| ear ringing | Together with other abnormal ear noises, ear ringing is medically called tinnitis. Tinnitus can arise in any of the four sections of the ear: the outer ear, the middle ear, the inner ear, and the brain. If tinnitus persists and its cause is unknown, a hearing test (audiogram)should be done. Measures can be taken to lessen the intensity oftinnitus. (12 Dec 1998) |

| ear, slanted | An ear that is slanted more than usual. Technically, an ear is slanted when the angle of the slope of the auricle is more than 15 degrees from the perpendicular. Also called a malrotated ear Considered a minor anomaly. The presence of 2 or more minor anomalies in a child increases the probability that the child has a major malformation. (12 Dec 1998) |
| ear tag | Common 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. (12 Dec 1998) |
| 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. (12 Dec 1998) |
| ear tube surgery | The removal of fluid (often infected) from the middle ear space by creating a incision in the eardrum. Ear tubes may be placed to maintain chronic drainage for several months. Indicated in cases of chronic or recurrent otitis media. (27 Sep 1997) |
| ear tumour | A disorder where there are noncancerous lumps or growths within the ear canal or on the pinna of the ear (external ear). most lumps are sebaceous cysts but some are bony overgrowths known as exostoses (or osteomas). If large enough they may interfere with hearing. In this case surgical removal may be required. (27 Sep 1997) |
| ear wax | The ear canal is shaped somewhat like an hourglass. The skin on the outer part of the canal has special glands that produce earwax. The purpose of this natural wax is to repel water and to trap dust and sand particles. Usually a small amount of wax accumulates, and then dries up and falls out of the ear canal caring 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. See: cerumen. (12 Dec 1998) |

| joints of ear bones | The joints of the ossicular chain consisting of incudomallear joint, incudostapedeal joint, and the tympanostapedeal syndesmosis. Synonym: articulationes ossiculorum auditus, joints of ear bones. (05 Mar 2000) |
| external ear | Which includes the auricle and the external acoustic, or auditory, meatus; the middle ear or the tympanic cavity with its ossicles; and the internal ear or inner ear, or labyrinth, which includes the saemicircular canals, vestibule, and cochlea. See: auricle. Synonym: auris. Origin: A.S. Eare (05 Mar 2000) |
| eye-ear plane | A standard craniometric reference plane passing through the right and left porion and the left orbitale; drawn on the profile radiograph or photograph from the superior margin of the acoustic meatus to the orbitale. Synonym: auriculo-infraorbital plane, eye-ear plane, Frankfort horizontal plane, Frankfort plane, infraorbitomeatal plane. (05 Mar 2000) |

| lop-ear | Congenital deformity of the external ear, with poor development of helix and anthelix. Synonym: bat ear. (05 Mar 2000) |
| low-set ear | An ear positionned below its normal location. Classified as a minor anomaly. Technically, the ear is low-set when the helix (of the ear) meets the cranium at a level below that of a horizontal plane through both inner canthi (the inside corners of the eyes). The presence of 2 or more minor anomalies in a child increases the probability that the child has a major malformation. (12 Dec 1998) |
