Can Hydroxyapatite Be Used For Orbital And Midface Augmentation?
Q: Dr. Eppley, Hello. I have heard about you through some of my friends. My concern is about orbital rim, premaxillary and infraorbital areas. My wish is augmentation on the infraorbital area, and orbital rim contouring around the eye to correct the hollowness, so orbital rim and premaxillary zone augmentation. I want all of these done with HA- hydroxyapatite.
My question is can HA be used on the infraorbital area, orbital rimm and premaxillary areas. I need to have an idea if HA can used on such area of faceYou can see an image on attachment , drawn the area with red color which I want augmentation using HA.
A:When it comes to the use of hydroxyapatite cement that material is going to work better for bony concavities than bony convexities. Thus the paranasal region is a good place for it. The lower orbital is OK but not great and you simply can’t build the material out into space. (upper orbital rim) HA is intraoperatively mixed to create a paste which is then applied and molded into the desired shape and then allowed to set. So the base upon which it is applied is a major determinant of its predictable augmentative effect.
