Low-set ears are defined as the outer ears being positioned two or more standard deviations lower than the population average. [1] Clinically, if the point at which the helix (curved upper part) of the outer ear meets the cranium is at or below the line connecting the inner canthi of eyes (the bicanthal plane), the ears are considered low set ...
Microcephaly deafness syndrome is an extremely rare genetic disorder which consists of microcephaly, congenital hearing loss, mild intellectual disability, speech delay, low height, and facial dysmorphisms (such as low-set cup-shaped ears, protruding lower lips, micrognathia, epicanthal folds, drooping lower lip, and a rather big distance between both eyebrows).
In Saethre–Chotzen syndrome, the ears may be low set, posteriorly rotated, have other minor anomalies and there may be a presence of a conductive hearing loss or a mixed hearing loss (Perterson-Falszone, 2001). Hearing loss in this group can also be caused by middle ear disease when a cleft palate is present. [1]
They all had long and uneven facial features, low-set hairlines, short fingers, and webbing between the second and third fingers and between the second, third, and fourth toes. A year later in 1932, F. Chotzen, a German psychiatrist , described a father and his two sons as having very similar characteristics as the mother and her daughters, as ...
For low frequencies, it behaves similarly to a reflector dish, directing sounds toward the ear canal. For high frequencies, however, its value is thought to be more sophisticated. While some of the sounds that enter the ear travel directly to the canal, others reflect off the contours of the pinna first: these enter the ear canal after a very ...
Minor physical anomalies (MPAs) are relatively minor (typically painless and, in themselves, harmless) congenital physical abnormalities consisting of features such as low-set ears, single transverse palmar crease, telecanthus, micrognathism, macrocephaly, hypotonia and furrowed tongue.
In March, a mother was horrified to find a pedophile symbol on a toy she bought for her daughter. Although the symbol was not intentionally placed on the toy by the company who manufactured the ...
The outer ear, external ear, or auris externa is the external part of the ear, which consists of the auricle (also pinna) and the ear canal. [1] It gathers sound energy and focuses it on the eardrum ( tympanic membrane ).
