Labia Minora Restoration Surgery

Has anyone ever had a labia minora restoration surgery? I've had three vaginal births and a miscarriage. I have a rip that never healed and causes a lot of discomfort. On the 22nd I'll be having surgery to correct it. I've had surgeries before so I'm not worried about going under...just about the fact that it's such a sensitive are and so close to my clitoris. I'm just wondering if anyone else has gone through this and what it was like. What should I expect?
