Pronunciation: [pˈɔːɹi͡ən] (IPA) 
The word "porion" is spelled /pɔːriən/, with the stress on the first syllable. The phonetic symbols /p/, /ɔː/, /r/, /i/, /ə/, and /n/ represent the sounds that make up the word. The /p/ sound is a voiceless bilabial plosive, the /ɔː/ sound is a mid-back rounded vowel, the /r/ sound is an alveolar trill, the /i/ sound is a high front unrounded vowel, the /ə/ sound is a central mid vowel, and the /n/ sound is a voiced alveolar nasal.
Porion is a term with multiple definitions in various fields. In anatomy, specifically in craniofacial morphology, porion refers to a specific landmark located on the outermost edge of the ear canal. It lies at the intersection of the line connecting the external auditory meatus and the superior border of the external ear canal. This anatomical point is commonly used to determine the anatomical position of the skull for measurements and comparisons in anthropological studies, particularly in assessing the shape and size of the cranium.
In addition to its anatomical meaning, porion also has an architectural definition. In architecture, particularly in reference to vertical plane panels, a porion is a decorative or ornamental capital situated at the topmost part or crown of a column or pilaster. It serves as an aesthetically pleasing transition between a column or pilaster and the entablature or architrave.
Furthermore, porion has another usage in the field of audiology. It is a term used to refer to a specific temporal bone landmark relevant to the measurement and fitting of hearing aids. It is located at the point where the external ear canal meets the outer prominence of the ear. Knowledge of the porion in audiology is essential in ensuring proper alignment and fit of hearing aids for optimal sound delivery and comfort for the wearer.
Overall, the term "porion" pertains to different landmarks or structures in distinct disciplines such as anatomy, architecture, and audiology, each with its own specialized meaning and application.
The word "porion" comes from the Latin word "porus", which means "pore" or "hole". In anatomy, a "porion" specifically refers to a small depression on the skull located just above the external auditory meatus (ear canal). This term is commonly used in anthropology and forensic science when studying cranial measurements and identifying landmarks on human skulls.
