Background: Eustachian tube dysfunction is a common medical condition affecting approximately 1% of the adult population. Previous studies have evaluated eustachian balloon tuboplasty using tympanometry, ability to perform Valsalva maneuver and subjective improvement in symptoms to measure effectiveness. In this study, we propose using the Sino-Nasal Outcome Test (SNOT-22) to measure outcomes following eustachian tube balloon dilation, with a focus on ear-specific symptoms within the survey. Objective: To evaluate ear-specific symptom outcomes following eustachian tube balloon dilation using the SNOT-22 questionnaire. Methods: A retrospective chart review was performed on all patients who underwent eustachian tube balloon dilation from February 2015 to June 2017. Patients who completed the SNOT-22 survey before and after undergoing elective eustachian tube balloon were included. The mean difference of total scores as well as ear-specific symptom scores were compared. Paired T-tests were performed to evaluate whether there was a significant improvement in symptoms. Ear-specific scores included ear fullness/popping, ear pain, and dizziness. Results: 17 patients completed pre-operative and postoperative SNOT-22 questionnaire. The mean pre-operative ear-specific SNOT-22 symptom score was 6.94. The postoperative score was 3.47, with a mean difference of 3.47 (95%CI: 1.05-5.89; p = 0.0032). The mean pre-operative total SNOT-22 score was 35, post-op score was 15.35 with a mean difference of 19.65, (95%CI: 8.33-30.97; p = 0.0006). Conclusion: Patients have significant improvement in SNOT-22 ear-specific symptom scores following eustachian tube balloon dilation.
