Do I need to ask for an Enbloc procedure only due to my old hard calcified silicone?

Trust in your surgeon to remove all aspects which need to be removed.  I recommend an in-office examination as well as a detailed discussion with a surgeon who you are comfortable with.   Finally, make sure your surgeon is a Double-Board Certified Plastic Surgeon certified by the American Board of Plastic Surgery (ABPS), a member of the American Society of Plastic Surgery (ASPS), a member of the American Society of Aesthetic Plastic Surgery (ASAPS), and a fellow of the American College of Surgeons (FACS).Best,Dr. DesaiBeverly Hills Institute for Aesthetic Plastic SurgeryHarvard Educated, Beverly Hills & Miami Beach TrainedDouble Board-Certified Beverly Hills Plastic Surgeon

Generally, an en block capsulectomy is best for old ruptured and calcified implants. In this procedure,this often commonly fold into not thinking that you need a left as the capsules actually holding up periareolar tissues.  I have seen this on many occasions which a capsulectomy is performed and then the surgeon is surprised to see that the patient actually did need a lift.  Another thing to consider in many of these cases is a re-positioning of implant into the subcutaneous pectoral location.   Make sure that you see a plastic surgeon who is very experienced in revisionary breast surgery. Best wishes to you.

Dear Trianna,it is hard to tell without an examination. I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.Daniel Barrett, MD, MHA, MS

An en bloc capsulectomy is typically performed in the presence of older ruptured silicone devices. Due to the viscous (think "honey") nature of the silicone fill, removing the entire capsule at once (without exposing the ruptured internal contents) is the most practical approach to ensuring complete removal.It is important to remember that while the "goal" is complete removal (capsule and contents) there is always the potential for some retained capsule or silicone. In most cases, the vast majority of the silicone/capsule will be removed and any residual is unlikely to cause an issue.As always, discuss your concerns with a board certified plastic surgeon (ABPS).

every attempt should be made to remove the entire capsule but no one can guarantee that it will be accomplished and you have to understand that deformities of your breast can occur if your skin is very thin as you mention.  Without photos, comments on a lift cannot be made.  Are you accepting of the outcome with removal alone???

Thank you for the question.  Based on your description, it   I would likely recommend en bloc removal of the breast implant. En bloc breast implant removal refers to a procedure where the breast implant and the surrounding capsule is removed as a single unit.  The procedure is performed such that the  contents within the breast implant capsule do not come into contact with the surrounding tissues. 
The procedure may be indicated when a patient has ruptured silicone gel breast implant (especially older silicone gel breast implants), or if the patient has concerns about "medical conditions" related to the breast implants.
 Best wishes.
