What is Retrognathia?
Retrognathia is a condition affecting the lower jaw. The lower jaw is set further back than the upper jaw, giving what appears to be a large overbite.
In some cases it may be treated with orthodontic treatment and/or surgery.
Understanding skull-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 skull has several crucial functions: it cradles and protects the brain, supports the face, and forms the head. It is a bony structure made up of the mandible and cranium.
Symptoms affecting the skull can sometimes be seen with the naked eye, especially if they affect the shape, size, and structure of the head and face. Diagnosing a skull-related symptom may involve different tests and assessments, both subjective and objective.
A visibly smaller or recessed lower jaw gives the profile a “weak chin” appearance.
The mandible appears underdeveloped or positioned further back, altering the lower facial dimensions.
What should I do next?
In some instances, retrognathia may be one of the features of a rare disease or genetic syndrome. To find out if someone with Retrognathia, may be due to a genetic syndrome, it is important to have a consultation and evaluation with a clinical genetic specialist. Specialists may also suggest specific genetic testing or other types of tests to help reach a diagnosis. FDNA’s AI technology can help speed up the diagnostic process by analyzing facial features and other health information.
