Hemifacial Microsomia is a birth deformity affecting the bony skeleton and soft tissues of the craniofacial region. It is typically characterized by pronounced asymmetry of the face due to deficient growth of the lower jaw (mandible) on one side, deficient soft tissues of the face and underdeveloped ear (microtia).
Bony and soft tissue structures on one side of the face grow lesser than the other side. The affected side of the face appears disproportionately smaller than the other. Commonly affected are the lower jaw, eye, ear, facial nerve and cheek. The most significant of these deformities is that of the jaws, which when corrected, minimizes the entire deformity and makes the face look more symmetric.
