CONCLUSION
In this first prospective cohort study on HRQoL after surgical removal of a sinonasal inverted papilloma, we observed a temporary decline in HRQoL shortly after the surgery, primarily attributed to the social limitations encountered by patients. In the total examined postoperative period, all three health domains, and consequently, the overall HRQoL improved significantly. Moreover, we found that a higher ASA score, a higher preoperative EES-Q score, and the administration of postoperative antibiotics were significant predictors for better HRQoL recovery postoperatively. Further research is necessary to confirm these results.
