The lack of the available bone in the posterior maxilla is determined by the range of anatomical and topographical factors. Lateral sinus floor elevation is the procedure for vertical augmentation in this region. Several complications may occur while performing a lateral sinus lift and bleeding due to alveolar antral artery (AAA) damage is one of them.
The of the study is to analysis the different literature on AAA topographical features on cadaver species and on radiographic methods.
A search of the English language literature was performed by three independent readers in the PubMed electronic database. Articles published between 2013 and 2018 on cadaver and radiographic studies were included.
The analysis included 9 articles. AAA prevalence in cadavers was 100% but AAA bone signs in CBCT studies varied between 32% and 93%. The diameter varied from 0.91 mm to 3.6 mm, and the distances from AAA to the sinus floor and to the alveolar ridge crest were 7.38-9.97 and 14.6-18.66 mm respectively.
Our literature analysis showed the difference between AAA prevalence in cadavers and in CBCT scans. The results show that even proper pre-operative planning of the lateral sinus lift with CBCT cannot guarantee avoiding AAA damage while performing the surgery.
上颌后牙区可用骨量不足由多种解剖和地形因素决定。外侧上颌窦底提升术是该区域垂直骨增量的手术方法。在进行外侧上颌窦提升术时可能会出现多种并发症，其中因损伤牙槽窦动脉（AAA）导致的出血就是其中之一。
本研究的目的是分析关于尸体标本上AAA地形特征以及影像学方法的不同文献。
由三位独立读者在PubMed电子数据库中检索英文文献。纳入2013年至2018年发表的关于尸体标本和影像学研究的文章。
分析纳入9篇文章。尸体标本中AAA的发生率为100%，但CBCT研究中AAA的骨征在32%至93%之间变化。其直径在0.91毫米至3.6毫米之间，AAA到上颌窦底和牙槽嵴顶的距离分别为7.38 - 9.97毫米和14.6 - 18.66毫米。
我们的文献分析显示了尸体标本和CBCT扫描中AAA发生率的差异。结果表明，即使使用CBCT对外侧上颌窦提升术进行适当的术前规划，在手术过程中也不能保证避免AAA损伤。
