would moving my saline implants from under to over the muscle help me achieve a rounder, higher appearance? (photo)

Although you did not post a photo of your breasts exposed, what you show in a bra looks very nice. I suggest keeping the implants behind the muscle for better long-term results and less sagging. Most women cannot achieve the round ball look which is not a natural look. Placing the implants in front of the muscle will be firmer and much less support to the implants.

Dear barbbbieee,
I understand your concern. However, without a proper assessment, it would be difficult to determine what is wrong. Based on your question, it looks like the change of implant position will not place your implants higher. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Thanks for your question! I would need to see your current photos in order to determine if your wish pic is a reasonable result. Please post again with more photos. Thank you!
