[Medicolegal aspects of esthetic surgery].

The particular features of the contractual agreement binding patient and plastic surgeon are recalled. The obligation of the result appears to be distorted in the course of jurisprudence. The severity of the judgements means that great care must be taken in the management before, during and after the operation (study of the patient's motivations, informed consent, iconographic survey, technical equipment, postoperative care,...). The problem of competence and the technical training of the surgeon are also discussed.
