Ear tag
|
|
Ear tagCommon minor anomaly, a rudimentary tag of ear tissue, often containing a core cartilage, usually located just in front of the ear (auricle). Therefore also called preauricular tag. The presence of 2 or more minor anomalies in a child increases the probability that the child has a major malformation.
RELATED TERMS--------------------------------------
Anomaly
Deviation from normal.
Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.
Cartilage
A firm, flexible connective tissue. In vertebrates, the cartilage forms the skeleton in the early stages of development, after which it is largely replaced by bone. Some cartilage remains at the joints to give flexibility and support.
Anomalies
Birth defects; abnormalities.
Malformation
Abnormal or anomalous formation or structure; deformity.
SIMILAR TERMS--------------------------------------
Ear bones
The malleus, incus, and stapes.
Ear canal, self-cleaning
Most of the time the ear canals are self-cleaning, that is, there is a slow and orderly migration of ear canal skin from the eardrum to the outer opening. Old earwax is constantly being transported from the deeper areas of the ear canal to the opening where it usually dries, flakes, and falls out.
Ear cleaning (by a doctor)
When so much wax accumulates that it blocks the ear canal (and hearing), your physician may have to wash it out, vacuum it, or remove it with special instruments. Alternatively, your physician may prescribe ear drops what are designed to soften the wax (such as Cerumenex).
Ear cleaning (yourself)
Never put anything smaller than your elbow in your ear! Wax is not formed in the deep part of the ear canal near the eardrum, but only in the outer part of the canal. So when a patient has wax pushed up against the eardrum, it is often because he has been probing his ear with such things as cotton-tipped swabs (such as Q-Tips), bobby pins, or twisted napkin corners. Such objects only serve as ramrods to push the wax in deeper. Also, the skin of the ear canal and the eardrum is very thin, fragile and easily injured. The ear canal is more prone to infection after it has been whipped clean of the "good" coating type wax. In addition, we have seen many perforated eardrums as a result of these efforts.
Ear infection, middle (acute)
Acute middle ear infection, medically called acute otitis media is inflammation of the middle ear. Acute otitis media typically causes fluid in the middle ear accompanied by signs or symptoms of ear infection: a bulging eardrum usually accompanied by pain; or a perforated eardrum, often with drainage of purulent material (pus).
Ear piercing
The practice of using a needle or needle gun to make holes through the ear lobe or other parts of the ear for wearing jewelry. When done under hygienic conditions, there is little danger from ear piercing other than localized and transitory inflammation. Unhygienic conditions, handling the new piercing with unwashed hands, or the use of irritating jewelry can result in inflammation and/or infection. Infected ear piercings should be washed and then treated with antibiotic cream. One may choose to either allow the piercing to close or to use only non-irritating jewelry (usually gold or hypoallergenic plastic). The likelihood of inflammation and infection is greater for piercings that go through hard cartilage, as found on the side and top of the outer ear, than with the soft bottom lobe of the ear.
Ear pit
Tiny pit in front of the ear: preauricular pit. A minor anomaly of no great consequence in itself. More common in blacks than whites and in females than males. Can recur in families. The presence of 2 or more minor anomalies in a child increases the probability that the child has a major malformation.
Ear puncture
Puncture of the ear drum may be due to an accident for example when something is stuck into the ear. Or it may be due to fluid pressure in the middle ear. Today the ear drum is occasionally punctured on purpose with surgery. A surgically placed tiny incision (a myringotomy) is made in the eardrum. Any fluid, usually thickened secretions, is removed and an ear tube may be inserted.
Ear ringing
Together with other abnormal ear noises, ear ringing is medically called tinnitus. Tinnitus can arise in any of the four sections of the ear: the outer ear, the middle ear, the inner ear, and the brain. It can be due to many causes including ear infection, fluid in the ears, Meniere syndrome, medications such as aspirin and other nonsteroidal antiinflammatory drugs (NSAIDs), aging, and ear trauma (such as from the noise of planes, firearms, or loud music). In rare situations, tinnitus may reflect an aneurysm or an acoustic neuroma (a benign tumor on the acoustic nerve). Woodwind players are more likely to experience tinnitus than other orchestral players, probably because they usually sit just in front of the brass. If tinnitus persists and its cause is unknown, a hearing test (audiogram) should be done. Measures can be taken to lessen the intensity of tinnitus or to mask it.
Ear thermometer
A thermometer that registers body temperature via the ear canal.
Ear tubes
Formally known as tympanostomy tubes, ear tubes are small plastic tubes inserted into the eardrum (the tympanum) to keep the middle ear aerated for a prolonged period of time. To put the tubes in place, a myringotomy (a surgically placed tiny incision in the eardrum) is done. Any fluid, usually thickened secretions, will be removed. The ear tubes usually remain in place for 6 months to several years. Water should not be allowed to enter the ear canal while the tubes are in place. Eventually, they will move out of the eardrum (extrude) and fall into the ear canal. The doctor may remove the tube during a routine future office visit or it may simply fall out of the ear without the child realizing it.
Ear wax
A natural wax-like substance secreted by special glands in the skin on the outer part of the ear canal. It repels water, and traps dust and sand particles. Usually a small amount of wax accumulates, and then dries up and falls out of the ear canal carrying with it unwanted particles. Ear wax is helpful in normal amounts and serves to coat the skin of the ear canal where it acts as a temporary water repellent. The absence of ear wax may result in dry, itchy ears, and even infection. There are two types of ear wax: wet and dry. Most whites and blacks have the wet type while most Asians and Native Americans have the dry type. The gene for wet ear wax on chromosome 16 appears to predispose to breast cancer.

Ear, cauliflower
An acquired deformity of the external ear to which wrestlers and boxers are particularly vulnerable.
Ear, external
There are three sections of the ear. They are the external ear, the middle ear, and the inner ear. The external ear looks complicated but it is functionally the simplest part of the ear. It consists of the pinna or auricle (the visible projecting portion of the ear), the external acoustic meatus (the outside opening to the ear canal), and the external ear canal that leads to the ear drum. In sum, there is the pinna, the meatus and the canal. And the external ear has only to concentrate air vibrations on the ear drum and make the drum vibrate. The external ear is also called the outer ear.
