This, like you explained it with () and o under, is the usual result of penile-inversion based techniques. If you look at SRS results online, this is the common shape, as penile flap is inverted, it means that labia minora starts above vaginal entrance, instead of being all around vaginal entrance. I dont want to ask any inappropriate question, but how come you were not aware of this before surgery? I mean, you were shown photos of your surgeons previous results?
How much can be this improved with revision depends on your anatomy. Experienced SRS surgeons have experience with this, as many patients come back dissatisfied with exactly the same thing as you are. But there simply arent many post-revision photos out there, even less before-after results. Maybe the best chance to see what can be done, is consult with surgeons, and ask to see pictures.
One way this can be improved, is to use some of labia majora skin, and make it into a fold, starting from lower end of vaginal entrance up until above vaginal entrance, where they can join it with labia minora. I cant promise you anything. Best that you can do now is wait until you are healed enough, that your surgeon can give a fair evaluation on what can be done and corrected. Until you are fully healed he can only speculate on what he will and will not be able to do.
