Triangular Face

Understanding face related symptoms and features

Symptoms may affect multiple parts of the body. Understanding which part of the body a symptom affects can help us to better understand the potential underlying causes of a symptom, including a rare disease or genetic syndrome.

The face contains the nose, eyes, and mouth, all of which are sensory organs. The face also displays emotions and feelings and plays a crucial role in communication. The face runs from the forehead at the top, to the chin at the bottom and encompasses everything in between.

Symptoms affecting the face can for the most part be seen with the naked eye. Although diagnosing a face related symptom may involve different tests and assessments, both subjective and objective.

Symptoms relating to the face may affect its structure, shape, and/ or function. Some features will affect just the appearance of the face while others may affect its ability to express emotions and to communicate non-verbally.

What is a triangular face?

When the contour of the face seems like a triangular shape, with the breadth at the temples and tapering to a narrow chin.

A triangular-shaped face may be one of the symptoms and distinct facial features of a genetic syndrome, including Leopard, Noonan, and Floating-Harbor syndromes.

What should I do next?

In some instances, a triangular face may be one of the features of a rare disease or genetic syndrome. In this case, fast, targeted genetic analysis can give you a more accurate diagnosis.

"Our road to a rare disease diagnosis was a 5-year journey that I can only describe as trying to take a road trip with no map. We didn’t know our starting point. We didn’t know our destination. Now we have hope."
