Surgical and Dental Management of Odontogenic Sinusitis: A Retrospective Study

Odontogenic sinusitis is a recognized but understudied form of sinusitis that needs an individualized treatment regimen, different from non-odontogenic sinusitis. The aim of this study was to present and discuss our multidisciplinary management of odontogenic sinusitis. A single-center retrospective observational study was conducted in a cohort of patients who received diagnosis of odontogenic sinusitis between January 1st 2016 and 31st December 2023. The following data of the included patients were collected: age, gender, smoke history, symptoms, involved sites, anatomic location, etiology, performed surgical treatment, and performed dental treatment. A total of 41 cases of odontogenic sinusitis were reviewed. The most frequently reported symptoms were pain, rhinorrhea, and nasal obstruction. Oroantral fistula was the most frequent cause of odontogenic sinusitis, followed by odontogenic cysts, and dental implant migrated to the maxillary sinuses. The most frequently performed sinus treatment was intraoral approach combined with dental treatment/removal, followed by ESS combined with dental treatment/removal, and ESS alone. The most frequently performed dental treatment option was endodontic treatment, followed by dental extraction. Multidisciplinary and coordinated treatment is crucial to grant the best success opportunities, as independent rhinological or dental management alone often does not obtain a complete resolution of odontogenic sinusitis. Nevertheless, the ideal sequence and timing of management is still controversial and should be decided on a case-by-case criteria.
