In 5 cases, the graft was seen to have resorbed significantly necessitating further surgery using auricular cartilage
graft replacement for the original septal batten grafts; revision grafting was successful in all occasions.
 using a rabbit auricular cartilage
wound model, immunohistochemical staining of IGF-1 was used to define growth factor expression at the cartilage wound sites.
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.
Computed tomography (CT) of the left temporalbone demonstrated that the density of the auricular cartilage
was similar to that of bone (figure 1).
The author has developed a technique whereby the ENDURAGen alloplast acts as a carrier for autologous auricular cartilage
. When ENDURAGen is used as a carrier, the bulk of the reconstruction material comes from the autologous cartilage, not the alloplast.
Many flaps and grafts have been used to achieve this goal; among them are nasal septal (7) and auricular cartilage
, (8) epiglottic tissue, (9) thyroid cartilage, (10) costal cartilage, (11) sternocleidomastoid myoperiosteal flaps, (12) and hyoid bone.
Macroscopically, the lesion appears as a well-defined cystic cavity in the auricular cartilage
, which is often filled with clear to yellow fluid ("olive oil") that can be expressed (figure 1).
The purpose of this study was to evaluate whether ASCs could differentiate into auricular cartilage
and to know growth factors associated with regeneration of auricular cartilage
defects by ASCs in rabbits.
 reported that replacing the elastic auricular cartilage
fibers by collagen-like fibers increase at an advanced age.
starts to harden after the age of six.
The word ochronosis refers to the dark bluish black discoloration of connective tissues including the sclera, cornea, auricular cartilage
, heart valves, articular cartilage, tendons, and ligaments.
