Prognathism refers to a condition where the jaw protrudes or extends beyond the upper portions of the face, resulting in a projecting jaw. This condition often results from genetic factors or skeletal discrepancies and can lead to functional and aesthetic concerns for the patient. In cases of prognathism, the lower jaw (mandible) may be positioned forward in relation to the upper jaw (maxilla), which is characteristic of the symptom described.

The significance of identifying prognathism is crucial in surgical settings, especially for orthodontic or maxillofacial surgical interventions where correction of the jaw position might be necessary. Recognizing this condition helps in planning appropriate treatments that could include surgical repositioning or orthodontic adjustments to improve facial harmony and function.
