Eustachian tube balloon dilation catheter
Small balloon catheter inserted transnasally/endoscopically into the cartilaginous Eustachian tube; distinct, despite the similar balloon-catheter technology, from the already-catalogued sinus balloon dilation device, which dilates a paranasal sinus ostium.
How it is used
Treatment of obstructive Eustachian tube dysfunction (chronic serous otitis media, barotrauma, failed tympanoplasty).
