Abstract

Context: The jugular foramen is one of the most fascinating foramen present at the base of the skull attracting the imagination of many Anatomists worldwide as many important structures pass through it, and amongst them the intriguing structure is the internal jugular vein. The shape and size of the jugular foramen is related to the size of the internal jugular vein and the presence or absence of a prominent superior bulb. As most of the textbooks of Anatomy describe that the right jugular foramen is usually larger than the left jugular foramen. Henceforth the present study was undertaken in 55 skulls from the dept. of Anatomy. Measurements were taken with the help of sliding vernier caliper. Study type: C ross-sectional descriptive type. Place and period of study: Department of Anatomy, Rajshahi Medical College, Rajshahi and Pabna Medical College, Pabna from April 2010 to June 2011. Materials and Methods: Total fifty five (55) human adult skulls were collected from the Anatomy department of Rajshahi Medical College, Rajshahi and Pabna Medical College, Pabna at different times of the study period. The study was conducted to observe variations in the structure of the jugular foramen of the human’s skull. Result: Out of 55 skulls (110 foramina) studied, the presence of dome indicating the presence of jugular bulb was found bilaterally in 100% of cases. 58.18% of cases showed that the size of right foramina were larger than the left foramina whereas 20% of cases showed that right foramina were equal to the left and in 21.82% of cases the left foramina were larger than the right side foramina. An important observation in the present study was the presence of either complete or partial septation in the jugular foramen. Conclusion: The findings of the study reveals that there are some differences among some parameters. The variations are might be due to the geographical variations of the skeletons. It needs further study with larger sample size from different geographical areas of Bangladesh.

人颅骨颈静脉孔结构的变异

背景:颈静脉孔是颅骨底部最迷人的孔之一，吸引了世界上许多解剖学家的想象力，因为许多重要的结构都经过它，其中最有趣的结构是颈内静脉。颈静脉孔的形状和大小与颈内静脉的大小和是否有突出的上球有关。正如大多数解剖学教科书所描述的那样，右颈静脉孔通常比左颈静脉孔大。此后，目前的研究是在解剖系的55个头骨上进行的。测量是借助滑动游标卡尺进行的。研究类型:C横截面描述型。学习地点和时间:2010年4月至2011年6月，拉杰沙希医学院解剖系，拉杰沙希和帕布纳医学院。材料与方法:在研究期间的不同时间，从拉杰沙希医学院和帕布纳医学院解剖学系收集了55(55)个成人颅骨。这项研究是为了观察人类颅骨颈静脉孔结构的变化。结果:在研究的55个颅骨(110个孔)中，100%的病例发现双侧颈静脉球存在穹窿。58.18%的病例显示右侧孔大于左侧孔，20%的病例显示右侧孔与左侧孔相等，21.82%的病例显示左侧孔大于右侧孔。本研究的一个重要观察结果是颈静脉孔存在完全或部分分隔。结论:研究结果显示，部分参数之间存在一定差异。这些差异可能是由于骨骼的地理差异造成的。这需要进一步的研究，从孟加拉国不同的地理区域更大的样本量。DOI: http://dx.doi.org/10.3329/bja.v10i2.17281孟加拉解剖学杂志，2012年7月，Vol. 10 No. 2 pp 45-49
