## Congenital[edit | edit source]

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.[citation needed]

## Acquired[edit | edit source]

Microstomia can occur as a result of scarring due to many conditions. It is seen as complication of facial burns.[1] It can also be a feature of systemic scleroderma.[2]
