Valoramos la eficacia de un apósito autoadhesivo para prevenir las cicatrices hipertróficas sobre un grupo de pacientes sometidas a cirugía de reducción mamaria. Tras la curación de las heridas, aplicamos en todas las pacientes un protocolo preventivo mediante compresión y apósito adhesivo.

Keloids are locally aggressive scars that typically invade into healthy surrounding skin and cause both physical and psychosocial distress to the patient. These pathological scars occur following minimal skin trauma after a variety of causes including burns and trauma. Although the pathogenesis of keloid disease is not well understood, it is considered to be the end product of an abnormal healing process. The aim of this review was to investigate the molecular and cellular pathobiology of keloid disease in relation to the normal wound healing process. This review presents a detailed account of individual phases of the healing process and how they may potentially be implicated in aberrant raised scar formation, which may help in clarifying the mechanisms involved in keloid disease pathogenesis.
The physiopathogenesis of proliferative scarring in human skin is not well understood. Furthermore, knowledge of the precise mechanisms of action for physical treatment modalities is limited. Compression garments, occlusive/adhesive skin taping, and silicone gel sheets are applied to form an occlusion on the scar surface, reduce tension, and/or increase pressure on the scar itself. The mechanisms by which the external or superficial actions of these treatments cause remission of a protruding scar may be related to mechanoreceptor (nociceptor and cellular mechanoreceptor) responses.
