What is maxillary hypoplasia?

Maxillary hypoplasia, which is also called maxillary deficiency, is the underdevelopment of bones in the upper jaw. This condition produces midfacial retrusion and creates the appearance of protuberance where the lower jaw juts forward.

What causes maxillary hypoplasia?

Maxillary hypoplasia, or maxillary deficiency, is an underdevelopment of the bones of the upper jaw. It is associated with Crouzon syndrome, Angelman syndrome, as well as fetal alcohol syndrome. It can also be associated with cleft lip and cleft palate. Some people could develop it due to poor dental extractions.

How is maxillary hypoplasia diagnosed?

Maxillary hypoplasia can be diagnosed by a CT scan of the facial bones showing a shift in the position of the medial processes of the maxilla, resulting in narrowing of both anterior and posterior parts of the nasal cavity.

What is facial hypoplasia?

More localized anomalies, such as Binder syndrome, also known as maxillonasal dysplasia, refers to congenital maxillary hypoplasia.

Is maxillary hypoplasia genetic?

Maxillofacial dysostosis is inherited as an autosomal dominant trait. Genetic diseases are determined by the combination of genes for a particular trait that are on the chromosomes received from the father and the mother.

What is a maxilla?

What is the cause of hypoplasia?

Hypoplasia affects the development of a tissue or organ due to a lack of cell growth. Conditions involving hypoplasia are typically the result of a problem at birth that causes too few cells in a tissue or organ. This lack of cells can cause problems with the functioning of the tissue or organ.

What causes cerebral hypoplasia?

What is the function of the maxillary?
