How likely will my breasts return to normal after explant surgery? Total Capsulectomy or Capsulotomy? Possible complications?

Your breasts will not look the same as before augmentation, but due to the smaller implant size and your age you will probably regain much of your prior look. You will lose the fullness and volume that the implants provide. Since an examination reveals better information I encourage you to discuss your questions with your surgeon.

Thank you for the question.   Nothing will replace in-person evaluation when it comes to providing you with good advice. If I were seeing you in consultation, I would want to get a good idea of what breast size/shape you would be pleased with. This may be best communicated with the help of goal photographs and/or  computer imaging.  Then, once we have established what your goals are, I would be able to help you determine whether breast implant removal surgery alone versus downsizing of breast implants (plus any maneuvers necessary) would be necessary to achieve an outcome that  you would be pleased with.
 
Generally speaking, what your breasts will look like after explantation depends on several factors such as: the quality of skin elasticity (the better the elasticity the better the skin will bounce back), the size of the implants used (the larger the implant the more trouble you may have with redundant skin), and the amount of breast tissue present at this time (which may have changed since the time of your breast augmentation).
Life experience since your breast augmentation procedure, such as pregnancy or weight gain weight loss, will potentially influence the factors discussed above. If you take these factors into consideration and apply them to your specific circumstances you may get a good idea of what to expect after the implants are removed.
 Patience is definitely indicated after removal of breast implants; it will take many months/year for the skin to “bounce back” and for you to see the final appearance of the breasts.Generally speaking (in my opinion), unless the breast implant capsules have thickened (and/or are otherwise symptomatic),  are associated with the ruptured silicone gel breast implants, or if the patient has concerns about "medical conditions" related to the breast implants, capsulectomy is not universally necessary.  For these patients, en block removal of breast implants is a good procedure.
On the contrary, capsulectomy can expose you to additional risks, such as bleeding and minimal size loss.  In other words, any maneuver performed during surgery exposes patients to additional risk (morbidity).

 
 I hope this, and the attached link (dedicated to breast implant removal surgery concerns) helps. Best wishes.

The final look following the removal of implants from a breast augmentation surgery depends upon your DNA, age, and the laxity of your breast skin. In addition, ancillary procedures including a capsulectomy and whether you had certain pathologies requiring removal of the breast implants will also affect your final look. Moreover, the longer you have the implants will also affect the ability of your skin to contract following the implant removal.  Every case must be individualized based upon these characteristics.  Taking all these factors into consideration and having a candid discussion with your physician will help make the best option for you. Good luck!
