Micrognathism is a condition where the jaw is undersized. It is also sometimes called mandibular hypoplasia.{{Cite journal |last1=Hassani |first1=Mohammad-Esmaiil |last2=Karimi |first2=Hamid |last3=Hassani |first3=Hosein |last4=Hassani |first4=Ali |date=2014-01-01 |title=Bilateral mandibular distraction in micrognathism or hypoplasia of mandible, hazrat fatemeh hospital |url=https://linkinghub.elsevier.com/retrieve/pii/S2221618914600640 |journal=Journal of Acute Disease |volume=3 |issue=4 |pages=296–299 |doi=10.1016/S2221-6189(14)60064-0 |issn=2221-6189|doi-access=free }} It is common in infants,{{Cite journal |last1=Cang |first1=Zhengqiang |last2=Cui |first2=Jiangbo |last3=Pei |first3=Jiaomiao |last4=Wang |first4=Zheng |last5=Du |first5=Yichen |last6=Mu |first6=Siqi |last7=Dou |first7=Wenjie |last8=Fan |first8=Xing |last9=Zhang |first9=Xi |last10=Li |first10=Yang |date=2023-04-12 |title=Prenatal diagnosis of micrognathia: a systematic review |journal=Frontiers in Pediatrics |language=English |volume=11 |doi=10.3389/fped.2023.1161421 |doi-access=free |issn=2296-2360 |pmc=10130438 |pmid=37124181}}{{Cite journal |last1=Berger |first1=Jessica A. |last2=Nelson |first2=Olivia |last3=Staben |first3=James |last4=Javia |first4=Luv R. |last5=Simpao |first5=Allan F. |last6=Khalek |first6=Nahla |last7=Oliver |first7=Edward R. |last8=Adzick |first8=N.
