Background: Aside from the obvious negative effects on patients' and society's financial well-being, chronic rhinosinusitis (CRS) can lead to absenteeism, decreased productivity, and impaired respiratory function, all of which have a major influence on patients' and society's overall quality of life. Endoscopic sinus surgery is an option for patients who have not responded to other treatments, and there are several objective and subjective ways to evaluate the success of the procedure, even if there is little level 1 evidence. We summarize the available outcome metrics and provide a thorough evaluation of the published results up to this point. Also covered is research suggesting that endoscopic sinus surgery may improve asthma patients' respiratory performance.

Conclusion: There has been a shift in the last 20 years toward using patient-reported outcomes rather than objective data as the main result in sinus disease, especially CRS. The variety of instruments at our disposal enables us for assessment of the efficacy of surgery in relation to health-specific and general quality-of-life, burden of illness, healthcare utilization, and pulmonary function.
