The aim of this study was to assess the anatomical features of the alveolar antral artery (AAA) in edentulous patients using cone beam computed tomography (CBCT).
The sample consisted of 191 CBCT scans of maxillary sinuses (n=382) of male (n=59) and female (n=132) edentulous patients (age: 38-89 years).
The images were analyzed in Dolphin™ 11.9 software. Visualization, location, and diameter of the AAA was registered.
AAA was present in 88.5% of the assessed maxillary sinuses. Bilateral visualization was predominant 77% (P<0.0001). The mean vertical distance from the most anterior part of the AAA to the sinus floor was 7.9±6mm in female patients (both sides) and 12±7.22mm on the right side and 10.9±6.86mm on the left side in males. The mean diameter of the AAA was 1.2±0.7mm on both sides in females. In males, the diameter was significantly (P<0.05) larger: 1.5±0.62mm on the right side and 1.4±0.69 on the left side in females.
The AAA had a higher visualization rate, better visualization, and larger diameter when it was present bilaterally in male and female patients.
本研究旨在通过锥形束 CT（CBCT）评估无牙患者牙槽嵴顶动脉（AAA）的解剖特征。
样本包括 191 例上颌窦 CBCT 扫描（n=382），其中男性（n=59）和女性（n=132）无牙患者（年龄：38-89 岁）。
在 Dolphin™ 11.9 软件中分析图像。记录 AAA 的可视化、位置和直径。
88.5%评估的上颌窦中存在 AAA。双侧可视化为主，占 77%（P<0.0001）。女性患者（双侧）AAA 最前缘至窦底的垂直距离平均值为 7.9±6mm，男性右侧为 12±7.22mm，左侧为 10.9±6.86mm。女性双侧 AAA 的平均直径为 1.2±0.7mm。男性右侧直径为 1.5±0.62mm，左侧直径为 1.4±0.69mm，显著大于女性（P<0.05）。
男性和女性患者双侧 AAA 具有更高的可视化率、更好的可视化效果和更大的直径。
