Anatomy of asterion

 Important Aspects of Asterion Anatomy and Radiology

The Asterion Location's Anatomy: The asterion is situated at the intersection of the parietomastoid, occipitomastoid, and lambdoid sutures on the lateral part of the skull

Significance: It acts as a landmark for neurosurgical treatments and indicates the location of the closed mastoid fontanelle.Types: Based on bone structure, they are divided into two types: Type I, which has little or woven bones, and Type II, which does not have woven bones 
Aspects of Radiology
Radiological Landmarks: For radiological measurements and skull evaluations, the asterion serves as a craniometric point 

connected Structures: The junction of the transverse and sigmoid sinuse , in particular, is strongly connected to the dural venous sinuses.

Clinical Implications: Posterolateral surgical techniques and comprehension of the underlying neurovascular structures depend on knowing the position of the asterion. 

Variations and Measurements
Distance Measurements: The asterion to inion, zygomatic arch root, and mastoid tip2 distances are common measurements.

Ethnic and Sexual variances: The position and measures associated with the asterion1 can be affected by anatomical variances based on sex and ethnicity.

Aspects of Radiology
Radiological Landmarks: For radiological measurements and skull evaluations, the asterion serves as a craniometric point

connected Structures: The junction of the transverse and sigmoid sinuses, in particular, is strongly connected to the dural venous sinuses.

Clinical Implications: Posterolateral surgical techniques and comprehension of the underlying neurovascular structures depend on knowing the position of the asterion.

Variations and Measurements
For the sake of diagnosis and surgical planning, DMRIs are utilized to view the asterion and surrounding structures4.
