Predictive factors in patients undergoing endoscopic sinus surgery for odontogenic sinusitis

Area of Science:

• Otolaryngology
• Dental Medicine
• Rhinology

Background:

• Odontogenic sinusitis (OS) poses a treatment challenge, with uncertainty regarding the necessity of dental treatment versus endoscopic sinus surgery (ESS).
• Identifying predictors for ESS in OS patients is crucial for effective management.

Purpose of the Study:

• To identify predictors of OS patients who ultimately require ESS.
• To determine factors influencing the need for surgical intervention in OS.

Main Methods:

• Retrospective review of 43 OS patients.
• Analysis of clinical factors, dental history, and Lund-Mackay scores (LMSs).
• Statistical analysis including logistic regression.

Main Results:

• 48% of OS patients required ESS after failing conservative treatment.
• Higher total LMS was observed in patients undergoing ESS (8.3 vs 3.7).
• Significant predictors for ESS were odontomaxillary complex (OMC) involvement (OR 37.3) and prior dental procedures (OR 7.4).
• All patients with oral-antral fistula (OAF) or retained dental hardware required ESS.

Conclusions:

• Nearly half of OS patients necessitate ESS for symptom control and complication prevention.
• Prior dental procedures and OMC involvement are key indicators for requiring ESS in OS patients.
