Nonsurgical rhinoplasty procedures are not without risks: although rare, intravascular injections of hyaluronic acid can lead to serious complications. Very few authors have reported using cannulas for filler injection in the nose. The purpose of this article is to describe how the authors perform nonsurgical rhinoplasty using a single entry point and cannulas, significantly reducing vascular and infection risks. The procedure described in this article can be applied to all indications of nonsurgical rhinoplasty. The key point of the authors' procedure is the definition of a single, medial entry point. Using a 5-cm, 25-gauge, dome-shaped cannula, all nasal regions can be reached, from the anterior nasal spine to the nasion. The authors' nonsurgical rhinoplasty procedure using cannulas reduces complications and provides results similar to those achieved with needles.
