INJECTABLE HYALURONIC ACID-CONTAINING DUAL-PHASE COMPOSITIONS, PARTICULARLY USEFUL IN CORRECTIVE AND PLASTIC SURGERY

摘要

Dual-phase compositions containing a polymer selected from hyaluronic acid and its salts, method for preparing the compositions, and filler material useful in corrective and plastic surgery based on said dual-phase compositions. The compositions comprise an injectable suspension with a dispersed phase composed of insoluble fragments of a hydrogel of said strongly cross-linked polymer and a continuous phase composed of an aqueous solution of said polymer and/or another biocompatible polymer, selected from proteins, polysaccharides and derivatives thereof, non cross-linked or weakly cross-linked.
