Sinonasal quality of life after endoscopic resection of malignant sinonasal and skull base tumors.

Objectives: Improvement in sinonasal quality of life (QoL) following sinus surgery has been well‐documented across the literature. To our knowledge, only one series has evaluated long‐term QoL in patients undergoing tumor resection, and that study demonstrated no improvement in rhinologic QoL following malignant tumor resection at 2‐year follow‐up. The objective of the present study was to evaluate QoL in the 2 years following endoscopic malignant tumor resection. Methods: A prospective cohort study was performed, including patients with both malignant and benign sinonasal tumors in a tertiary academic medical center. Patients undergoing endoscopic tumor resection who had completed Sinonasal Outcome Test 22 (SNOT‐22) questionnaires were included in the cohort. SNOT‐22 questionnaires were administered preoperatively and over a 2‐year follow‐up period at clinic visits. Longitudinal linear mixed‐effects regression was used to compare preoperative QoL to QoL over the 2 years following surgery. Results: Among 145 patients included in this study, 64 had malignant tumors. There was a statistically significant improvement in SNOT‐22 score from baseline to 2 years for patients with both malignant tumors (37.0, 95% confidence Interval [CI] 32.0–42.1 at baseline; 26.5 95% CI 20.8–32.2 at 2 years; <italic>P</italic> < 0.001) and benign tumors (26.5, 95% CI 21.4–30.4 at baseline; 12.9 95% CI 7.6–18.2 at 2 years; <italic>P</italic> < 0.001). Conclusion: In contrast to previously reported series, in this cohort endoscopic resection of sinonasal tumors appears to be followed by an improvement in QoL, which is sustained over a 2‐year period.
