Abstract

Asterion is the junction of lambdoid, parietomastoid and occipitomastoid sutures and it corresponds to the location of the posterolateral fontanelle. It is close related to the location of junction of transverse and sigmoid sinuses. Mastoid process, posterior end of zygomatic arch, external occipital protuberance and lambda are bony features in close proximity of asterion. In the present study we measured the distance between asterion and each of aforementioned bony points. Twenty human dry skulls were included in this study. Distance between asterion and mastoid process was 43.65 ± 6.75 mm on the left side and 45.01± 6.04mm on the right side. Distance between asterion and posterior end of zygomatic arch was 43.97 ± 7.37 mm on the left side and 43.95± 7.02 mm on the right side. Distance between asterion and external occipital protuberance was 62.59 ± 8.83 mm on the left side and 54.75 ±5.57mm on the right side. Distance between asterion and lambda was 81.40 ± 7.36 mm on the left side and 82 ± 4.96 mm on the right side. In 84 % of the cases asterion was at the junction of transverse and sigmoid sinuses. In 12% of the cases asterion was below the junction of transverse and sigmoid sinuses. In 4 % of the cases asterion was above the junction of transverse and sigmoid sinuses. Asterion is the essential point to indicate safety zone for surgical approach and to determine sex and age. It is of great interest of anatomists, anthropologists, forensic experts, radiologists and neurosurgeons. © 2019, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
