Hello, Thank you for your questions about tummy tuck scar placement. In general, most tummy tuck scars can be concealed under "reasonable" underwear. However, this needs to be carefully discussed with your plastic surgeon before (not after) your tummy tuck. Lowering your tummy tuck scar after your tummy tuck can be very difficult. Tummy tuck scar placement can also be limited by your unique anatomy or prior scars, like C-section or gall blabber scars. Some plastic surgeons balance hiding the tummy tuck scar and achieving a great body shape. Sometimes, if the tummy tuck scar is placed very low, the tummy tuck can appear very square or "box-like". If however, the tummy tuck scar is placed high around the hips (think high lateral tension tummy tuck), the overall tummy shape may be more appealing, but the tummy tuck scar is more visible. Again, this is important to discuss these concerns with your plastic surgeon before your tummy tuck. Yes, you can wear a bikini one year after a tummy tuck. I hope that I have answered your questions regarding tummy tuck scar placement. If you have any more questions regarding the tummy tuck or abdominoplasty, please contact my office. Sincerely, Dr. Katzen.
