Background: Odontogenic sinusitis (ODS) is distinct from non-odontogenic rhinosinusitis, and often requires multidisciplinary collaboration between otolaryngologists and dental providers to make the diagnosis. The purpose of this study was to develop international multidisciplinary consensus on diagnosing ODS. Methods: A modified Delphi method was used to assess for expert consensus on diagnosing bacterial ODS. A multidisciplinary panel of 17 authors with ODS expertise from 8 countries (8 otolaryngologists, 9 dental specialists) was assembled. Each author completed 2 of 3 surveys (2 specialty-specific, and 1 for all authors). Thirty-seven clinical statements were created, focusing on 4 important diagnostic components: suspecting ODS; confirming sinusitis in ODS; confirming different dental pathologies causing ODS; and multidisciplinary collaborative aspects of diagnosing ODS. Target audiences were all otolaryngologists and dental providers. Results: Of the 37 clinical statements, 36 reached consensus or strong consensus, and 1 reached no consensus. Strong consensus was reached that certain clinical and microbiologic features should arouse suspicion for ODS, and that multidisciplinary collaboration between otolaryngologists and dental providers is generally required to diagnose ODS. To diagnose ODS, otolaryngologists should confirm sinusitis mainly based on nasal endoscopic findings of middle meatal purulence, edema, or polyps, and dental providers should confirm dental pathology based on clinical examination and dental imaging. Conclusion: Based on multidisciplinary international consensus, diagnosing ODS generally requires otolaryngologists to confirm sinusitis, and dental providers to confirm maxillary odontogenic pathology. Importantly, both dental providers and otolaryngologists should suspect ODS based on certain clinical features, and refer patients to appropriate providers for disease confirmation.
