title: Perspectives on craniofacial asymmetry. IV. Hemi-asymmetries.
abstract: Hemi-asymmetries discussed here include: 1) hemihyperplasia which may affect either one tissue such as bone with secondary regional consequences or multiple tissues on a primary basis such as "hemihypertrophy"; 2) hemihypoplasia which may also affect one tissue such as bone with secondary regional consequences or multiple tissues on a primary basis such as in hemifacial microsomia; 3) hemiatrophy, the quintessential craniofacial disorder being Romberg syndrome; and 4) miscellaneous conditions such as Bencze syndrome and hemimaxillofacial dysplasia.
