Mandibular Hypoplasia is a condition characterized by the underdevelopment of the lower jaw, or mandible. This can lead to a smaller chin and misalignment of teeth, affecting facial appearance and function. It may occur as an isolated condition or as part of syndromes like Treacher Collins syndrome. The causes of mandibular hypoplasia can include genetic factors, environmental influences, or developmental issues during pregnancy. Treatment options vary based on severity and may involve orthodontics, surgery, or other interventions to improve jaw function and aesthetics. Early diagnosis is important for effective management.
