Evaluation of the maxillary sinus anatomy prior to sinus lift procedures is important to avoid surgical complications due to the close anatomical relationship between the posterior maxillary region and the maxillary sinüs.
In order to avoid traumatizing the posterior superior alveolar artery and to prevent perioperative bleeding, locating the exact position of the artery is imperative before the surgical procedures.
150 CBCT scans were evaluated. The distance from the inferior border of the PSAA to the alveolar crest (the vertical line from the artery to the crest) and floor of the maxillary sinus, the distance from PSAA to medial sinus wall, nasal septum, zygomatic arch, position, the distance from the floor of maxillary sinüs to the alveolar crest and diameter of the PSAA were assessed. Locations of the artery were classified.
The artery diameters were mostly ≥ 1 mm. The artery was mostly intraosseous (59.7%), 21.7% was superficial and only 18.7% was intra-sinuscular.
The location of PSAA is intraosseous in most patients. The artery diameters were mostly ≥ 1 mm and we can say that increasing the size also increases the risk of complications.
在进行窦提升手术前，评估上颌窦解剖结构非常重要，因为上颌后区与上颌窦之间的解剖关系非常密切。
为了避免损伤上颌后上牙槽动脉，并防止围手术期出血，在手术前必须准确定位动脉的位置。
评估了 150 例 CBCT 扫描。测量了 PSAA 下缘到牙槽嵴（动脉到牙槽嵴的垂直线）和上颌窦底的距离、PSAA 到内侧窦壁、鼻中隔、颧骨弓、位置、上颌窦底到牙槽嵴的距离以及 PSAA 直径。评估了动脉的位置。
动脉直径大多≥1 毫米。动脉大多位于骨内（59.7%），21.7%位于骨表面，只有 18.7%位于窦内。
大多数患者 PSAA 的位置为骨内。动脉直径大多≥1 毫米，我们可以说，动脉尺寸越大，并发症的风险也越高。
