BACKGROUND: The Eustachian Tube Dysfunction Questionnaire 7 (ETDQ-7) serves as a valuable tool for assessing eustachian tube dysfunction (ETD). We investigated the impact of septal deviation side on ETD using preoperative ETDQ-7 scores and evaluated the effectiveness of septoplasty based on postoperative ETDQ-7 scores. METHODOLOGY: We conducted a retrospective analysis of patients with septal deviation who were scheduled for septoplasty. ETDQ-7 surveys were conducted preoperative and 1 and 3 months postoperative. RESULTS: 120 patients were included, with 72 completing the ETDQ-7 at all three time points. The average prevalence of ETD was 29.2%. Preoperative ETDQ-7 scores showed no significant difference between convex and concave nasal sides. However, the prevalence of ETD was significantly higher on the convex side (28.3% vs. 15.8%), especially in unilateral ETD cases. Preoperatively, the positive ETD group had significantly higher ETDQ-7 scores on the convex side while no significant difference was found between concave and convex sides in the negative ETD group. Postoperatively, the positive ETD group showed significant improvement in ETDQ-7 scores with significantly higher on the convex side (66.7% vs. 33.3%). ETDQ-7 scores improved after septoplasty, with more improvement in the positive ETD group. CONCLUSIONS: Septoplasty significantly improves ETD, particularly in the preoperative positive ETD group, by reducing ETDQ-7 scores. The prevalence of ETD was higher on the convex side preoperatively, and the positive ETD group exhibited significant postoperative improvements, especially on the convex side. This suggests that the direction of septal deviation influences ETD prevalence and surgery outcomes, although septoplasty alleviates ETD on both sides.
