Two hundred CBCT records were included in the study. The patients were divided into dentate, partially dentate and edentulous. Methods The diameter and type of the PSAA (intrasinus-intraosseous-superficial), the distance between the lower border of the PSAA and alveolar crest; the bone height measured from the floor of the sinus to the crest of the ridge; the distance from the lateral wall of the PSAA to the medial wall of the maxillary sinus, presence of septa and pathology were evaluated.
Results On the right side, PSAA was detected in 86.5% and in the left, 84.5%. Intraosseous type of PSAA was most common type on right (50%) and left (51.5%). The average distances between the PSAA and the alveolar crest were 17.80±3.59 mm on the right and 17.83±3.61 mm on the left side. There was no significant correlation between age and the diameter of the PSAA (p>0.05). Conclusions The observation of PSAA on CBCT slices is high. Preoperatively CBCT imaging can prevent potential vascular damages around maxillary sinus.}, number={1}, publisher={Selçuk Üniversitesi}, organization={Yok}
