Classification of Odontogenic Sinusitis: A Clinical-Based Phenotyping System to Guide Multidisciplinary Surgical Management.

Background: Odontogenic sinusitis (ODS) is a condition that requires a multidisciplinary approach for successful treatment. Effective communication among the healthcare providers involved reduces the risk of errors and treatment failure. This study proposes a new ODS classification system to facilitate the communication of pivotal clinical information. Materials and Methods: In this observational study the authors considered 124 consecutive patients with ODS treated in the Campus Bio-Medico of Rome Foundation Hospital. The main elements influencing the treatment of this condition resulted as: timing, etiology, presence of foreign body, maxillary obstruction of the ostiomeatal complex, and presence of oroantral fistula (OAF); these elements were organized in the acronym TEBOF. Each patient received a TEBOF classification. The "T" was categorized in "T Results: Among the 124 patients included (64 women, 51.6%; mean age 57.2 ± 13 years), chronic sinusitis (T Conclusions: The TEBOF classification provides a concise, reproducible, and clinically intuitive tool for the characterization of odontogenic sinusitis. By integrating timing, etiology, and key anatomical features into a compact alphanumeric code, it facilitates multidisciplinary communication between otolaryngologists and dental providers, and may guide the selection of the most appropriate surgical strategy for each patient. Level of Evidence: 4.
