From Wikipedia, the free encyclopedia
Micrognathism (or Micrognathia) is a condition where the jaw is undersized. It is also sometimes called "Mandibular hypoplasia". It is common in infants, but is usually self-corrected during growth, due to the jaws increasing in size. It may be a cause of abnormal tooth alignment and in severe cases can hamper feeding.
[edit] Causes
While not always pathological, it can present as a birth defect in multiple syndromes including: fetal alcohol syndrome, congenital rubella, DiGeorge's Syndrome, Pierre Robin syndrome, Hallermann-Streiff syndrome, Trisomy 13, Trisomy 18, X0 syndrome (Turner syndrome), Progeria, Treacher Collins syndrome, Smith-Lemli-Opitz syndrome, Russell-Silver syndrome, Seckel syndrome, Cri du chat syndrome and Marfan syndrome.
[edit] Diagnosis
It can be detected by dental or skull X-Ray testing.
