Teeth in the maxillary sinus--imaging and management
1Department of Oral and Maxillofacial Surgery, Soroka Medical Centre, Ben-Gurion University of the Negev, Beer-Sheva, Israel.
Purpose:
To evaluate the images obtained by CT in diagnosis and treatment plan of teeth in the maxillary sinus.
Methods:
Twelve patients with teeth in the maxillary sinus were studied by plain film radiography (PFR) and by CT with a dental software programme, which displays multiple panoramic and cross-sectional views of the mandible and maxilla. The three-dimensional morphology of the tooth, its inclination, proximity to the sinus wall, surgical planning and prediction of prognosis and complications were estimated on both PFR and on CT scans and scored.
Results:
The radiographical features interpreted from PFR were fair or poorly diagnosed whereas CT provided excellent features. The surgical approach of choice was based on CT interpretation.
Conclusion:
CT is useful for diagnosis and treatment planning of teeth in the maxillary antrum.
