Skin coverage includes all skin defects that cannot be healed in the normal way and require specific attention. These imperfections may be due to pathological causes (tumour removal, radiotherapy, and so on) or may have accidental causes.
The complexity of the technique will depend on whether or not tissue (cartilage, bone, tendon, nerves) and/or blood vessels are exposed. If these structures are not exposed, skin grafting will be used, but if they are, and if higher-quality tissue is required, pediculated or microsurgical flaps will be created.
