[Coverage of defects: principles].
The coverage of defects is a broad field with which the plastic surgeon is confronted daily within traumatic, tumoral or other context. The various techniques used are skin graft and flaps, forming both heterogeneous groups. Indeed, there are various types of skin graft although a common denominator is the need for a good recipient site in order to allows an adequate "take". On the other hand, flaps carry their own vascularization. Thus, they are not dependent of the recipient site for their survival. Those are divided into three groups: local flaps, pedicled flaps and free flaps. The choice of the adequate technique with respect to the defect to be covered depends on the characteristics of the defect, its localization, the functional requirements of the area, the exposed structures, the medical status of the patient. The possible morbidity left on the donor site the aesthetic and functional goals are taken into consideration. For each case, there are often several good options as well as others less optimal solutions. The existing solutions are often so numerous that the plastic surgeon is frequently able to solve all the types of defects.
