Introduction to Cleft Lip Revision
Cleft lip with or without cleft palate occurs in about 1 out of 700 live births. The condition may affect either the right side, the left side, or both sides. The cleft may either be complete (the full vertical height of the lip) or incomplete. In most cases of cleft lip, there is an associated cleft of the palate. The cleft may cause difficulties with feeding, speech, breathing, dentition, and growth.
