Cone Beam CT Evaluation of Maxillary Sinus and Posterior Superior Alveolar Artery

Background The aim of this study was to investigate the diameter, location, and frequency appearance posterior superior alveolar artery (PSAA), presence septa pathology in maxillary sinus on cone-beam computed tomography (CBCT) slices. Two hundred CBCT records were included study. patients divided into dentate, partially dentate edentulous. Methods diameter type PSAA (intrasinus-intraosseous-superficial), distance between lower border crest; bone height measured from floor crest ridge; lateral wall medial sinus, evaluated. Results On right side, detected 86.5% left, 84.5%. Intraosseous most common (50%) left (51.5%). average distances 17.80±3.59 mm 17.83±3.61 side. There no significant correlation age (p>0.05). Conclusions observation slices is high. Preoperatively imaging can prevent potential vascular damages around sinus.
