Microstomia ({{ety|el|micro-|small||-stomia|mouth}}) is the medical condition of an abnormally small mouth.

Congenital

It is a feature of many craniofacial syndromes, including Freeman–Sheldon syndrome and Sheldon-Hall syndromes (or distal arthrogryposis multiplex congenita). It may present with whistling-face feature, as well, as in Freeman-Sheldon syndrome. In this syndrome, it impairs alimentation and may require repeated oral surgeries (called commissurotomy) to improve function.{{cn|date=March 2019}}

Acquired

Microstomia can occur as a result of scarring due to many conditions. It is seen as complication of facial burns.{{cite book |title=Hagberg and Benumof's Airway Management |publisher=Elsevier |pages=608-639 |edition=4e}}
