Cognitive and psychosocial development of children with Pierre Robin sequence

Area of Science:

• Pediatric neurology
• Developmental psychology
• Craniofacial anomalies

Background:

• Pierre Robin sequence (PRS) is a congenital condition characterized by mandibular hypoplasia, glossoptosis, and cleft palate.
• The etiology of cognitive impairment in PRS is debated, with theories suggesting either primary brain involvement or secondary effects of chronic upper airway obstruction (UAO).

Purpose of the Study:

• To investigate the cognitive and psychosocial outcomes in children with PRS treated for UAO in infancy using a pre-epiglottic baton plate.
• To determine if early UAO treatment in PRS prevents cognitive impairment.

Main Methods:

• A cohort of 34 children with PRS (aged 4-11 years) and 34 healthy controls were assessed using the Kaufman-Assessment Battery for Children (K-ABC) and a self-concept inventory.
• Parental ratings of emotional and behavioral problems were collected. Statistical analyses included multi- and univariate analyses of covariance, controlling for relevant covariates.

Main Results:

• Children with PRS performed significantly poorer on the K-ABC compared to healthy controls, although their cognitive development was within the normal reference range.
• No significant differences were observed in self-concept, emotional, or behavioral problems between the PRS group and the control group.

Conclusions:

• Early treatment of UAO in infancy with a pre-epiglottic baton plate in non-syndromic PRS did not fully normalize cognitive performance as measured by the K-ABC.
• While children with PRS showed lower cognitive scores than controls, the results did not indicate a major cognitive impairment, suggesting UAO may play a role but is not the sole determinant of cognitive outcome.
