PURPOSE
The objectives were to study the morphometry of occipital condyles and to find the incidence of third occipital condyle in Indian skulls.
MATERIALS AND METHODS
In the present study, 140 occipital condyles from 70 dry skulls were analysed. The length, width, height of occipital condyles, the anterior and posterior intercondylar distances was measured.
RESULTS
The average length, width and height of occipital condyle were 21.9 mm, 11.26 mm and 10.2 mm respectively. The average anterior and posterior intercondylar distances were 18.7 mm and 38.7 mm respectively. Among our specimens, 2 skulls (2.86%) had a third occipital condyle.
CONCLUSION
We believe that the data of the present study may provide anatomical reference to neurosurgeons and thus help in surgical procedures around the craniovertebral junction. The clinical and phylogenetic significance of the third occipital condyle has been discussed.
目的
本研究旨在探讨枕髁的形态学特征，并确定印度颅骨中第三枕髁的发生率。
材料与方法
本研究分析了70个干燥颅骨的140个枕髁。测量枕髁的长度、宽度、高度以及髁间前后距离。
结果
枕髁的平均长度、宽度和高度分别为21.9毫米、11.26毫米和10.2毫米。髁间前后平均距离分别为18.7毫米和38.7毫米。在我们的标本中，2个颅骨（2.86%）有第三枕髁。
结论
我们认为本研究的数据可为神经外科医生提供解剖学参考，从而有助于颅颈交界区周围的手术操作。文中还讨论了第三枕髁的临床及系统发育意义。
