I agree that an in person evaluation to evaluate the scar, the mobility and quality of your tissues is essential before recommending surgery, laser, or both. If your plastic surgeon is uncomfortable with any additional intervention it is reasonable to seek a consultation for a second opinion.
The only way to provide you with accurate information and proper treatment recommendations is with a physical examination in person by an experienced board certified plastic surgeon. Scars can be lowered, lightened, or revised. The pubic triangle can also be revised not only surgically but with laser hair removal. Your options might be a combination of surgical and non-surgical treatments. Best of luck to you.
