Micrognathia

Micrognathia is a condition in which one of the jaws (most often the lower) is abnormally small.

The cause of micrognathia is disturbances in the development of the lower jaw in the early stages of embryogenesis. As a result, the lower jaw does not reach normal size.

Micrognathia can be an isolated defect or part of a syndrome, for example, Pierre Robin syndrome, Noonan syndrome and others.

The main symptoms of micrognathia:

  1. Reduced chin
  2. Difficulty opening the mouth and chewing
  3. Malocclusion
  4. Facial bone deformity
  5. Breathing and speech disorders

Diagnosis of micrognathia is based on clinical examination and skull radiography.

Treatment includes surgical methods - osteotomy and bone grafting of the lower jaw. Children with micrognathia often require orthodontic treatment.

Early recognition and treatment of micrognathia is essential for the normal development and functioning of the maxillofacial system.



Micrognathia is a condition in which the upper jaw is unusually small in size compared to the lower jaw. This can be caused by various factors such as genetic abnormalities, injury, infection or disease.

Symptoms of micrognathia may include:

- Small mouth;
– Incorrect bite;
– Problems with speech;
– Difficulty chewing and swallowing.

Treatment for micrognathia may involve surgical correction, which may include increasing the size of the upper jaw and correcting malocclusions. Orthodontic appliances and exercises may also be used to strengthen the muscles and improve jaw function.

Micrognathia can cause serious health problems such as poor posture, breathing and digestive problems, and psychological problems. Therefore, it is very important to promptly consult a specialist for diagnosis and treatment.

Overall, micrognathia is a serious condition that can lead to a variety of health problems. However, timely consultation with a specialist and proper treatment can help improve the quality of life and prevent further complications.



Micrognathia is a condition where one of the jaw arches is small in size compared to the other. Typically this pathology occurs in the upper jaw. The phenomenon is typical for men about 20% more than for women. This anatomical condition may be temporary or permanent. However, in a child, deviation in the size of the jaw arch is usually temporary. In adults, micrognathia occurs due to abnormal bone growth in the maxillofacial area. At the same time, the size of the jaw does not correspond to normal values ​​for a person.



Micrognathia: What is it and how does it affect a person? Micrognathia is an abnormal condition in which a person has one of their jaw bones that is small in size (as opposed to normal). In most cases, this pathology is observed in the upper jaw, although in some cases there may be a slight reduction in the lower jaw. There are many reasons for the occurrence of micrognathia, including various diseases such as rickets, infectious diseases (for example, rubella), traumatic brain injury, facial paralysis, etc. But the most common cause is a congenital genetic defect that develops during fetal development.

Symptoms The first signs of micrognathia are problems with speech. It becomes difficult for a person to pronounce individual sounds (letters) or words as a whole. In addition, as the pathology develops, a narrowing of the upper jaw and protrusion of the upper lip forward are observed, which leads to disruption of the correct bite and closure of the teeth. A patient suffering from micrognathia may experience pain in the lower jaw and difficulty chewing, especially when eating solid foods. There is also a decrease in the height of the upper teeth, which creates difficulties in communication and limits the ability to perform certain medical procedures (for example, professional teeth cleaning).

**Consequences of micrognathia** Micrognathia has a significant impact on a person’s appearance, as well as on his psycho-emotional state. Being in society, a person may experience a feeling of discomfort and insecurity due to such features of appearance,
