The main focus in the surgical field is the modern treatment of skin tumors. Complete tumor removal (micrographically guided surgery/MKC or 3D histology) is of particular importance. The resulting tissue defects are closed using individually adapted plastic surgery techniques. The goal is optimal function and aesthetics. In particular, areas such as the nose, ear and lips, as well as defects near joints, often require complex treatment for reconstruction.
