【摘要】：目的:了解下颌管的解剖位置和变异尤为重要,CBCT能为下颌种植手术和下颌磨牙拔除术以及下颌骨矢状劈开术提供理论参考和临床指导。利用CBCT初步探讨维吾尔族成年人下颌神经管分支的发生率及分型。方法:收集2014-2016年在新疆医科大学第一附属医院口腔科就诊病人214例,征得患者同意登记个人信息并拍摄CBCT。利用CBCT评估这214名维吾尔族患者的下颌管及其有无分支。左右两侧研究了(n=428).在矢状位、冠状位、横断位及三维全景位对图像进行必要重建和评估。观察患者有无下颌管分支,描述分支变异情况及其走向并进行统计学分析。结果:214例(428侧)维吾尔族患者,51例(23.8%)观察到下颌管分支,其中女31例(14.48%),男20例(9.34%),发现下颌管双分支1例,最为常见的下颌管分支为前行管(第Ⅲ类),发生率为8.88%,其次是磨牙管(第Ⅰ类),发生率为8.41%和牙管(第Ⅱ类),发生率为4.67%,最后是颊舌管(第Ⅳ类),发生率为1.87%。结论:利用CBCT不但能够清晰观察下颌神经管的三维影像,而且能够精确地显示下颌神经管的位置和走行,这将大大降低并发症的发生。通过CBCT能够很好地观察下颌管有无分支这一解剖结构。本文通过回顾性分析214例维吾尔族成年人下颌神经管CBCT,发现维吾尔族成年人下颌神经管分支发生率与其它种族比较较低,但与国内研究报导基本一致。对选择合适的治疗方案有临床实用价值。
[Abstract]:Objective: to understand the anatomical position and variation of mandibular canal. CBCT can provide theoretical reference and clinical guidance for mandibular implantation, mandibular molar extraction and sagittal split mandibular surgery. The incidence and classification of mandibular canal branches in Uygur adults were studied by CBCT. Methods: from 2014 to 2016, 214 patients were enrolled in the Department of Stomatology, the first affiliated Hospital of Xinjiang Medical University. They registered their personal information with the consent of the patients and photographed CBCT.. The mandibular canal and its branches were evaluated by CBCT in these 214 Uygur patients. The left and right sides were studied (n 鈮，
