RESUMO
KEY POINTS: ETD symptoms are present in 16% patients with underlying skull base pathology. Preoperative ETD symptoms improve following surgical treatment of skull base pathology. ETD symptoms may worsen in patients with central, posterior, or malignant skull base pathology.

OBJECTIVES: To investigate how eustachian tube dysfunction symptoms change following surgical treatment of nonsinusitis-related nasal obstruction. STUDY DESIGN: Retrospective chart review. SETTING: Single academic center. METHODS: We assessed patients who underwent septoplasty, turbinate reduction, or both for nasal obstruction. Chronic sinusitis patients were excluded. Eustachian tube dysfunction (ETD) symptoms were studied using the Eustachian Tube Dysfunction Questionnaire (ETDQ-7), collected preoperatively and postoperatively (1 week, 1 month, 3 months, 6 months postop). Patients with preoperative ETDQ-7 > 14.5 were considered to have clinically significant symptoms. Sinonasal outcomes test scores were also assessed. Pre- and postoperative ETDQ-7 scores were compared using t test. Multivariate linear regression analysis identified factors associated with ETDQ-7 change. RESULTS: We analyzed 259 patients. Preoperatively, 37.5% of patients with nasal obstruction had clinically significant ETD symptoms. These patients exhibited significant improvement in ETDQ-7 at all postoperative timepoints from 23.3 ± 7.6 at baseline to 19.1 ± 9.1 at 1 week, 16.5 ± 8.0 at 1 month, 16.2 ± 7.8 at 3 months, and 16.7 ± 10.4 at 6 months (all P < .01). In patients without baseline ETD symptoms, (baseline ETDQ-7: 9.1 ± 2.3) ETDQ-7 scores did not change significantly at postoperative timepoints, except for an acute worsening at 1 week postoperatively (10.7 ± 5.1, P < .001). Regression analysis showed that higher preoperative ETDQ-7 score (ß = -0.84, 95% confidence interval [CI]: -1.10 to -0.59) and postoperative antihistamine spray usage (ß = -8.70, 95% CI: -14.20 to -3.20) were associated with ETDQ-7 improvement, while comorbid GERD (ß = 7.50, 95% CI: 3.42-11.58) and asthma (ß = 5.62, 95% CI: 0.80-10.45) were negatively associated with improvement. CONCLUSION: Surgical correction of nasal obstruction may improve ETD symptoms.
