Objectives: There is significant variation in treatment parameters when treating the infraorbital region. Altough in this presentation i will share my own experience & method i am using to avoid immediate & long term complications. The choice of the optimal filling material, and proper understanding of the anatomy of this delicated region & a proper technique will contribute to a safe, effective, and natural result. i have used a Hyaluronic Acid filler with low g prime low bdde , and low risk for the possible post injection edema. I use always a 25 or 23 g cannula (never thinner to avoid any vascular risk Introduction: 6 also to avoid bruising), I inject with retrograde linear threading technique very slowly a small quantity never more than 0,4 ml per side. i inject the filler pre-periosteally, deep to orbicularis oculi muscle, anterior to the inferior orbital rim to avoid the tyndall effect. Topical anesthetic is not commonly used. Side effects were generally mild and included very rarely bruising (because of the use of the cannula) , edema, and contour irregularities, imperfect correction. Non surgical correction of the tear trough deformity with soft tissue filler is a minimally invasive procedure with Materials / method: ong-lasting effects. It is essential to have a fundamental understanding of the relevant anatomy and ideal injection technique to provide excellent patient outcomes and prevent serious complications. However i had in my experience some cases of a chronic eyelids edema even 1 year after the procedure probably because of the lymphatic circulation compression in this area. I am considering to use always more autologous gel platelet rich growth factors to treat the tear trough deformity to avoid any type of complications in future.
