Today I want to write about reverse double-eyelid surgery, the procedure to erase a pre-existing crease and create a monolid appearance.
Erase the crease? Technically, yes, you can simply excise the existing crease tissue.
But you will regret it.
Let me start with what the result looks like, before getting into the why.

The crease has effectively disappeared.
And the eye opening looks larger.
This is the look we are after.
What we actually do is drape the lid skin over the existing crease so it disappears from view. We do not excise the crease itself.
An earlier post covers this.

If this is the typical pre-op state with a visible double crease,

we drape the upper skin over the crease line so it is no longer visible from outside.
If a surgeon tries to erase the crease by cutting out the existing scarred skin, the complications are severe.
There will not be enough skin to work with, and the resulting scar is very hard to manage.

The scar issue alone can be devastating.
And the eye will not close fully because of the skin shortage.

This material is drawn from a paper I recently submitted, fresh off the press.
So-called "crease removal surgery" is performed in this manner. It is not actually about untying or cutting out the existing crease.
Surgeries that excise the crease tissue itself should never be done. The whole point is to roll the crease internally so it is no longer visible.
Surgery takes about an hour, and most of the swelling resolves within one to two weeks.

The skin gets folded inward like this.
