Alveolar antral artery (AAA) damage can cause perioperative hemorrhage during osteotomy. The aim of this study was to assess the prevalence of AAA presence and evaluate its characteristics using cone-beam computerized tomography (CBCT). One hundred maxillary sinuses were evaluated from 70 CBCT scans. The anteroposterior dimension of each sinus was divided into four equal quarters, and the main artery presence was noted for each section. Arterial diameter as well as distance to sinus floor and to alveolar ridge were measured, and the position of the main artery according to its location relative to the lateral sinus wall was determined. In cases where additional arteries were detected, their diameter and position were also determined. Artery prevalence was 87.0%. In 42% and 8% of the cases respectively, a second and third artery were visualized. No significant association was found between the prevalence of the arteries and age of participants. However, the prevalence of a secondary artery among men (56.4%) was significantly higher than in women (32.8%) (P = .02). Moreover, the main artery diameter was significantly different between sections (P = .014), as was its position. AAA was radiographically detectable in the majority of studied sinuses. In 2 cases, 3 arteries were visible. Arteries with a diameter ≥ 2 mm were not frequent. However, arteries exceeding this diameter must be factored in when choosing surgical techniques. The findings of this study suggest there might be accessory arteries associated with AAA. Therefore, preoperative radiological CBCT examination is necessary prior to any sinus floor elevation surgery.
牙槽窦动脉（AAA）损伤可导致截骨术中围手术期出血。本研究的目的是评估AAA的存在率，并使用锥形束计算机断层扫描（CBCT）评估其特征。从70例CBCT扫描中评估了100个上颌窦。每个窦的前后径被分成四个相等的部分，并记录每个部分主要动脉的存在情况。测量动脉直径以及到窦底和牙槽嵴的距离，并根据其相对于外侧窦壁的位置确定主要动脉的位置。在检测到额外动脉的情况下，也确定其直径和位置。动脉存在率为87.0%。分别在42%和8%的病例中观察到第二和第三支动脉。未发现动脉存在率与参与者年龄之间存在显著关联。然而，男性中二级动脉的存在率（56.4%）显著高于女性（32.8%）（P = .02）。此外，各部分之间主要动脉直径（P = .014）及其位置也存在显著差异。在大多数研究的窦中，AAA在影像学上是可检测到的。在2例中可见3支动脉。直径≥2 mm的动脉并不常见。然而，在选择手术技术时必须考虑超过该直径的动脉。本研究结果表明可能存在与AAA相关的副动脉。因此，在进行任何窦底提升手术之前，术前进行CBCT影像学检查是必要的。
