Text of the abstract

Introduction: Odontogenic sinusitis (OS) is an important border of specialties between otorhinolaryngology and dentoalveolar surgery. OS is the inflammation of the maxillary sinus which develops through the violation of the Schneiderian membrane. According to most studies, odontogenic sinusitis accounts for 10–14% of all types of maxillary sinusitis, but the actual incidence can be even higher, some studies report a much higher incidence, at approximately 40%. The treatment of odontogenic sinusitis calls for a collaboration between otorhinolaryngologists, dentoalveolar surgeons and dentists. The aim of the therapy is to eliminate the underlying cause, relieve symptoms and restore the normal function of the sinus. During treatment, the dental infection source and inflammation of the sinus cavity have to be eliminated as well.
Aims: Investigate the success rate of single step FESS (Functional Endoscopic Sinus Surgery) and dentoalveolar surgery treatment and collect anamnestic, demographic data about patients with OS.
Methods: We conducted a retrospective analysis comprising 111 OS patients who underwent complex therapy between 2016 and 2023 at Semmelweis University, Budapest, Hungary. All patients were treated with concurrent FESS (functional endoscopic sinus surgery) and dentoalveolar surgery. Follow-up was based on symptoms, clinical examination and CBCT imaging.
Results: Of the 111 patients, 107 were successfully treated with concurrent FESS and dentoalveolar surgery, and only 4 had further symptoms following the complex therapy and needed retreatment.
Conclusion: The complex, single-session therapy involving FESS and oral surgery is an effective treatment method, which is less invasive and associated with fewer complications compared to previous interventions, such as the Luc–Caldwell procedure.
