Study Notes
Skull Positioning Lines
-
Glabellemeatal Line (GML): Connects the glabella (forehead area) to the external auditory meatus (EAM), also known as the porion.
-
Orbitomeatal Line (OML): Positioned between the outer canthus of the eye and the EAM; also referred to as the radiographic base line and is frequently utilized in imaging.
-
Infraorbitomeatal Line (IOML): Known as Reid's base line or the line of Frankfurt, it connects the infra-orbital point (below the eye) to the EAM.
-
Angle Difference Between OML and GML: There is an approximate 8-degree angle difference between the OML and GML, highlighting their distinct orientations.
-
Angle Difference Between OML and IOML: An average angle difference of 7 degrees exists between the OML and IOML, indicating differing anatomical reference points.
-
Angle Difference Between IOML and AML: The IOML and Acanthiomeatal line (AML) demonstrate an average angle difference of 15 degrees, reflecting variations in positioning references for skull imaging.
-
Acanthiomeatal Line (AML): This line extends from the acanthion (area between the nostrils) to the EAM, providing another reference point for skull positioning.
-
Interpupillary Line (IPL): Joins the centers of the pupils, serving as an important alignment guide in various imaging techniques.
-
Mentomeatal Line (MML): A line between the mental point (the midpoint of the mandible or chin) and the EAM, used in positioning for imaging studies.
-
Lips to Meatal Line (LML): Extends from the junction of the lips to the EAM, providing another positioning reference for radiography.
-
Glabelloalveolar Line: Connects the glabella to a point on the anterior aspect of the alveolar process of the maxilla, aiding in anatomical orientation.
-
Auricle Line: Perpendicular to the anthropological baseline, this line passes through the EAM, serving as a vital reference in skull positioning.
