What complex of congenital abnormalities is associated with Pierre Robin Syndrome?

1. High arched palate, receiving chin, natal teeth

2. Small mandible, protruding tongue, cleft palate

3. Large jaw, normal teeth, cleft lip

4. Overbite, small tongue, severe facial asymmetry

The correct answer is: Small mandible, protruding tongue, cleft palate

The complex of congenital abnormalities associated with Pierre Robin Syndrome includes a small mandible (micrognathia), a protruding tongue (glossoptosis), and a cleft palate. These abnormalities are interrelated and result from disruptions in the normal development of the jaw and palate during early fetal growth. In Pierre Robin Syndrome, the underdevelopment of the mandible can cause the tongue to be positioned more posteriorly, which may lead to airway obstruction, especially in newborns. The cleft palate often accompanies these features, presenting challenges with feeding and increasing the risk of aspiration. Recognizing this triad of symptoms is critical for assessment and appropriate management in affected individuals. The other options do not accurately represent the key components of Pierre Robin Syndrome. For instance, a high arched palate or natal teeth would not typically be associated with this syndrome. Instead, the hallmark features focus specifically on the small mandible, the positioning of the tongue, and the presence of a cleft palate.
