Endoscopic Surgical Treatment of Chronic Maxillary Sinusitis of Dental Origin
Purpose
Chronic maxillary sinusitis of dental origin (CMSDO) is a common disease that requires treatment of the sinusitis as well as of the odontogenic source. We present our surgical experience performing contemporary treatment of the odontogenic source and endoscopic sinus surgery (ESS) in patients with CMSDO.
Patients and Methods
Seventeen patients with CMSDO underwent contemporary treatment of the odontogenic source and ESS. Five patients presented chronic oroantral fistula (OAF); 5 patients presented odontogenic cysts occupying the maxillary sinus; 2 patients had inflammatory cysts of the molars; 2 patients had maxillary sinus infection secondary to peri-implantitis; 3 patients had foreign bodies pushed through the root canal into the sinus. The first surgical step was the treatment of the odontogenic source. The second step was ESS with opening and calibration of the maxillary natural ostium.
Results
Foreign bodies were extracted from the sinuses through the endonasal approach. No major complications after ESS were observed. The average time for ESS was ±25 minutes. Good distant results without symptoms and complete closure of the fistula were obtained in all patients.
Conclusion
When significant sinus disease is found, an endoscopic approach to drainage in all of the involved sinuses can promote predictably successful closure of OAF. The endoscopic approach to chronic maxillary sinusitis of dental origin is a reliable method associated with less morbidity and lower incidence of complications.
