Micrognathism (also Micrognathia or snoffiness) 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 (Hong). It can also, both in adults and children, make intubation difficult, either during anesthesia or in emergency situations.
