Can a Damaged or Removed Forehead Muscle Tissue Ever Be Repaired from Coronal Brow Lift? (photo)

As mentioned, its difficult for us to give you appropriate advice without a photo. But there is a significant amount of information that would help us:  what technique browlift was used? Hairline? Coronal? Endoscopic? When you say "missing tissue" about the brow, are you talking about in the forehead, or between the eyebrows? Frontalis muscle is not removed during a browlift, but corrugators often are [the muscle between the eyebrows that give you an angry look].

For contour irregularities, I often use fat grafting, which is a more permanent solution than fillers.

Again, post photos for a more personalized advice.

is certainly not stories we like to hear.  However in order to truly understand your dilemma, a photo and knowledge of just what kind of surgery was done is needed.  You should get your operative report from your surgeon and seek a second opinion.
