Eustachian Tube Dysfunction Not Responding to Medical Management
In obstructive eustachian tube dysfunction (OETD), addressing identifiable underlying causes through medical management is the established first step. When that approach does not yield symptomatic improvement, a structured next-line intervention is warranted.
Previous Treatment & Failure Condition
Medical management of identified treatable causes
Medical management directed at allergic rhinitis, rhinosinusitis, and laryngopharyngeal reflux is the required prior step before procedural intervention. This protocol applies when symptomatic improvement of obstructive ETD has not been achieved through that approach.
Next-Line Approach (Partial Overview)
When OETD persists despite appropriate medical management of treatable causes — or when no such treatable cause is identified — a procedural intervention directed at the eustachian tube itself is indicated. An alternative tube-based procedure is also available. The complete decision criteria, candidate selection, and step-by-step protocol are in the full regimen.
Treatment Goals at 6 Weeks
- Normalisation of tympanograms and ETDQ-7 scores
- Ability to perform a modified Valsalva maneuver
- Improvement in patient-reported symptom scores

- A working definition of BDET was determined to be "inserting a catheter with a balloon temporarily into the cartilaginous portion of the ET and then inflating the balloon to alleviate obstructive ETD."
- BDET is appropriate in patients with obstructive ETD who have failed medical therapy for identified treatable causes.
- There is no direct medical treatment for isolated OETD, and BDET is appropriate when OETD is present in isolation or remains following appropriate medical management of potential confounding/coexisting conditions as listed above.
- BDET is an alternative to tympanostomy tube placement for obstructive ETD.
- After 6 weeks, a significantly greater number of BDET patients demonstrated normalization of tympanograms and ETDQ-7 scores (2.1) vs controls (51.8% vs 13.9%, P < .001; 56.2% vs 8.5%, P < .001).
- The panel reached consensus that the ability to perform a modified Valsalva maneuver is appropriate for assessing outcome after BDET.
- Change in patient-reported symptom scores is appropriate for assessing outcome following BDET.
