Prevalensi Sumbing Bibir dan Langit-langit di RSUD Dr. Saiful Anwar Malang (1980-1989)

A retrospective study was performed on 34 cases of live births with palato-gnatoschizis among 31,598 births or among 387 life births with congenital malformations in "Dr Saiful Anwar" General Hospital in Malang, East Java, between 1980-1989. The prevalence of palato-gnatoschizis was 1.07 in 1000 births, or 8.78% of all congenital malformations. Palato-gnatoschizis is a relatively common congenital malformation with a relative high life expectancy. The monitoring system of births with palato-gnatoschizis has still to be developped properly. This study can be helpful to future in depth epidemiological research programmes on palato-gnatoschizis in other areas where higher prevalences are suspected.
