Basic Techniques in Autogenous Microtia Repair

Abstract

Although several techniques can be used for microtia repair, some standard procedures have been developed over the past few decades. In specialized centers, these techniques are performed most frequently. They include two to four operative steps using autogenous rib cartilage for the framework and local skin for its tegument. We have been using this technique presented here in more than 800 cases over the past two decades with good and mostly stable results.

Recent Applications of Polymeric Biomaterials and Stem Cells in Tissue Engineering and Regenerative Medicine

“…133 The use of costal cartilage is a complex procedure, however, and it is difficult to configure the shape that matches the contralateral auricle. 131,132,134 As such, complications, including inadequate shape, progressive dimensional change, and donor site morbidity, continue to be problematic. 133,134 Alternative approaches using alloplastic implants, such as silicon or high-density polyethylene (HDPE), have been introduced and approved by the Food and Drug Administration (FDA) for clinical applications.…”

Auricular Reconstruction: Surgical Innovations, Training Methods, and an Attempt for a Look Forward

“…21 The perfection of the auricular reconstruction, the continuous development of existing techniques, and the best possible combination of aesthetic and functional rehabilitation, are the clinical and scientific focus of our work. [22][23][24][25][26][27] Together we have reconstructed more than 1,500 auricles over the last 25 years.…”
