Hi I'm Dr Kim of Teuim. I do perform temroral(temple) augmentation with fat graft. It is very common procedure. Fat injected over temporal area provides volumetric fulfillment like other areas as well. Fat absorption rate is just a bit higher that that of forehead, but if the patient is young, then it will be less than that of old people. Slight amount of re-touch is usually needed in a few month in some patients, but I cannot guarantee because there is no such a rule. Also, patients should understand that the hollowness of temple is sometimes due to protrusion of zygoma relatively. In this case zygoma reduction is helpful. Only for fat graft, 3-4 days of staying will be enough, but if affordable, I recommend you to visit again in 6 month time for minor re-touch. Anyway, thank you for informing that we haven't listed temple augmentation on our web. Thank you.
