title: Classification, recording, and cleft palate surgery at the Uppsala Cleft Palate Centre.
abstract: This paper describes the classification system, method of recording, and surgical techniques used in Uppsala for children with isolated cleft palate. The classification is based on the system described by Kernahan and Stark and the more detailed system described by the American Cleft Palate Association. Separation of the hard palate into thirds, and into right and left sides, assures a detailed description of the cleft, and separates small morphological differences. The longitudinal registration system was introduced into the Uppsala Cleft Palate Centre in 1967. After the initial recording at the time of primary surgery, it is repeated at 5, 8, 11, 14, 17, and 20 years. By emphasising the therapeutic aspects of various stages of growth, it has been possible to limit the recording to once every third year. This has resulted in an important reduction in the dose of radiation without compromising the reliability of the results. Children born before 1975 had clefts of both the soft and hard palate closed at 18-24 months in a one-stage procedure. For children born in 1975 and later a two stage technique has been used, while clefts limited to the soft palate only have been closed entirely in the first operation. At first, the soft palate cleft was closed at 18 months of age and the hard palate at 4 to 5 years. The timing was changed in several steps to the present soft palate closure at 6 months and hard palate closure at 2 years of age.
