Head and neck skin expansion: assessment of efficiency for the treatment of lesions in the lower half of the face.

The treatment of sequelae for burns or other loss of perioral tissues is complex due to the site where they occur, its functional importance, and social and esthetic aspects. Functional consequences of burns to this area are cutaneous retraction and a lack of skin that can lead to an inability to close the oral aperture, compromising the provision of dental hygiene and intubation procedures. The aim of the present publication was to evaluate the efficacy of chin, labial and jugal cutaneous expansions for the treatment of perioral lesions and lesions of the lower half of the face in our retrospective series of patients. We collected data and photography from digital files for each patient. Proportion of scarred skin that could be treated by one or several expansion procedures was evaluated. The main outcome was the resection of 50% or more initial lesions. Side effects were assessed. Out of a total of 33 expanders, 28 were at the jugal level, 5 were chin expanders, and none were labial expanders. This equated to the inclusion of fourteen patients. The average percentage of the lesion that was removed after the perioral expansion protocol was 68.9% (40%-100%). 85% of patients had a positive outcome. 12% of procedures were complicated by hematoma, infection or prosthesis exposure. Each time that the lesional area could be fully (i.e. 100%) treated, only a single expansion was used. Head and neck expansion is the technique of choice for reconstruction of the lower half of the face and the horizontal part of the neck in terms of efficiency and safety.
