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}}
It can also be a feature of systemic scleroderma.{{cite book |last1=Jameson |first1=J. Larry |title=Harrison's Principles of Internal Medicine |publisher=McGraw-Hill Education |pages=ch 353 |edition=20}}
