Micrognathism is a condition where the jaw is undersized. It is also sometimes called mandibular hypoplasia.[2] It is common in infants,[3][4] 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.[5] It can also, both in adults and children, make intubation difficult, either during anesthesia or in emergency situations.

Diagnosis
[edit]It can be detected by the naked eye as well as dental or skull X-Ray testing.[citation needed]
Treatments
[edit]Micrognathia can be treated by surgery and modified eating methods.[medical citation needed] Early detection of the problem and monitoring as the problems grows can help understand it better and find the most effective treatment procedure.
