The term "polus frontalis" is a scientific term used to refer to the frontal pole of the brain, which is located in the front of the cerebral cortex. The spelling of this word can be explained using IPA phonetic transcription as /ˈpoʊləs frɑnˈteɪlɪs/. The first syllable, "po", is pronounced with a long "o" sound, while the second syllable, "lus", rhymes with "bus". The last two syllables, "frontalis", are pronounced with the stress on the second syllable, and the "a" is pronounced as "ah".
Polus frontalis refers to a cephalometric landmark used in orthodontics and orthognathic surgery to assess and measure certain craniofacial structures. Specifically, it is a point on the frontal bone of the skull that serves as a reference for different reference planes and angles used in the evaluation and diagnosis of facial skeletal relationships.
Situated at the midpoint of the forehead, the polus frontalis is commonly used as a cephalometric reference point in various analyses of the skull. It aids in determining the position of the forehead, as well as the inclination and projection of the upper facial structures. The polus frontalis plays a crucial role when assessing facial balance and symmetry, particularly in relation to the middle and lower thirds of the face.
In orthodontic and orthognathic surgery treatments, cephalometric analyses are performed to diagnose and plan the management of malocclusions and dentofacial deformities. The polus frontalis is an important anatomical landmark that enables orthodontists and surgeons to assess and quantify the position and alignment of various craniofacial structures. By measuring angles and distances relative to the polus frontalis, professionals can formulate treatment plans and determine the extent of required surgical interventions to achieve optimal facial aesthetics and function.
Overall, the polus frontalis serves as a critical reference point in cephalometric analyses and plays a fundamental role in evaluating and diagnosing craniofacial discrepancies, facilitating precise treatment planning and execution.

The term "polus frontalis" is derived from two Latin words: "polus" and "frontalis".
1. Polus: The word "polus" in Latin means "pole" or "end". It is often used to indicate a fixed point or a region. In anatomy, it is used to refer to a specific region or point in a certain organ or body part.
2. Frontalis: The word "frontalis" is derived from the Latin word "frons", which means "forehead". It refers to the front part of the head or forehead region.
When combined, "polus frontalis" refers to the specific region or point on the forehead.
