Engineered Cartilage Covered Ear Implants for Auricular Cartilage Reconstruction
Biomacromolecules, 2010Cartilage tissues are often required for auricular tissue reconstruction. Currently, alloplastic ear-shaped medical implants composed of silicon and polyethylene are being used clinically. However, the use of these implants is often associated with complications, including inflammation, infection, erosion, and dislodgement.

Scaffolds are widely used to reconstruct cartilage. Yet, the fabrication of a scaffold with a highly organized microenvironment that closely resembles native cartilage remains a major challenge. Scaffolds derived from acellular extracellular matrices are able to provide such a microenvironment.

Tissue-Engineered Flexible Ear-Shaped Cartilage
Plastic and Reconstructive Surgery, 2005Previous attempts to engineer human ear-shaped constructs mimicked human shape but lacked the flexibility and size of a human ear. Recently, the authors engineered flexible cartilage by incorporating a perichondrium-like layer into the construct. In this study, they used lyophilized swine perichondrium as a pseudoperichondrium, examined its ability to ...

Simplified harvesting of the ear cartilage graft
Aesthetic Plastic Surgery, 1986A simplified technique of harvesting of the ear cartilage graft is described which (1) uses a postauricular incision to minimize the visible scars, (2) removes the whole floor of the conchal fossa to avoid the irregularities, and (3) uses a tie-over dressing to eliminate the need for a head dressing. This technique has been used on 88 patients with one

Ultrastructure of elastic cartilage in the rat external ear
Cell and Tissue Research, 1981The structure of elastic cartilage in the external ear of the rat was investigated by transmission and scanning electron microscopy. The narrow subperichondrial, boundary zone contains predominantly ovoid cells rich in cell organelles: mitochondria, Golgi complex, granular endoplasmic reticulum and small (40--100 nm) vesicles.

Otoplasty: Anterior Abrasion of Ear Cartilage with Dermabrader
Aesthetic Plastic Surgery, 2003The international literature describes many different techniques for correcting prominent ears. Some of these techniques use weakening of the anterior surface in an "open or close" way. Others use suturing of the unfold antihelix. Still others suture the concha with mastoid, and some combine several of these procedures.

The Effects of Resorbable Plates on Rabbit Ear Cartilage
Archives of Facial Plastic Surgery, 1999Background When performing septorhinoplasty, deviated segments of septal cartilage can be straightened using cartilage or bone as splinting grafts. In some cases, autologous material is not available without an additional surgical procedure to harvest cartilage or bone.

1987
The use of ear cartilage for auriculoplasty was no novelty by the start of the 1970s. It had been used successfully in different ways for partial ear repair (Adams, Navabi, Cardoso and Sperli, Antia, Millard, Lewin and Argamoso, and others), but the opinion prevailed that there was not enough cartilage for subtotal reconstruction.

Grafting the Nasal Dorsum with Tandem Ear Cartilage
Plastic and Reconstructive Surgery, 2003A technique for autogenous grafting of the nasal dorsum with ear cartilage is suggested based on the results of 25 consecutive cases. The technique involves (1) harvesting the entire cymba conchae and cavum conchae of the ear; (2) separating them and suturing them to each other in tandem fashion; (3) filling the underside concavity of the cymba conchae

Studies on glycosaminoglycans of regenerating rabbit ear cartilage
Developmental Biology, 1981Abstract Cartilage regeneration in the adult rabbit ear was examined with respect to glycosaminoglycan (GAG) synthesis at various stages of the regeneration process. Increased hyaluronic acid and chondroitin sulfate synthesis was first seen 31 days after wounding, when a metachromatic cartilage matrix could be distinguished from blastemal cells ...
