METOPIC Meaning and
Definition
-
Metopic is an adjective that describes a specific condition or characteristic related to the shape or structure of the skull. It specifically refers to the metopic suture, which is a fibrous joint that runs along the midline of the front part of the skull, separating the two frontal bones. This junction closes during infancy, typically around the age of 2 to 3 years, with the formation of a solid bone.
However, in some cases, the metopic suture remains open, a condition medically known as metopic synostosis or trigonocephaly. This results in a ridge or ridge-like shape along the forehead, creating a distinctive appearance. The metopic ridge may extend vertically from the top of the forehead to the center of the skull, giving it a triangular shape.
Metopic synostosis is a relatively rare condition, occurring in about 1 in 2,000 births. While the exact cause is not fully understood, it is believed to be a combination of genetic and environmental factors. In some cases, it may be associated with other craniofacial abnormalities or genetic syndromes.
Treatment for metopic synostosis usually involves surgical intervention, performed by a specialist such as a pediatric neurosurgeon or craniofacial surgeon. The goal is to release the fused bones, reshape the skull, and create a more symmetrical appearance. Early intervention is important to allow for optimal brain growth and development. Post-surgical care may involve the use of helmets or braces to support and shape the skull.

Common Misspellings for METOPIC
Etymology of METOPIC
The word "metopic" originates from the combination of two Greek roots: "meta", meaning "beyond" or "after", and "ōps", meaning "face" or "forehead". When combined, these roots form "metōpsis", which translates to "brow" or "forehead" in Greek. Over time, the word evolved and in English, it became "metopic". This term is commonly used in medical and anatomical contexts to describe a specific condition or feature related to the forehead or the metopic suture, which is the horizontal suture between the frontal bones of the skull in infants.
