Study of Craniometric Point as a Landmark in Performing Posterolateral Surgeries on Skull
Keywords:
Anatomy, Asterion, Sigmoid Sinus, Surgical ApproachAbstract
Introduction: The asterion is craniometric point on the lateral side of skull. Importance of asterion lies in that it is primary landmark in performing posterolateral surgeries on skull.
Material and Methods: In 100 adult dry skulls measurements were taken on right and left sides of the skull using digital Vernier callipers. Two parameters were noted: Distance of the asterion to the root of zygoma and to the tip of the mastoid process.
Result: The mean distance of the asterion to the root of zygoma on right side was 56.15+2.40 mm and on left side was 57.48+2.68 mm. The mean distance of the asterion to the tip of the mastoid process on the right side was 48.77+2.23 mm and on the left side was 47.45+2.62 mm.
Conclusion: The accurate location of asterion using the root of the zygoma and the tip of the mastoid process needs to be further evaluated using more sophisticated studies.
