This study aimed to assess and analyze the morphology and dimensions of the nasopalatine canal (NPC), as well as the adjacent buccal osseous plate (BOP), and to investigate the effect of gender, edentulism, NPC types, absence of maxillary central incisors (ACI) and age on the NPC and BOP, using cone beam computed tomography (CBCT). A total of 124 CBCT examinations (67 female and 57 male patients) were retrospectively included and evaluated. The assessment of the dimensions of the NPC, as well as the dimensions of the adjacent BOP, was performed by three Oral and Maxillofacial Radiologists on reconstructed sagittal and coronal CBCT sections under standardized conditions. Regarding the dimensions of the NPC and the adjacent BOP, the mean values were significantly higher among males than females. Furthermore, edentulous patients showed a significant reduction in BOP dimensions. Additionally, NPC types showed a significant effect on the length of the NPC, and the ACI had a significant effect on reducing BOP dimensions. Age had a significant effect on the diameter of the incisive foramen, with the mean values generally increasing with an increasing age. CBCT imaging of this anatomical structure contributes significantly to its full assessment.
本研究旨在利用锥形束计算机断层扫描（CBCT）评估和分析鼻腭管（NPC）以及相邻颊侧骨板（BOP）的形态和尺寸，并研究性别、无牙症、NPC类型、上颌中切牙缺失（ACI）和年龄对NPC和BOP的影响。共回顾性纳入并评估了124例CBCT检查（67例女性和57例男性患者）。由三名口腔颌面放射科医生在标准化条件下对重建的CBCT矢状面和冠状面图像进行NPC尺寸以及相邻BOP尺寸的评估。关于NPC和相邻BOP的尺寸，男性的平均值显著高于女性。此外，无牙患者的BOP尺寸显著减小。另外，NPC类型对NPC的长度有显著影响，ACI对减小BOP尺寸有显著影响。年龄对切牙孔直径有显著影响，平均值通常随年龄增长而增加。该解剖结构的CBCT成像对其全面评估有显著贡献。
