Maksiller sinüsün anatomik değişiklikleri ve patolojilerinin panoramik radyografi ve konik ışınlı bilgisayarlı tomografi ile değerlendirilmesi
Özet
Evalution of maxillary sinüs anatomic changes and Pathologies, using Panoramic Radiography and ConeBeam Computed Tomography. The purpose of this study is to investigate the different reason of many patients who having CBCT and Panoramic radiograph; to examine lesions appeared on maxillary sinus and the accuracy of anatomic changes during Panoramic Radiography (which is a method used in dental implant planning and requested frequently in radiographical diagnosis procedure) by CBCT; to determine the benefits and limits of panaromic radiograph's during the analysis of maxillary sinuses. In this study, patients applied between 2011-2012 ,with different reasons (who have CBCD and Panoramic scan images obtained) are evaluated. Changes and pathologies of 566 Maxillary Sinus areas of 283 patients between ages 18-83 are analyzed; but also changes in sinonasal area of the side of the sinus of patients are examined. In this research, Iluma brand dental volumetric tomography device with Coronal, Axial, Sagittal, Cross-Sectional slices (2mm) and Planmeca Proline XC Panoramic device are used. Panoramic Radiography presentation of patients with CBCD image is evaluated by three researchers. Results are statistically significant at p<0.05. When seen in CBCT, Sensitivity of diagnosis with panoramic radiography of Nasal Septum Deviations is 28.8%, Haller is 12.9%, Pneumatisation 70.8%, Antral Septa is 38.4%, Hypoplasia is 92.9%, Exositosis 14.7%, Mucosal Thickening is 31.9%, Polipoid Lesion is 20.2%, discontinuity of the sinus floor is 0.0%, Opacification is 34.5%, tooth root being in sinus is 92.5%, tooth root being outside the sinus is 73.9%, tooth root being adjacent to sinus is 29.3%, apical lesion is 42.7%, periodontitis is 64.5%, Root Canal is 82.1%, Edentulousness is 100%. Panoramic radiography is not enough for evaluated of the patologie and variation of the maxillary sinus. İn this reson CBCT is the most available imaging method for diagnosis and examination of the sinüs paranasales.
