Porion
Anatomical landmark in the human skull
The porion is an important anatomical landmark located on the human skull. It is defined as the uppermost point on the external opening of the external acoustic meatus, which is the ear canal. The porion is used in various fields such as anthropometry, dentistry, and orthodontics for craniofacial measurements and analysis.
Anatomical Location[edit | edit source]
The porion is situated on the temporal bone of the skull. It is specifically located at the superior margin of the external acoustic meatus. This point is often used as a reference in cephalometric analysis, which is a diagnostic tool used in orthodontics to assess the relationships between dental and skeletal components of the head.
Significance in Cephalometry[edit | edit source]
In cephalometric analysis, the porion is used as a reference point to establish the Frankfort horizontal plane, which is a standard plane of reference in craniofacial measurements. The Frankfort horizontal plane is defined by a line passing through the porion and the orbitale, which is the lowest point on the inferior margin of the orbit. This plane is used to orient the skull in a consistent manner for diagnostic and treatment planning purposes.
Applications in Anthropology[edit | edit source]
In the field of anthropology, the porion is used to study human evolution and variation. Measurements involving the porion can help anthropologists understand differences in skull shape and size among different populations and species. It is also used in forensic anthropology to assist in the identification of skeletal remains.
Clinical Relevance[edit | edit source]
In clinical settings, accurate identification of the porion is crucial for orthodontic diagnosis and treatment planning. It helps in assessing the growth and development of the craniofacial complex and in planning surgical interventions when necessary.
