TOPS is a trial to find the best age at which to repair a cleft palate.
558 infants with an isolated cleft palate have been recruited from cleft palate centres across the UK, Scandinavia and Brazil. Babies participating in the trial received Surgery using the same technique (Sommerlad technique) and were randomly assigned to have their Surgery when they were either aged 6 months or 12 months. There was a 50:50 chance of infants being in either group.
After Surgery, children taking part in the TOPS trial are being followed up at age 12 months, 3 years and 5 years when speech, hearing and physical development are being reviewed.
The main objective of this trial is to determine whether the timing of the cleft palate Surgery has an influence on speech development.
