Microtia is a congenital deformity where the auricle (external ear) is underdeveloped. A completely undeveloped auricle is referred to as anotia. Because microtia and anotia have the same origin, it can be referred to as microtia-anotia. [1] Microtia can be unilateral (one side only) or bilateral (affecting both sides).
The surgical option is cosmetic reconstruction of the external ear's normal shape and repair of the ear canal. In less severe cases, the reconstruction will be sufficient to restore hearing. In grades of anotia/microtia that affect the middle ear, the surgery with the use of a bone-anchored hearing aid (BAHA) will likely restore the hearing ...
Bronchial atresia is a rare congenital disease characterized by segmental or lobar emphysema and, in some cases, mucoid impaction. The exact cause of bronchial atresia is unknown; the lobar bronchi, subsegmental bronchi, and distal bronchioles develop in the fifth, sixth, and sixteenth weeks of fetal development, respectively.
This monkey, called Britches (born March 1985), was a stump-tailed macaque who was born into a breeding colony at UCR. He was removed from his mother at birth, had his eyelids sewn shut, and had an electronic sonar device attached to his head—a Trisensor Aid, an experimental version of a blind travel aid, the Sonicguide—as part of a three ...
A baby monkey struggles and squirms as it tries to escape the man holding it by the neck over a concrete cistern, repeatedly dousing it with water. In another video clip, a person plays with the ...
Freudenthal initially described these species in the genus Microtia in 1976 [1] (with reference to Microtus, a vole with similar teeth), but later the same scholar renamed the genus to Mikrotia in 2006, [2] since the name Microtia was already preoccupied by a butterfly genus named in 1864. [3]
Cryptotia is the condition where an ear appears to have its upper portion buried underneath the side of the head. The condition also involves underdeveloped scapha and antihelical crura . Cryptotia is also known as buried ear or hidden ear.
The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear.The adult human ear canal extends from the auricle to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.
