A group of abnormalities marked primarily by a very small lower jaw with a tongue that falls back and downward. The syndrome may include a high arched palate or cleft palate.
Causes, incidence, and risk factors
The specific causes of Pierre Robin syndrome are unknown; it can be part of many genetic syndromes. The lower jaw develops slowly over the first few months of fetal life but catches up over the first year after birth. Posterior placement of the tongue may cause choking episodes, feeding difficulty and breathing difficulties , especially while asleep.
Treatment
Infants must be kept prone (face down), which allows gravity to pull the tongue forward and keep the airway open. These problems abate over the first few years as the lower jaw grows and assumes a more normal size. In moderate cases, the patient requires placement of a nasopharyngeal airway (a tube placed through the nose and into the airway) to avoid airway blockage. In severe cases, surgery is indicated for recurrent upper airway obstruction . Tracheostomy is sometimes required. Feeding must be done very carefully to avoid choking and aspiration of liquids into the airways.
Expectations (prognosis)
Choking and feeding problems may go away spontaneously as the jaw grows. There is a significant risk of problems if the airway is not protected against obstruction.
Calling your health care provider
This condition is often apparent at birth. Call if choking episodes or breathing problems increase in frequency. Airway blockage may be indicated by a high-pitched, crowing noise when inhaling ( stridor ) or blueness of the skin ( cyanosis ). Also call if other breathing problems occur.
Prevention
Prevention of the syndrome is unknown. Treatment may reduce the number of episodes of breathing problems and choking .
