Micrognathia

Micrognathia is insufficient development of the lower jaw, which is smaller or more set back than normal and changes the harmony of the face and the relationship between the teeth.

How it presents: It can show up as a small chin, a misaligned bite, and, in some cases, difficulty feeding or breathing, especially when it is present from birth.

Origin: Sometimes it is part of congenital syndromes and other times it is due to problems with bone growth during childhood.

Who treats it? It is best evaluated by specialists in otolaryngology together with maxillofacial surgery, depending on the impact on breathing, feeding, or the bite. When there is a notably small chin or associated problems, it is worth seeking a professional opinion to guide the next steps.
