[Free fat flap for the treatment of Parry-Romberg disease in children]. / Trasplante libre de grasa para tratamiento de la enfermedad de Parry-Romberg infantil.

Progressive hemifacial Atrophy (PHA) or Romberg's Disease is a rare entity of unknown etiology, which most often affects only one side of the face and can include all tissue planes in different grades of severity. Of the several treatments proposed, pedicled or free flaps seem to achieve the best cosmetic results in severe cases. In mild to moderate cases, free autologous fat transplant may obtain optimal results with lower complexity, cost and morbidity. The presence of multiple adipoblasts might increase the possibilities of graft take, particularly in children. Furthermore, refinements in the processes of extraction, preparation and reintroduction of the fat have contributed to improve the results that may be long lasting. We present 2 cases of PHA in 2 girls (11 and 13 years old), that were treated by lipofilling. No complications occurred. In both cases we observed a small reduction in the volume of the initial graft. Thus the procedure was repeated 6 months later to improve facial symmetry. Results have been excellent in one year follow-up.

La hemiatrofia facial progresiva (HAFP) o enfermedad de Romberg es una rara entidad de etiología desconocida, que mayoritariamente afecta a un solo lado de la cara, pudiendo incluir todos los planos tisulares en diferentes grados de severidad. De los diferentes tratamientos propuestos, en los casos severos, los colgajos pediculados o libres parecen lograr los mejores resultados estéticos. Para los casos leves o moderados, el trasplante libre de grasa autóloga puede obtener resultados óptimos con menor complejidad, coste y morbilidad. La presencia de múltiples adipoblastos en los niños puede aumentar las posibilidades de prendimiento del injerto. Además los refinamientos en los procesos de extracción, procesado y reintroducción de la grasa han contribuido a perfeccionar los resultados y a que éstos sean más duraderos. Presentamos dos casos de HAFP en 2 niñas de 11 y 13 años que fueron tratados mediante lipoinfiltración. No se observaron complicaciones. En ambos casos se observó una discreta reducción del volumen inicial, por lo que se repitió el procedimiento a los 6 meses para mejorar la simetría facial. Los resultados han sido excelentes tras un año de seguimiento (AU)
