Beyond Pierre Robin sequence.

The label Pierre Robin sequence is given to infants presenting with a triad of specific congenital anomalies: micrognathia, glossoptosis, and cleft palate. However, this label should be considered the first, not the final, step in the diagnostic process. In approximately 80 percent of newborns with Pierre Robin sequence, the triad of anomalies is part of an underlying genetic condition. This article reviews the variable etiologies of and general clinical considerations for Pierre Robin sequence. To illustrate how clinical management might vary based on the identification of an underlying condition, three case examples of neonates with Pierre Robin sequence and different underlying genetic conditions are presented.
