Abstract :Objectives: The relationship between the mastoid triangle and the localization of the Asterion can be used in craniotomy and posterolateral surgical approaches. Therefore, we aimed to identify the relationship between the localization of the Asterion and mastoid triangle in dry skulls and its effect on surgery. Methods: Our study was performed on 93 adult skulls obtained from bone collections of the Anatomy Departments of Necmettin Erbakan University and Akdeniz University. The mastoid triangle, Asterion and linear distances between them were measured for to determine the localization of the Asterion. Results: The Asterion was located just above the Frankfurt horizontal plane on the left sides of the skulls in 54 insert ignore into journalissuearticles values(58.1%); specimens and on the right sides of the skulls in 71 insert ignore into journalissuearticles values(76.3%);. It was located below the Frankfurt horizontal plane on the left sides of the skulls in 39 insert ignore into journalissuearticles values(41.9%); specimens; and on the right sides of the skulls in 19 insert ignore into journalissuearticles values(20.4%);. There was a positive correlation between the distance of Asterion to apex of the mastoid process insert ignore into journalissuearticles values(r=0.832);. Conclusion: The relationship between the mastoid process and the Asterion can be used for determination of the dural venous sinuses and neighboring neurovascular structures, in retrosigmoid posterolateral surgical approaches.
