Looks like nobody's replied yet, so I can only speak from my own experience. I'm 22 now, and as a baby, I was diagnosed with a hemangioma that covered my lower lip, chin, right side of my face, and right ear. It was massive—my face was basically three times its normal size in those spots and dark red. The redness faded over the years, but the swelling stayed. Back in the early '90s, my parents took me all over the US looking for help, but everyone turned us down because it was too risky; the hemangioma went deep into the tissue, and there was a real chance of destroying the muscle. We even tried specialists in Vienna and Italy, but got the same answers. Finally, we ran into Dr. Zlatko Matulić, who was willing to operate, though he warned my parents it could go south—meaning I could lose the ability to speak if the surgery hit the jaw or lip muscles. They took the gamble, and after a four-hour surgery, the results were actually great. After that first one (I think I was 7 or 8), I had two more corrective plastic surgeries to reduce the swelling and scarring (once at 11, once at 13). Once I hit adulthood, the doctor suggested a few more, so I had two more procedures to try and smooth out the scars.
I’m incredibly happy with how things turned out. I'm beyond grateful to Dr. Zlatko Matulić for stepping up and saving me. The scars are still visible, and I know I’ll never have a "normal" lip, but honestly, it doesn't matter knowing how bad it could have been.
So, I’d definitely advise going for the surgery if there isn't a huge risk (your doctors will know best) and if the hemangioma bothers you. 👍 Unfortunately, I can't point you toward a specific place to get it done, since I had all five of my surgeries in San Diego with that same doctor.
