Anatomical Reproducibility through 3D Printing in Cranio-Maxillo-Facial Defects

La planificacion y reconstruccion 3D en defectos craneofaciales se basa en principios anatomicos de simetria y pasividad en la adaptacion, evolucionando rapidamente en los ultimos anos. El presente articulo presenta la posibilidad de rehabilitacion de un paciente con trauma importante gracias a un implante craneofacial extenso. Se presenta el caso de un sujeto con evolucion de 10 anos de una secuela de trauma, donde perdio el hueso frontal, pared supraorbitaria y parte de la fosa temporal. A partir de una tomografia computadorizada, utilizando un software de planificacion Materialise (3-Matic and Mimics) se construyo un modelo virtual a traves de un implante de pieza unica para cubrir integramente el defecto; se planifico la posicion junto a la cantidad y longitud de tornillos a utilizar. A continuacion se realizo la impresion de la pieza mediante una impresora laser de titanio donde la pieza fue construida segun las especificaciones de la planificacion; la cirugia fue realizada sin complicaciones en el cual el implante fue instalado a traves de un acceso coronal sin necesidad de ningun tipo de adaptacion. Despues de dos anos de seguimiento se observa una posicion correcta, simetrica y en ausencia de infecciones u otro tipo de alteracion. Se concluye que la planificacion e impresion 3D es viable de realizar en reconstruccion craneofacial con baja morbilidad, disminucion del tiempo quirurgico, obteniendo una adecuada simetria y estetica facial.
