What is a common diagnostic sign of Pierre Robin Syndrome?

A common diagnostic sign of Pierre Robin Syndrome is characterized by the presence of a small jaw, also known as micrognathia, combined with a normal-sized or even large tongue. This condition is significant because the small jaw can lead to a posterior positioning of the tongue, which may obstruct the airway and cause breathing difficulties. This airway obstruction is a hallmark of the syndrome and can contribute to associated feeding problems and other complications.

Pierre Robin Syndrome often presents in a triad of symptoms including micrognathia, glossoptosis (the backward placement of the tongue), and cleft palate, although not all individuals will necessarily have a cleft palate. The physical manifestation of a small jaw is critical for diagnosing the syndrome, making it a key diagnostic feature.
