Can an upper eyelid surgical approach (to avoid visible scars on forhead) be used to decrease a horizontal forehead deep crease?

With difficulty: It is possible but difficult to do this through the upper lids. A more effective approach is endoscopically through small incisions hidden behind the hairline. Unless you are bald, that is the way to go.

Forehead wrinkles: The deep lines across your forehead can be addressed in a standard brow lift but not in the transblepahroplasty brow lift.
