ABSTRACT:
An improved micro-implantation method and composition for filling depressed scars, unsymmetrical orbital floors, muscle, lip, and other soft tissue defects is provided for use in reconstructive surgery procedures. Textured micro particles having an outside diameter between about 30 microns and 3000 microns are used with an appropriate physiologic vehicle cannula and syringe and/or pressure delivery system into a predetermined locus. The particles provide long-term filling of defects without migration loss.
