This is not a silly question. In fact, it is a common one and an important one to ask your surgeon. As with any surgery, there are risks of complications like decreased sensation, but in the right hands and with excellent knowledge of the anatomy, the risk is quite low. The excess skin of the labia near the clitoral hood is common. Make sure the surgeon you go with has vast experience with happy patients after labiaplasty.
Tummy tuck is a wonderful surgery after having children and even better after C-section. Having prior C-sections does not negatively effect your tummy tuck. In fact, usually the tummy tuck scar is placed below the old C-section scars and is removed with the excess skin of the tummy. Of course, you should see a Board Certified Plastic Surgeon who specializes in body contouring to have an in depth consultation to discuss your options.
Thank you for your inquiry. Without seeing you in person or reviewing your photos and doing an online or virtual consult, it would be hard to tell you definitively whether the breast lift would help that area. Typically, the breast lift improves the excess skin and sagging above the breast crease (inframammary fold). At times, liposuction is done to the fat roll under the IMF to reduce the appearance of fat on top of the ribs.
It is recommended to avoid treatment with the deeper transducers over the nasolabial fold because of a small risk of causing temporary injury to a nerve located in this area. However, by treating the surrounding tissues, you are still able to safely achieve a lifting of this tissue. Ulthera is an excellent treatment for stimulating collagen and achieving lift in the face for patients with early skin laxity.
