Hollow temples after facelift - will this correct itself over time or should I consider a procedure to restore balance? (photos)

The temporal hollowing is probably more pronounced after your surgery and was less noticeable to you before surgery. This will not improve with time. You can have some filler added to this area ( HA fillers, biostimulatory fillers, or fat). These will improve the contour and diminish the hollowing. For a permanent improvement, I recommend and prefer silicone temporal implants. They provide an improved contour from the temporal crest down to the lateral orbit. They are placed through a small incision in the hairline.

It is unlikely that face lift is the cause of temple hollowing. Very likely it was present before FL but you and your surgeon did not pay much attention to that?. This condition will not improve in time and needs to be addressed. Options are fat grafts (ultra sound guided), fillers, ) or implants. This is something that you should discuss with your surgeon or seek a second opinion consultation. Good luck.
