What causes condylar hypoplasia?

What causes condylar hypoplasia?

Acquired condylar hypoplasia happens when a person is not born with a small condyle but they sustain an injury during their growth which leads to this condition. The injury causes stop of growth in the condyle, resulting in a smaller condyle. The type of injuries that can happen are most traumatic in nature.

Is retrognathia the same as micrognathia?

Both anomalies in the development of the fetal jaw are different. Retrognathia implies a receding chin with a good prognosis if isolated. Micrognathia is a hypoplastic mandible, generally associated with retrognathia and mostly associated with other malformations, chromosomal abnormalities, and syndromes.

What is TMJ syndrome?

Temporomandibular Joint (TMJ) disorders are conditions affecting the jaw joints and surrounding muscles and ligaments. It can be caused by trauma, an improper bite, arthritis or wear and tear. Common symptoms include jaw tenderness, headaches, earaches and facial pain.

When does TMJ develop in utero?

2. The critical time area in the formation of the human temporomandibular joint is from the eighth to the tenth weeks of fetal life. During this 2 week period proliferation and histodifferentiation of the embryonic mesenchyme take place and the condyle of the mandible assumes its mature morphologic pattern.

How rare is condylar hyperplasia?

It is estimated that about 30% of people with facial asymmetry express condylar hyperplasia….

What causes small jaw?

It mainly occurs in children who are born with certain genetic conditions, such as trisomy 13 and progeria. It can also be the result of fetal alcohol syndrome. In some cases, this problem goes away as the child’s jaw grows with age. In severe cases, micrognathia can cause feeding or breathing problems.

Can braces fix Retrogenia?

There are a few causes of retrognathia. Treatment usually includes orthodontic appliances, braces and hardware, or surgery. In mild cases, no treatment may be needed.

What causes Retrognathia?

Because of the condylar portion of the growth of the mandible, temporomandibular trauma can restrict growth. Any blow to the chin or lower face, if severe enough, can cause this type of growth pattern and result in retrognathia and is worth asking about during a history.

Is TMJ hereditary?

TMJ symptoms such jaw pain, headaches or migraines or mysterious muscle stiffness, can be passed down from generation to generation. Because TMJ can be hereditary, anyone is susceptible.

How do you fix condylar hyperplasia?

Treatment usually includes condylectomy during the period of active growth. If growth has stopped, orthodontics and surgical mandibular repositioning are indicated. If the height of the mandibular body is greatly increased, facial symmetry can be further improved by reducing the inferior border of the mandible.
