Sixty-five Nigerian and 34 Indian adult human skulls with full eruption of the 3rd molar teeth were examined to ascertain the location of the greater palatine foramen. The location of the foramen from the posterior border of the hard palate was quite consistent, being 0.35 cm in Nigerian and 0.37 cm in Indian skulls. The usually accepted description as opposite the upper 2nd molar was observed for only 13.1% of foramina in Nigerian skulls. The most common position of the foramen was found to be medial or opposite the 3rd maxillary molar, the next most common being between the 2nd and 3rd maxillary molars. The direction of opening of the foramen into the oral cavity was inferiorly in an anteromedial direction in 58.5% Nigerian and 91.1% Indian skulls. In 38.5% Nigerian skulls the opening was in an anterolateral direction. A bilaterally symmetric bony projection extending from the posterior margin of the foramen was observed in 24.6% of the Nigerian and 35.3% of Indian skulls. The palatal vault of was U-shaped in all instances, its height varying from flat to 0.3-0.8 cm.
对65个尼日利亚成年人颅骨和34个印度成年人颅骨进行了检查，这些颅骨的第三磨牙均已完全萌出，以确定腭大孔的位置。腭大孔距硬腭后缘的位置相当一致，在尼日利亚颅骨中为0.35厘米，在印度颅骨中为0.37厘米。在尼日利亚颅骨中，只有13.1%的孔位于上颌第二磨牙相对位置，这是通常所接受的描述。发现该孔最常见的位置是在上颌第三磨牙内侧或相对位置，其次最常见的位置是在上颌第二磨牙和第三磨牙之间。在58.5%的尼日利亚颅骨和91.1%的印度颅骨中，该孔向口腔内开口的方向是向下并朝向前内侧。在38.5%的尼日利亚颅骨中，开口朝向前外侧。在24.6%的尼日利亚颅骨和35.3%的印度颅骨中，观察到从该孔后缘延伸出的双侧对称骨突。所有情况下，腭穹窿均呈U形，其高度从扁平到0.3 - 0.8厘米不等。
