study with the main goal of assessing feasibility of eustachian tube dilation with the endovascular device.

You may qualify if:

  • ≥18 years old (of both sexes)

  • 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
  • Cleft palate or Craniofacial syndrome
  • Prior eustachian tube intervention
  • Prior radiation to the head and neck
