摘要： 目的 用锥形束CT（CBCT）分析上颌前牙区鼻腭管及唇侧骨的形态。方法 收集并筛选出712例正常人上颌前牙区CBCT影像,对其鼻腭管、唇侧骨的相关参数进行测量分析。结果 研究对象年龄范围在5~80岁,男306例（43.0%）,女406例（57.0%）。鼻腭管矢状面平均长度为（13.58±2.22）mm,矢状面平均直径为（3.37±1.58）mm,唇侧骨矢状面平均厚度为（7.63±1.50）mm,鼻腭管直径与唇侧骨厚度相对值为0.46±0.19,长度相对值为0.69±0.10。结论 各年龄段人群之间鼻腭管的直径、长度和唇侧骨厚度存在一定差异。儿童的鼻腭管直径小于成人（P<0.000 1）,唇侧骨厚度大于成人（P<0.000 1）。随着年龄的增长,鼻腭管直径和长度均呈递增趋势,唇侧骨厚度递减。男性的鼻腭管直径、长度和唇侧骨厚度、长度均大于女性。

Abstract: Objective To provide an anatomical guidance for surgical operations, we evaluated the general anatomical morphology of nasopalatine canal(NPC) and maxillary anterior region.Methods Seven hundred and twelve cone-beam computed tomography(CBCT) images of normal people were collected. Three experienced oral radiologists used INFINITT software to evaluate the relevant parameters of the NPC and labial bone. Results Seven hundred and twelve subjects ranged in age from 5 to 80, including 306 males(43.0%) and 406 females(57.0%). The mean length of the NPC was (13.58±2.22) mm, the mean diameter was (3.37±1.58) mm and the mean thickness of labial bone was (7.63±1.50) mm. The ratio of the thickness between NPC and labial bone is 0.46±0.19, and the ratio of their length is 0.69±0.10.Conclusion The study revealed statistically significant differences in the diameter of the NPC, length of the NPC and thickness of the labial bone. The mean diameter of the NPC was shorter(P<0.000 1) and the labial bone was thicker(P<0.000 1) in children. We also found that the mean length and diameter of the NPC had a trend to become longer with age, while the labial bone became thinner. Additionally, our study showed that gender exerted a significant influence upon the NPC and the labial bone, with larger values in males than in females.
