摘要
通过估算下颌孔与不同解剖标志物的平均距离,确定南印度裔成人和老年人干燥下颌骨中下颌孔的位置,并为下牙槽神经阻滞提供一个具体而精确的部位。 研究共选取 51 个下颌骨,使用游标卡尺测量下颌孔与不同解剖标志物之间的距离。观察并记录是否存在附属下颌孔。下颌孔距前缘的距离为(16.41±2.44)毫米和(16.85±2.55)毫米,距后缘的距离为(10.28±2.08)毫米和(10.13±2.02)毫米。02 mm,距下颌切迹分别为 22.5±3.13 mm 和 21.9±3.08 mm,距下颌基底分别为 23.72±3.37 mm 和 24.5±3.27 mm,距第三磨牙分别为 15.27±11.99 mm 和 16.85±11.60 mm,距后磨牙三棱锥顶分别为 18.28±3.02 mm 和 19.79±3.18 mm。左右两侧的测量值无明显差异。测量值与盂角呈负相关。下颌孔的精确定位对下颌牙科手术前有效阻断下牙槽神经非常重要。本研究确定了下颌孔位置相对于各种解剖标志物的双侧对称性,以及盂角在下颌孔定位中的作用。
Location of mandibular foramen in dry mandibles in relation to various anatomical landmarks
To localize the mandibular foramen in dry mandibles of adult and old age groups of South Indian origin by estimating its average distance from different anatomical landmarks and to provide a specific and precise site for inferior alveolar nerve block. : A total of 51 mandibles were taken for the study and the distance between the mandibular foramen and the various anatomical landmarks were measured using a digital vernier caliper. Presence of accessory mandibular foramen was observed and recorded. Difference between the sides and the correlation between the gonial angle and various distances were carried out.:Distance of mandibular foramen from anterior border was 16.41±2.44 mm and 16.85±2.55 mm, from posterior border was 10.28±2.08 mm and 10.13±2.02 mm, from mandibular incisure 22.5±3.13mm and 21.9±3.08mm, from mandibular base 23.72±3.37 mm and 24.5±3.27 mm, from third molar 15.27±11.99 mm and 16.85±11.60 mm, from apex of retro molar trigone 18.28±3.02 mm and 19.79±3.18 mm on right and left side respectively. There was no significant difference between the measurements of right and left sides. The measurements had a negative association with gonial angle. Accessory foramina were found to be present in 21and 23 mandibles on right and left side respectively.:Precise localization of mandibular foramen is clinically very important to achieve effective inferior alveolar nerve block prior to dental surgeries in the lower jaw. The present study establishes the presence of bilateral symmetry in the position of mandibular foramen with respect to various anatomical landmarks and the utility of gonial angle in localizing the mandibular foramen.
