The incidence of cleft lip and palate deformities in the south-east of Scotland (1971-1990).
This retrospective study reports the incidence of infants born with the cleft lip and palate anomaly within the Edinburgh Cleft Units catchment area, between 1 January, 1971, and 31 December, 1990. The importance of accurate data collection for local, regional, and national data bases is discussed with reference to the recent CSAG report on cleft lip and palate services in the UK. Five-hundred-and-two cleft lip and palate patients were identified (291 males, 211 females). The incidence is reported as 1.4 per 1000 live births (1 in 711). Twenty-five per cent of clefts affected the primary palate, 45 per cent affected the secondary palate, and the remaining 30 per cent were clefts of both the primary and secondary palate. Overall, a higher percentage of males were affected (58 per cent males to 42 per cent females). Clefts of the secondary palate, however, were more common in females (56 per cent females to 44 per cent males). Data presented in this study is similar to that previously reported from UK centres. It is suggested the accuracy of the UK cleft lip and palate data collection needs to be improved. Prospective data collection in a standardized format carried out on a national basis has to be a priority as recommended by the CSAG report.
