Figure 5. Hyaluronic acid injection to the superior sulcus. The needle or cannula should enter along the superior orbital rim at a 30° angle. After the needle has reached the bone, it should be slightly withdrawn to the preperiosteal space to inject into the suborbicularis plane. Adapted with permission from Looi et al.[31]
