Lip reconstruction after mucocele removal - What should I expect from my results? (photos)

I had a mucocele removal and sadly some lip tissue did not grow back leaving a noticable gap and making it difficult to close my lips together normally. I want the best technique possible for my case. I have heard of lip injectibles but it can cause migration/is temporary and fat grafting I heard can look bad. It has already been 4-5 months since the mucocele excision. Flap surgery is my main option I believe? How can similar can I expect the lip reconstruction to make my lips the same as before
