Revisiting of the facial cleft classification

Craniofacial cleft deformity is a partial or total defect of craniofacial tissues. Most craniofacial malformations are identified by their appearance. The severity of this deformity can range from slight skin excavation, hair loss, to wry mouth, skewed eyes, and absence of nose and face. The majority of the classification systems are mainly clinical or anatomical. In 1976, Tessier first emphasized the relationship between soft tissues and the underlying bone stating that “a fissure of the soft tissue corresponds, as a general rule, with a cleft of the bony structure.” He introduced a cleft numbering system around the orbit from 0 to 14 depending on its relationship to the zero line. In this paper, we revisited classification system of craniofacial cleft focusing on Tessier’s classification system with other updates.
