【摘要】：目的统计分析四川地区成年人群中分叉下颌管发生概率,并总结下颌管各分叉类型及发生率与走行方式和各自形态特征。方法根据纳入和排除标准收集500例患者(共计1 000侧下颌骨)的锥形束CT(CBCT)影像资料,对所收集的资料进行观察分析,并记录数据,对下颌神经管分支的类型及其特征进行归纳和分类。结果 500例患者中分叉下颌管的发生率为13.8%(69/500),共发生于92侧(9.2%)的下颌骨中。其中最常见的类型为磨牙后管,其次为向牙根及颊舌向分支,最少见的类型为向前走行的分支。分支的平均直径和长度分别为0.90、9.39 mm。结论本研究使用CBCT作为研究手段,得出的分叉下颌管在四川地区成年人群中的发生率要明显高于以前报道的使用全景片作为研究手段的研究;并且CBCT对下颌管及其分支的三维走行及形态特征的表现能力优于全景片。
[Abstract]:Objective to analyze the probability of occurrence of bifurcation mandibular canal in adult population in Sichuan province, and to summarize the types, incidence, walking pattern and morphological characteristics of mandibular canals.Methods according to the inclusion and exclusion criteria, the CT CBCTs of the conical tracts of 500 patients (1 000 mandibles) were collected, the collected data were observed and analyzed, and the data were recorded.The types and characteristics of mandibular nerve canal branches were summarized and classified.Results the incidence of bifurcation mandibular canal in 500 patients was 13.8% 69 / 500, which occurred in 92 sides of the mandible.The most common type is the posterior molar tube, the second is the root and buccal branch, and the rarest type is the forward branch.The mean diameter and length of the branches were 0.90 ~ 9.39 mm.Conclusion the incidence of bifurcation mandibular canal in adult population in Sichuan area was significantly higher than that of panoramic film in Sichuan area.Moreover, CBCT was superior to panoramic film in displaying the three-dimensional walking and morphological features of mandibular canal and its branches.
