[Cleft lip and palate. The semantic conception for informatics. The Cleftor program]

The authors present the creation of a computed programme (Cleftor) which examines the terminology used in the pathology of cleft palates. The malformed anatomy is simplified and superimposed with embryological data. A classification which includes all possible malformation is used. Surgical treatment had also advanced, gestures practised in the past are reviewed and defined to give authors a common basis for discussion when it is time to appreciate results concerning such or such methods or techniques. Thanks to a strict control of facts; the programme gives another idea of the treatment and above all, of the results from that can be called chronic pathology. The Cleftor programme is also a means of communication creating perhaps a supplementary chance of success for a treatment that everyone admits to and considers as always difficult.
