Mental development in infants with cleft lip and/or palate

Area of Science:

• Pediatric developmental psychology
• Craniofacial anomaly research

Background:

• Cleft lip and/or palate (CLP) affects facial structure and can impact child development.
• Understanding developmental trajectories in infants and toddlers with CLP is crucial for early intervention.

Purpose of the Study:

• To investigate the mental development of infants and toddlers diagnosed with cleft lip and/or palate (CLP).
• To identify potential risk factors and developmental patterns in this population.

Main Methods:

• Retrospective analysis of developmental scores (Mental Development Index - MDI) from the Bayley Scales of Infant Development.
• Cross-sectional and longitudinal analyses were conducted on children aged 4 to 36 months.
• Participants were categorized into four diagnostic groups: cleft lip only (CL), cleft lip and palate (CLP), cleft palate only (CP), and Pierre Robin Sequence.

Main Results:

• Mean MDI scores were within the average range but showed a significant decrease with age in both cross-sectional and longitudinal samples.
• Significant differences in MDI scores were observed among the diagnostic groups, with CL infants scoring highest and Pierre Robin Sequence infants scoring lowest.
• Early perceptual-motor development in the first year of life predicted later developmental status at age 2.

Conclusions:

• A higher-than-expected number of children with CLP may be at risk for developmental problems, particularly during their second year of life.
• Early identification of delays in perceptual-motor skills during infancy is critical for identifying children at greatest risk for developmental challenges.
