Objective: Odontogenic sinusitis (OS) is a well-known and important border of specialties
in otorhinolaryngology and dentoalveolar surgery. Odontogenic sinusitis can develop
due to iatrogenic harm or odontogenic infection. The gold standard diagnostic method
is clinical and radiological—CBCT (cone beam computed tomography)—examination. The
treatment of this condition requires collaboration between ENT and dentoalveolar surgery
specialists and can be non-surgical or surgical based on staging. This paper aims
to share the results of our clinical study whereby complex therapy was administered
by a dentoalveolar surgeon and an otorhinolaryngologist in cooperation. Patients and
methods: We conducted a retrospective study 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. Conclusions: 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.
