Triangular Face

Understanding face related symptoms and features




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.
