Sex and gender in rhinosinusitis: a review.

Rhinosinusitis is a highly prevalent, inflammatory condition affecting the nose and paranasal sinuses, impacting an individual's quality of life with significant health care burden. Sinusitis is more frequent in females, and they typically present with more severe symptoms and worse quality of life scores. Males are more likely to present with nasal polyps and have higher objective scores on imaging studies. Differences in sinus microbiota by sex may play a role in understanding differences in clinical presentations between them, but additional research is required. An improved understanding of sex and gender-based differences in pathophysiology and clinical presentations will help to decrease inequities in accessing healthcare and optimizing long-term personalized patient outcomes.
