%X <B>BACKGROUND: </B>Subtypes of sinusitis have different symptoms and prognoses due to different pathogens. Odontogenic maxillary sinusitis (OMS) mainly occurs unilaterally and is different from chronic rhinosinusitis (CRS) usually occurring bilaterally in terms of clinical characteristics. However, comprehensive microbiological comparisons between OMS and CRS have never been systematically conducted and most comparisons are methodologically biased. This study aims to provide a comprehensive analysis of the microbiology associated with OMS and CRS through a meta-analysis approach in order to provide evidence for differential diagnosis of OMS and CRS from a microbiological perspective.<BR><B>METHODS: </B>The databases PubMed and CNKI were searched from their inception to July 2023. A random-effects model was employed to derive the pooled prevalence estimates of the identified bacterial species or genera.<BR><B>RESULTS: </B>The 17 represented studies included 6 concerning OMS, 12 concerning CRS, and 4 concerning normal sinus, yielding 191, 610, and 92 samples, respectively. Though not statistically significant, the prevalence of Peptostreptococcus and Prevotella was generally higher in OMS compared to CRS. Notably, Fusobacterium was identified as the only genus with a significantly higher prevalence in OMS compared to CRS.<BR><B>CONCLUSIONS: </B>Fusobacterium was significantly more prevalent in OMS compared with CRS, while Staphylococcus aureus was more prevalent in CRS than in OMS. Such differences in bacterial profile may partly explain the distinct pathology observed and contribute to the development of novel strategies for diagnosis and therapeutic interventions in OMS.
