[Monitored cicatrization]

Directed healing is a therapeutic process that Raymond Vilain conceived as a sequence of: cleaning, granulation and formation of the epidermis. He suggested, to aid healing, the use of sofra-tulle and washing with isotonic solution or tap water, we have added the use of a hair dryer, in order to decrease the exudation from the wound. Such directed healing is particularly of interest for the integument and is difficult to apply to such structures as fat, fibrous tissues, bone and cartilage, or nerves and vessels. The "star" of directed healing is the granulation tissue. If healthy, it will support progressive marginal formation of the epidermis if the loss of tissue is not too great; if this loss is extensive, a graft will easily take on top of the layer of granules. If abnormal, the granules will lack tone. Healing will have to be renewed by appropriate treatment. We are all programmed to heal, except if we hinder the process by technical and psychological errors.
