Jugular foramen of human skull is one of the most interesting foramina. It is a complex bony canal, numerous vital structures, including nerves and vessels are transmitted through it. Most of the intracranial and extra cranial lesions of posterior cranial fossa might affect the structures in jugular foramen in addition to intrinsic abnormalities. As the neurosurgeons have become courageous in approaching this area, so there is a need to become familiar with this area. Hence, the present study was done to examine the anatomy of jugular foramen, including its morphological features and dimensions.
The study was carried out on 50 dried skulls. 100 jugular foramina were studied on both right and left side of skulls. The length, width of jugular foramen and width and depth of jugular fossa were measured using vernier calipers. Presence of dome, complete and incomplete septation was also looked for.
The mean right and left anteroposterior diameter, latero-medial diameter, area, jugular fossa width, depth in our study was 11.22, 16.52, 187.34, 6.83, 11.58 mm and 9.52, 16.02, 153.2, 5.69, 11.13 mm. Dome was present in jugular foramen in 74% on the right side and 58% on the left side. Complete septation in jugular foramen is seen in 44% on the right side and 42% on the left side.
This study will help the neurosurgeons while doing surgery in this region.
人类颅骨的颈静脉孔是最引人关注的孔道之一。它是一个复杂的骨性管道，有众多重要结构，包括神经和血管通过其中。除了其自身的异常情况外，后颅窝的大多数颅内和颅外病变可能会影响颈静脉孔内的结构。随着神经外科医生在处理该区域时变得更加大胆，因此有必要熟悉这个区域。因此，本研究旨在检查颈静脉孔的解剖结构，包括其形态特征和尺寸。
本研究对50个干燥颅骨进行。对颅骨左右两侧的100个颈静脉孔进行了研究。使用游标卡尺测量颈静脉孔的长度、宽度以及颈静脉窝的宽度和深度。还观察了穹窿、完全和不完全分隔的情况。
在我们的研究中，右侧和左侧的平均前后径、内外径、面积、颈静脉窝宽度、深度分别为11.22、16.52、187.34、6.83、11.58毫米和9.52、16.02、153.2、5.69、11.13毫米。右侧颈静脉孔中有74%存在穹窿，左侧为58%。右侧颈静脉孔中44%可见完全分隔，左侧为42%。
这项研究将有助于神经外科医生在该区域进行手术。
