Objectives
To prospectively evaluate the technical feasibility and safety of fluoroscopy-guided balloon dilation in patients with Eustachian tube (ET) dysfunction.
Methods
Patients who could not do a Valsalva manoeuvre for more than 6 months and diagnosed with chronic otitis media or ET dysfunction were prospectively enrolled. A 0.035-in. guide wire and 6-mm long balloon catheter with a diameter of 2 mm were used to dilate the cartilaginous portion of the ET under fluoroscopic guidance. The balloon was inflated by manual injection twice for 1 min each time. Clinical outcomes were assessed by the patient’s ability to perform a Valsalva manoeuvre, and symptoms were assessed using the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) score.
Results
Balloon dilation was attempted in a total of ten adult patients from October 2016 to March 2017. Technical success was achieved in all procedures (10/10). Ninety percent (9/10) of the balloons were fully dilated without waist deformity. There were no major complications. All patients were able to perform a Valsalva manoeuvre at the time of their last visit and/or improvement of at least one ETDQ-7 score.
Conclusion
Fluoroscopy-guided balloon dilation seems to be technically feasible and safe in the treatment of ET dysfunction.
Key points
• Fluoroscopy-guided balloon dilation without general anaesthesia was well-tolerated in all patients.
• Location of the balloon catheter can be monitored during the procedure.
• Inflation state of the balloon catheter can be monitored during the procedure.
• Using guide-wire during the procedure would prevent false passage creation.
• All patients had clinical improvement within 3 months after balloon dilation.
