The rhinological manifestations of women's health.

OBJECTIVE

To systematically review the literature and appraise the evidence reporting the effects of women's health, including pregnancy, postpartum, menstruation, oral contraception, menopause, and hormone replacement therapy, on common rhinological pathologies and nasal physiology.

DATA SOURCES: Systematic search strategy using MEDLINE (1966-2012) and EMBASE (1980-2012) databases.

REVIEW

METHODS

Title review, abstract screening, and then full paper analysis were undertaken by 2 authors independently. Level of evidence was graded according to the Oxford Centre of Evidence Based Medicine 2011 criteria and risk of bias assessment using the Jadad scale for randomized controlled trials and Newcastle-Ottawa Scale for cohort and case-controlled studies.

RESULTS

Over the 46 years analyzed, the search strategy produced 2904 titles. In total, 314 abstracts were screened, from which 192 full-text articles were evaluated, and 145 research papers met all the criteria for inclusion in the study. Overall, the available evidence was of low quality. Seventy percent of studies (102 of 145) were case reports or case series from which only limited conclusions can be drawn. Only 3% of the included papers (4 of 145) were randomized controlled studies. The remaining data were mainly of a prospective cohort design. Study heterogeneity in design and measured outcomes resulted in data synthesis being limited to a descriptive/exploratory review. Study findings are presented by women's health category and then by rhinological manifestation with important clinical correlations highlighted.

CONCLUSION

Physiological and hormonal changes occurring as a normal part of women's health have an important influence on rhinological function and disease.
