乌鲁木齐市维吾尔族正常人群鼻腭管解剖形态的锥形束CT研究

The Study on Nasal Tube's Anatomical Morphology for Uygur Normal Population in Urumqi by Using Cone Beam Computed Tomography

目的:利用锥形束CT(CBCT)分析乌鲁木齐市维吾尔族正常人群鼻腭管的解剖形态。方法:选择2016年9月-2017年9月于新疆维吾尔自治区人民医院口腔科行CBCT检查的维吾尔族正常人影像学资料,共160例,其中男82例,女78例。对其鼻腭管直径、长度,唇侧骨长度、厚度及鼻腭管水平面直径进行测量分析。结果:鼻腭管的长度、直径及其唇侧骨板的长度、直径与性别及年龄均有一定的相关性,除鼻腭管高位直径外,男性鼻腭管测量项目均大于女性,且差异有统计学意义(P<0.05)。随着年龄的增加,鼻腭管直径、长度及鼻腭管口腔侧开口直径均逐渐增大,鼻腭管唇侧骨厚度及其唇侧骨长度逐渐减小,且差异有统计学意义(P<0.05)。鼻腭管冠状面各解剖形态间鼻腭管及其唇侧骨各测量项目差异无统计学意义(P>0.05)。结论:维吾尔族正常人群鼻腭管的解剖结构差异与其性别及年龄相关,术前准确地分析有利于避免损伤鼻腭管,提高上前牙区种植修复的成功率。

Objective To analyze the structure of tnasal tube’s anatomical morphology for Uygur normal population in Urumqi by using cone beam computed tomography.Methods A total of160Uyghur imaging data were collected from the Department of Stomatology,People's Hospital of Xinjiang Uygur Autonomous Region from September2016to September2017,including82males and78females.The diameter and length of the nasal canal,the length of the labial bone,the thickness and the diameter of the nasal tube were measured and analyzed.Results The length and diameter of the sinus tube and the length and diameter of the labial plate were related to gender and age.Except for the high diameter of the sinus tube,the male sinus tube measurement items were larger than women,and the difference was statistically significant(P<0.05).With the increase of age,the diameter and length of the sinus tube and the diameter of the oral side opening of the sinus tube gradually increased.The thickness of the labial bone and the length of the labial bone of the sinus tube gradually decreased,and the difference was statistically significant(P<0.05).There was no significant difference in the measurement items between the sinus and the labial bone of the sinus of the sinus tube(P>0.05).Conclusion The anatomical structure of the sinus tube in the normal Uygur population is related to gender and age.Accurate analysis before surgery is beneficial to avoid damage to the nasal tube and improve the success rate of implant restoration in the upper anterior region.
