Micrognathia in Newborns

Micrognathia in Newborns Abstract MICROGNATHIA is more common in newborns than suspected. This anomaly is frequently associated with cleft palate. It is defined as hypoplasia of the mandible.

Abstract

Abstract MICROGNATHIA is more common in newborns than suspected. This anomaly is frequently associated with cleft palate. It is defined as hypoplasia of the mandible. It is characterized by a small, receding chin that fails to maintain the tongue in a forward position. Affected infants can be expected to provide for themselves a sufficiently large oral cavity and forward tongue fixation at about 5 to 7 months. Until the oral cavity and tongue fixation occur, proper and immediate treatment is essential. An esthetically pleasing profile in adulthood usually can be expected in the moderate to mild forms of micrognathia. Feeding difficulty many times is attributed to the cleft palate when it is present. Micrognathia and glossoptosis are overlooked. The complications associated with micrognathia were described by Virchow1 and Maurice.2 Pierre Robin3 described a series of children with adenoid facies without adenoid enlargement. He noted that respiratory obstruction was References 1. Virchow, R., quoted by Eley, R.C., and Farber, S.: Hypoplasia of the Mandible , Amer J Dis Child 39:1167-1175 ( (June) ) 1930.Crossref 2.
