Micrognathism, also called micrognathia, strawberry chin, hypognathia[1] or hypogthathism, is a condition where the jaw is undersized. It is also sometimes called "mandibular hypoplasia".[citation needed] It is common in infants,[citation needed] 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.[2] It can also, both in adults and children, make intubation difficult, either during anesthesia or in emergency situations.

Causes[edit]

While not always pathological, it can present as a birth defect in multiple syndromes including:

Diagnosis[edit]

It can be detected by the naked eye as well as dental or skull X-Ray testing.[citation needed]
