The Pterion Is An Important Craniometric Point For Both Anthropological And Radiological Investigations.

Pt is an essential landmark for most anterolateral cranial procedures and the pterional craniotomy is centered over this point. Cranium dimensions differ according to racial, geopraphic, ethnic and nutritional factors. It lies at the meeting of four bones;

Craniometric Landmarks (Or Craniometric Points) Have Been Used In Anthropology Since The Xix Century.

The aim of this study was to verify the presence of sexual dimorphism in the brazilian population by craniometric analysis; The basion (ba) and prosthion (pr). Piriform aperture (pa) and nasal bone (nbs) are important structures that contribute to the formation of the nose.

In Rare Cases, The Determination Of The Position Of Basion.

Nasion is located at the point of intersection. A landmark on the skull from which craniometric/ cephalometric measurements can be taken are craniometric / cephalometric points To identify the most reliable measurements and to propose a.

The Point Where The Sagittal Suture Meets The Coronal Suture Anteriorly.

Technique used to measure the skull and determine human characteristics. Is there a difference in the cranial distances measured. This study will shed light on the question:

Indeed, The Pt Stands Above The Anterior Branch Of The Middle.

For increased clarity, some landmarks are not presented (glabella, prosthion, anterior nasal spine, basion, sella, and bregma). This point lies exactly opposite the. To record the raw data for geometric morphometrics analyses following the criteria of bookstein for landmark data (bookstein, 1991) (fig.1), a map of 15 anatomical landmarks.
