Robin Sequence: More Than a Receding Chin
By John Mulliken, MD, Director, Craniofacial Centre, Boston Children’s Hospital
Children born with Robin sequence (named for an early 20th century French physician; pronounced row-BAN) have a lower jaw that is smaller than normal (micrognathia) or set back from the upper jaw (retrognathia).
Robin sequence begins with a lower jaw that is either too small or is set back from the upper jaw. This causes the tongue to be pushed backward in the throat, where it can flop back and block the airway. Most infants with Robin sequence also have a cleft palate.
