My brow bone is not very prominent, so I'm confident that a shave will be sufficient instead of a full forehead reconstruction.  In fact I could probably make it through life without any forehead work at all (I pass pretty close to 100% already), but my brow bossing is just something that bothers me personally when I look in the mirror everyday.

I'm happy with my hairline (almost no hair loss), and I'm happy with my eyes (they are somewhat hooded, but I like my Asian-looking eyes).  So I don't think I need a scalp advance or an upper blepharoplasty... except... will they be necessary if I get my brow bone ground down?  Will I have extra loose skin as a result of some bone being shaved away?  My concern is that I will have sagging eyes due to loose skin or something, if I don't do an upper blehpharoplasty and/or scalp advance.

I'd appreciate any advice on this.  Thanks!

Depending on where they do the incision, there will be no loose skin. Even when not doing a scalp advance, they'll have to remove some excess skin at the incision site so as to make up for the loss of volume of bone that is no longer there.

This is why my doctor advised against a 'behind the hairline' incision because when you do that, the hairline will definitely get raised because the skin will have to get tightened and if it's tightened behind the hairline then the hairline goes up.

Whereas when you have a hairline incision, you can remove the excess skin in the non hair area and keep the hairline where it is (or advance it if needed).

They always tighten up the extra skin (if you have some forehead wrinkless, that will be gone too...). With simple shaving technique, there isnt much extra skin because there isnt significant difference in bone.. With forehead type3 reconstruction, there is more change, and more extra skin that gets removed.

Upper blepharoplasty can have great rejuvenation effect. FFs surgeons often do slight upper blepharoplasty to avoid too much eyebrow lift, which is to achieve more natural result (too much eyebrow lift achieves the opposite).
