Background:
Sufficient diagnostic tools and effective therapies for chronic obstructive eustachian tube dysfunction are lacking.
Patients And Methods:
A total of 120 patients (209 ears) with chronic obstructive eustachian tube dysfunction were treated over a 2-year period using transnasal endoscopic balloon dilatation of the cartilaginous part of the eustachian tube (balloon eustachian tuboplasty, BET). A balloon catheter is inserted into the eustachian tube via the pharyngeal opening and dilated with a pressure of 10 bar for 2 min.
Results:
The first 12 patients (20 dilatations) had a pretreatment average tube score of 1.25 (± 1.83 SD), and 1 year after treatment, the score improved to 6.2 (± 2.61 SD). Furthermore, the pretreatment and 2-month posttreatment data of 66 additional patients (115 dilatations) were analyzed. In these patients, the tube score improved significantly from 2.21 (± 2.02 SD) to 5.4 (± 2.53 SD).
Conclusion:
The initial long-term results suggest that BET is feasible and safe for the treatment of chronic obstructive eustachian tube dysfunction.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.
