title: Mental development in infants with cleft lip and/or palate.
abstract: OBJECTIVE
  Investigated mental development in infants and toddlers with cleft lip and/or palate (CLP).
  
  
  METHODS
  This was a retrospective analysis of developmental scores on qualified children between 4 and 36 months of age. Cross-sectional analysis included children in four age groups (6, 12, 18, and 24 months); longitudinal analysis included children at mean age 9.1 (range = 4 to 15) months at Time 1 and 24 months (range = 16 to 36) at Time 2.
  
  
  METHODS
  Cross-sectional analysis included 180 children (59% male participants) in four diagnostic groups (cleft lip only [CL], cleft lip and palate [CLP], cleft palate only [CP], and Pierre Robin). The longitudinal sample included 85 children (64% male children) in the same diagnostic groups.
  
  
  METHODS
  Mental Scale (MDI) of the Bayley Scales of Infant Development.
  
  
  RESULTS
  Mean MDIs were in the average range but decreased significantly between youngest and oldest groups in both cross-sectional (F(3,179) = 4.9, p<.01) and longitudinal samples (F(1,84) = 6.87, p<.01). There was a significant difference among cleft types (F(3,179) = 3.5, p<.025). Infants with CL obtained the highest scores, and infants with Pierre Robin Sequence obtained the lowest. Perceptual-motor development in the first year of life was predictive of developmental status at age 2.
  
  
  CONCLUSIONS
  The number of children with CLP who may be at risk for developmental problems during the second year of life is greater than would be expected. Children at greatest risk may demonstrate early delays in acquisition of perceptual-motor skills during the first year of life.
