midface hypoplasia
Underdevelopment of the middle third of the face, creating a characteristic flat or retrusive appearance.
Full Definition
A craniofacial deformity characterized by underdevelopment or retrusion of the midface structures, including the maxilla, nasal bones, and zygomatic bones. This condition is commonly seen in syndromes such as Crouzon, Apert, and Pfeiffer syndromes, as well as in cleft-related deformities. Midface hypoplasia results in functional problems including breathing difficulties, malocclusion, and potential obstructive sleep apnea, often requiring surgical advancement procedures such as Le Fort osteotomies or distraction osteogenesis.
