Abstract

The purpose of this study was to evaluate in dry skulls the length and angle between the greater palatine foramen and the foramen rotundum in both the frontal and sagittal planes. In 50 human skulls from the department of morphology, the distance and angulation required to reach the foramen rotundum through the greater palatine canal were measured in the frontal and sagittal planes. A stylet was introduced up to the foramen rotundum in each greater palatine canal and fixed. The skulls were then photographed from a front and lateral view (both right and left). Finally, the stylets were photographed on graph paper. These images were analyzed with Photoshop software. In the frontal plane, mean angulations of 5.32 degrees on the right side and 6.15 degrees on the left side were obtained. In the sagittal plane, mean angulations of 61.66 degrees on the right side and 61.81 degrees on the left side were obtained. Finally, the mean length required to reach the foramen rotundum was 31.95  mm on the right side and 32.49  mm on the left side. Some of these results differ from those stated in the foreign literature (10 degrees front, 70 degrees sagittal). These differences should be considered for both clinical practice and teaching in Chile.
