Macrognathia

Macrognathia is a medical term that describes a noticeable increase in the size of one jaw compared to the other. This usually occurs with the lower jaw becoming larger than the upper jaw. This can be caused by various reasons such as genetic factors, injury, tumors or other medical conditions.

One of the most common causes of macrognathia is Pierre-Robin syndrome, which is characterized by hypertelorism (increased distance between the eyes), micrognathia (small lower jaw), and pharyngeal problems. This syndrome can lead to serious breathing and feeding problems if not detected and treated promptly.

Another cause of macrognathia may be gigantism, which results from excess growth hormone secretion during childhood or early adolescence. This condition can lead to various medical problems such as arthritis, diabetes and heart problems.

The diagnosis of macrognathia can be made by visual inspection and examination of the patient. Additional tests, such as X-rays or CT scans, may be done to evaluate the extent of jaw enlargement and determine the cause.

Treatment for macrognathia depends on the cause of its occurrence. In some cases, such as Pierre-Robin syndrome, surgery may be necessary to correct the abnormality. In other cases, treatment may include the use of dentures or other devices to improve jaw function.

Overall, macrognathia is a serious medical condition that can lead to a variety of breathing, eating, and overall health problems. If you notice an increase in the size of your jaw, see your doctor for diagnosis and treatment. Your doctor will be able to determine the cause of macrognathia and recommend the best treatment for your case.

Macrognathia or macrognathia is a developmental anomaly of the maxillofacial region, manifested by a noticeable increase in the size of the lower jaw compared to the healthy upper jaw.

Q86.8. Gnathic characteristics

Macrognathia is not an independent pathology, but can be a symptom of various types of disorders that can affect the degree of development of the lower jaw and disruption of a number of functions of bite and speech. Patients with such a deviation of the jaw area can contact an orthodontist to find out the causes of the problem and eliminate it, which in turn will improve the person’s quality of life.
