Definition

Noun: - The craniometric point on either side at the apex of the lower jaw: In anatomy and craniometry, the gonion is a specific, measurable point located at the most outward and downward projecting point of the angle of the mandible (lower jawbone). It is used as a landmark for measurements of the skull.

Usage

The term "gonion" is a highly specialized anatomical term. It is used almost exclusively in professional, academic, or clinical contexts such as anthropology, forensic science, dentistry, orthodontics, and maxillofacial surgery.

Examples

  • The forensic anthropologist measured the distance from the gonion to the menton to analyze the jaw's proportions.
  • In cephalometric analysis, the position of the gonion is crucial for assessing facial growth and planning orthodontic treatment.
  • The study compared the gonion angle between different population groups.

Advanced Usage

• "Gonial angle": This is a common related term referring to the angle formed at the gonion, typically between the body and the ramus of the mandible.
  • A patient with a more obtuse gonial angle may have a different facial profile.

Variants and Related Words

• Gonial (adj): Pertaining to the gonion or the angle of the mandible.
