Hippocrates (400 BC) and Galen (150 AD) mention cleft lip, but not cleft palate in their writings. For centuries, perforations of the palate were considered to be secondary to syphilis, and cleft palate was not recognized as a congenital disorder until 1556, by Fanco. The first successful closure of a soft palate defect was reported in 1764 by LeMonnier, a French dentist. The first closure of the hard palate was performed in 1834 by Dieffenbach. In the 1930's, Kilner and Wardill independently developed the "pushback" procedure.
A cleft lip and palate is a type of birth defect that affects the top lip and the roof of the mouth (the palate). A cleft is an opening, or split, in either the lip or the palate, or sometimes in both.
Cleft lips and palates are sometimes part of a wider series of birth defects, but usually happen on their own.
