[Auricular malformations]
Abstract:
Reconstruction of complex auricular malformations is one of the longest surgical technique to master, because it requires an extremely detailed analysis of the anomaly and of the skin potential, as well as a to learn how to carve a complex 3D structure in costal cartilage. Small anomalies can be taken care of by any plastic surgeon, providing that he/she is aware of all the refinements of ear surgery. In this chapter, we analyze retrospectively 30 years of auricular reconstruction, ranging from small anomalies to microtia (2500 cases), excluding aesthetics variants such as prominent ears.

The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of...
