What is unilateral aural atresia?

What is unilateral aural atresia?

Aural atresia is the lack of a fully developed ear canal, eardrum, middle ear space, and ear bones. Aural atresia is often accompanied by microtia, a congenital deformity of the outer ear. Microtia and atresia may be unilateral (one ear) or bilateral (both ears).

What causes aural atresia?

Aural atresia occurs in 1 in 10,000 live births. It is more common in boys. It more commonly only effects one ear. Although the exact cause is not known, when the fetus is developing something causes the ear to stop growing before it is complete.

How is aural atresia diagnosed?

Congenital aural atresia requires prompt diagnosis, genetic counselling and an early assessment of hearing. In bilateral atresia, early amplification with a bone conduction hearing aid is essential for proper speech development.

What is congenital atresia?

Congenital atresia is the maldevelopment or non-development of the ear canal. It can either occur on its own or along with other abnormalities involving the head and neck. It most commonly occurs on one side, but can occur on both sides. When it does occur on one side, it is usually on the right.

What is aural atresia and microtia?

Aural atresia is the absence of the ear canal. The outer ear and ear canal develop at the same time, which means that microtia and atresia are commonly found together. This causes a hearing loss (what is called a “maximal conductive loss”) because the sound waves cannot get through to the eardrum/inner ear.

Is aural atresia genetic?

► Population Genetics Congenital aural atresia is a rare anomaly, occurring in approximately 1 in 10,000 live births (Melnick et al., 1979).
