Sex Differences in Presentation and Surgical Outcomes From a Prospective Multicenter Chronic Rhinosinusitis Study.

OBJECTIVE

Despite extensive research into chronic rhinosinusitis (CRS) epidemiology, presentation, and outcomes, there is scant knowledge on sex-specific differences. The objective of this study was to identify differences between male and female patients with CRS in baseline disease severity at presentation, choice for surgery vs continued medical treatment, and postoperative response.

STUDY

DESIGN

We evaluated data on demographic and health characteristics, clinical objective disease measures, and sinus-specific and general health patient-reported outcome measures.

SETTING

Secondary analysis of prospective multicenter outcome study.

METHODS

Comparison of cohort characteristics and baseline and postoperative measures was performed with a t test, chi-square test of independence, or Fisher exact test. Within-subject improvement was compared between sexes with a linear mixed model.

RESULTS

Females reported worse quality of life on presentation and postsurgery, despite experiencing less severe disease by standard clinical measures. Overall, females and males showed similar within-subject improvement after surgery. However, certain quality of life domains and disease measures showed sex-specific improvement. Females demonstrated greater within-subject improvement in SF6D-derived health utility and the SNOT-22 ear and facial, psychological, and sleep subdomains, although this did not reach statistical significance for the overall cohort.

CONCLUSION

Incorporating data on sex-specific differences may be important to personalize CRS treatment decision making. The discordance between patient-reported and clinical measures in CRS has been demonstrated in other pathologies and appears to be exaggerated by sex. Biological and psychological bases for sex-specific differences in CRS manifestations are an intriguing topic for further research.
