The use of large-particle stabilized hyaluronic acid-based gel of nonanimal origin (NASHA(TM)) for facial aesthetic procedures is widespread and increasing. A panel of experts with extensive clinical experience with NASHA-based gel recently attended an advisory board meeting to develop guidelines for its use in volumetric tissue augmentation. Discussions included details of the blunt-cannula injection technique currently recommended for administration of large-particle NASHA-based gel. With the aim of optimizing patient comfort and control over administration of NASHA-based gel, the panel members explored an alternative, sharp-needle technique. In this article we describe the new technique in detail, together with practical recommendations and precautions. The technique has several advantages over blunt-cannula injection: improved patient comfort, lack of need for a skin incision, increased precision regarding the implant position, and improved control of injection volume. However, the sharp-needle technique requires a high level of skill and a good knowledge of facial anatomy.
