Will nipples sensation come back and breasts go back to normal after explant?

Hello,
Thank you for your enquiry. The photographic information is very helpful.
About 15% of women have permanent loss of sensation following breast implant surgery. In most cases, the sensation returns over the first year following surgery. I am not aware of any studies looking into sensation returning or getting worse of explantation. I don't think there would be a dramatic change because with implant removal, less cutting into normal tissue is involved.
For implant removal, the existing scar is often extended slightly, especially if there is a capsulectomy.
You will have more droopiness than before surgery. However, in your age, the skin normally retracts a lot following implant removal.
I would suggest to confirm this with your surgeon.

Thank you for your photos and questions. When your implants are removed the surgeon can use the same scar as when they were inserted. It in most cases will be the same size or smaller. The numbness may improve or stay the same. It is not likely to worsen. If you are not having issues with the capsules and your implants are not ruptured you can elect to leave the capsules behind. You will lose the fullness that the implants provided when they are removed, but your skin will retract to some degree. You may have some looseness but it should be an acceptable result.

Good evening,
If you are not experiencing any CC symptoms or BII concerns then you do not have to remove the capsules, and it likely can be done through the same incision. Your sensation may return some or all or not at all- it's totally unpredictable and only time will tell. I place a drain for five days, and then have my patients wear a nice tight compression bra for 12 weeks- by doing it this way 95% of my patients go right back to the look they had pre-augmentation and do not require any further surgery or lifting.
