My implant is still high, it hasn't dropped after a year and a half. What can I do?

I would like to express sorry for your loss. Implants have a tendency to ride high right after surgery especially when placed behind the muscle (subpectorally). In 3-6 months the implant drops as the skin stretches and the breast tissue expands resulting in softer, and more natural looking breasts. Please note that it is common for breasts to heal and adapt to implants at different rates.The driving factors that could allow the 'drop and fluff' include gravity, persistent inward and downward massaging, and use of pole wraps. However, all these factors are mostly helpful during the first months because the surrounding tissues are still adapting to the implants. In your case, the implant may not be dropping because the muscle attachments or the
inframammary fold attachments are really strong and they may be preventing the
implant from dropping completely. You may require an IMF release in the future
to symmetrize the breasts if it does not get better for time.Above all, the instructions of your surgeon take precedence over everything else you read on here. You can try continuing with massaging as directed by your surgeon to see if it works. If it doesn't, then share your concerns with your surgeon and they should be able to correct it.  

Hope this helps.

After 1.5 years, it is unlikely that your implant will continue to drop, despite massage. Your best course is to speak with your surgeon to determine what options are recommended for you. Sometimes a simple procedure to release the scar is all that is needed. If you have capsular contracture, a more extensive surgey may be in order. Best of luck to you!
