Hyaluronic acid filler injection is a minimally invasive procedure for facial rejuvenation that involves injecting filling materials to correct the volume or augment specific areas in the face. Deep nasolabial folds are a common concern in aging people. The simplest way to correct a deep nasolabial fold to rejuvenate the face is to inject Ristow's space with hyaluronic acid fillers. However, conventional injection methods, such as percutaneous injections using a needle, can cause severe complications, such as skin necrosis or blindness due to intravascular injections. Therefore, the aim of the present study was to introduce a safe technique for intraoral filler injections in deep nasolabial folds and review related anatomic features to evaluate the safety of this technique.
