Cannulas for facial filler placement.

With more physicians performing injections to the face in increasingly sophisticated ways, techniques must evolve accordingly. Injectables are no longer mere wrinkle fillers but true panfacial volumizers that are placed in many different planes and tissues of the face, in contrast to fillers of the past used for the dermis. This development is providing better results previously not achievable with off-the-shelf fillers. Microcannulas represent a step forward in enhancing surgeons' ability to fill the face with less discomfort, edema, and ecchymosis, with faster recovery. Microcannulas will probably play a role in volume replacement for many years to come.
