Comparison of bacterial maxillary sinus cultures between odontogenic sinusitis and chronic rhinosinusitis
ConclusionCertain bacteria were more likely to be associated with ODS compared to CRS when purulence was cultured from the maxillary sinus. Physicians should evaluate for an odontogenic source of sinusitis when these ODS ‐associated bacteria are identified in maxillary sinus cultures.

Mapping and comparing bacterial microbiota in the sinonasal cavity of healthy, allergic rhinitis, and chronic rhinosinusitis subjects
ConclusionThis study presents the sinonasal microbiome profile in one of the larger populations of non‐CRS and CRS subjects, and is the first office‐based cohort in the literature. In contrast to healthy, AR, and CRSwNP subjects, CRSsNP MM samples exhibited decreased microbiome diversity and anaerobic enrichment. CRSsNP MM samples had reduced diversity compared to same‐subject IM samples, a novel finding.
