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 ...
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 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]
Facial features include widely spaced eyes, light-colored eyes, low-set ears, a short neck, and a small lower jaw. [1] Heart problems may include pulmonary valve stenosis. [1] The breast bone may either protrude or be sunken, while the spine may be abnormally curved. [1] Intelligence is often normal. [1] Complications of NS can include leukemia ...
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 ...
Low-set ears are the most common cranial dysmorphism seen in 3C syndrome, and ocular coloboma is the least common of the non-concurrent symptoms (cleft lip co-occurring with cleft palate is the least common). [5] Cranial dysplasias associated with 3C syndrome are also reflected in the brain.
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).
Not every case has had craniosynostosis however. Other parts of the skull may be malformed as well. This will usually cause an abnormally shaped head, wide-set eyes, low set ears and flattened cheekbones in these patients. About 5 percent of affected individuals have an enlarged head (macrocephaly).
