Abstract

Abstract : Background: Odontogenic sinusitis (OS) presents a therapeutic dilemma. Evidence is lacking whether dental treatment alone is sufficient or whether patients will eventually require endoscopic sinus surgery (ESS). Our aim was to identify predictors of OS patients undergoing ESS. Methods: Retrospective review performed of OS patients (n = 43) analyzing multiple factors including age, sex, symptoms, prior dental procedures, treatment, diabetes, immunosuppression, smoking history, retained dental hardware, oral‐antral fistula (OAF), and Lund‐Mackay scores (LMSs). Descriptive statistics, Wilcoxon rank sum, and logistic regression analyses were performed. Results: Common presenting symptoms included facial pressure, discolored nasal drainage, and foul smell/taste. Half of patients presented either after a recent dental procedure or with dental complaints. Forty‐eight percent required ESS after failing medical and dental therapy alone. Total LMS was significantly higher in the group undergoing ESS (8.3 vs 3.7; p = 0.0003). Multivariate analysis showed 2 significant predictors of undergoing ESS: (1) OMC involvement (OR 37.3, p = 0.003) and prior dental procedure (OR 7.4, p = 0.03). All patients with OAF or retained dental hardware required ESS. Conclusion: Forty‐eight percent of patients who presented with OS underwent ESS for symptom control and prevention of complications. Patients who underwent ESS had significantly higher total LMS than those who did not. In multivariate analysis, prior dental procedures and OMC involvement significantly increased the likelihood of requiring ESS.
