Because of its simplicity, augmentation rhinoplasty with filler material has been used as alternative choice of the operative augmentation rhinoplasty. With development of various filler materials the duration of which is long, the augmentation rhinoplasty using filler material has wide usage. This article describes the choice of filler suitable for augmentation rhinoplasty. As skin and soft tissue are abundant at the nasal tip and root, they are easily elevated when filler material is injected. However, in case of nasal dorsum, especially supratip depression, there is a lack of skin and soft tissue, therefore, the filler material injected is redistributed into the nasal tip and dorsum. Ideal filler material for augmentation rhinoplasty should be located at the injection site without quantitative change. Fortunately, 3.3% PAAG(polyacrylamide gel) has hard consistency, but no component change, and has long duration. Therefore, it seems to be an ideal filler material among numerous filler materials currently sold.
