au·ric·u·lar car·ti·lage

(awr-ik'yū-lăr kahr'ti-lăj) [TA]
Cartilage of the auricle (pinna) of external ear.


a specialized, gristly connective tissue present in both mature animals and embryos, providing a model in which most of the bones develop, and constituting an important part of the organism's growth mechanism; the three most important types are hyaline cartilage, elastic cartilage and fibrocartilage. Also, a general term for a mass of such tissue in a particular site in the body.

alar c's
the cartilages of the wings of the nose.
annular ear cartilage
a ring of cartilage interposed between the rolled-up auricular cartilage and the skull.
arthrodial cartilage, articular cartilage
that clothing the articular surfaces of synovial joints.
arytenoid c's
two pyramid-shaped cartilages of the larynx.
auricular cartilage
cartilage of the pinna and much of the external ear canal.
cartilage canals
tunnels containing blood vessels incorporated in developing cartilage.
connecting cartilage
that connecting the surfaces of an immovable joint.
costal cartilage
a bar of hyaline cartilage that attaches a rib to the sternum in the case of true ribs, or to the immediately cranial rib in the case of the anterior false ribs.
cricoid cartilage
a ringlike cartilage forming the caudal part of the larynx.
diarthrodial cartilage
articular cartilage.
distal phalangeal cartilage
the ungual cartilages of the third phalanx in the horse lie mostly against the hoof wall but can be palpated if ossified. See also sidebone.
elastic cartilage
cartilage that is more opaque, flexible and elastic than hyaline cartilage, and is further distinguished by its yellow color. The ground substance is penetrated in all directions by frequently branching fibers that give all of the reactions for elastin.
cartilage emboli
see fibrocartilaginous embolic myelopathy.
ensiform cartilage
xiphoid process.
fibrous cartilage
floating cartilage
a detached portion of semilunar cartilage in the stifle joint.
hoof cartilage
see distal phalangeal cartilage (above).
hyaline cartilage
flexible, somewhat elastic, semitransparent cartilage with an opalescent bluish tint, composed of a basophilic fibril-containing substance with cavities in which the chondrocytes occur.
interarytenoid cartilage
an occasional cartilage located between the two arytenoid cartilages.
nasal cartilage
rostral end to the internasal septum, separating the nasal cavities and anchoring the other cartilages around the nostrils.
parapatellar cartilage
cartilaginous plates medial and lateral to the patella in some species, e.g. dogs.
permanent cartilage
cartilage that does not normally become ossified.
retained enchondral cartilage cores
occur in ulnar metaphysis and lateral femoral condyles of young, giant breed dogs. Visible radiographically as radiolucent inverted cones, extending into the metaphysis, they are often associated with growth deformities such as forelimb valgus and genu valgum.
reticular cartilage
elastic cartilage.
scapular cartilage
dorsal extension of the scapula in ungulates; tends to calcify with age.
cartilage scissors
used for ear cropping in dogs.
semilunar cartilage
one of the two intra-articular cartilages of the stifle joint.
temporary cartilage
cartilage that is normally destined to be replaced by bone.
thyroid cartilage
the unpaired cartilage of the larynx to which the vocal folds attach.
tibial cartilage
the bed of cartilage located on the caudal surface of the intertarsal joint of birds; the tendons of the digital flexors pass through it.
ungual cartilage
see distal phalangeal cartilage (above).
vomeronasal cartilage
either of the two narrow strips of cartilage, one on each side, of the nasal septum supporting the vomeronasal organ.
xiphoid cartilage
posterior continuation of the sternum; supports the anterior abdominal wall, especially the linea alba.
yellow cartilage
elastic cartilage.

Common uses for auricular cartilage grafts include alar batten grafts to treat nasal sidewall collapse; dorsal onlay grafts to treat the over-resected nasal dorsum or the low radix or, when shaved thin, to camouflage dorsal irregularities in rhinoplasty surgery; nasal tip grafts in primary and secondary rhinoplasty; postauricular perichondrium grafts to overlay the nasal tip and dorsum in the thin-skinned rhinoplasty patient; nasal alar reconstruction after skin cancer resection; lower lid space grafts to treat ectropian in the paralytic lower lid; and cartilage graft material to assist in repairing septal perforations.
The auricular cartilage is an elastic substance that provides flexibility to the auricle.

The difference between ossification and calcification of the auricular cartilage cannot be ascertained clinically; the distinction can be made only by histologic evaluation.
Many surgeons appreciate the utility of auricular cartilage as an autologous graft material for nasal augmentation, but the natural concavities and convexities of harvested conchal bowl cartilage can make achieving a straight and even dorsum technically challenging.
