In-office Eustachian Tube Dilation Reduces Symptoms Among Patients With Barometric Challenges

Balloon dilation of the eustachian tube has gained ground in the treatment of chronic dysfunction. A new indication for a larger group of patients has emerged, which is characterized by barochallenge only, which affects even more patients. Given the recent validation of the balloon dilation, we set out to explore if this procedure could be useful in treating this specific sub-group of patients in an in-office setting.

Balloon dilation was performed using inly nasal cottonoids soaked in 2% tretracainephenylephrine combined with xylocaine nasal spray and lidocaine/prilocaine gel and a mild oral sedative. The effect of eustachian tube balloon dilation on the function of the eustachian tube was evaluated by using the eustachian tube dysfunction questionnaire-7 (ETDQ-7) and a VAS score. The questionnaires were completed beforehand and 3 months and 12 months postoperatively to determine subjective surgical success.

Two hundred and forty-six balloon dilation were performed in 132 participants. The results from the ETDQ-7 questionnaire and VAS scores showed a significant improvement in symptoms during pressurization after eustachian tube balloon dilation (p = 0.0001). A mean pain score during procedure in local anesthesia was 3.4 on a scale from 1 to 10.

Eustachian tube balloon dilation significantly reduced symptoms of eustachian tube dysfunction during non-physiological pressure, which was determined by ETDQ-7 and Vas scores. Additionally, we found that the procedure is well suited for private practice or the outpatient clinic, using local anesthetics and a mild sedative.
