Is It Possible for the Pocket To Widen By Movement After Surgery?

I would not worry about the pocket widening at this point.  Your capsule is fairly well formed.  I  do find that implants tend to drift slightly laterally with time. ithink this is due to pectoralis compression. I am sure you will be fine.

 Thank you for the question.

I think that it is possible to “widen” breast implant pockets with overly strenuous exercise or lifting after surgery. I have seen lateral displacement of breast implants occur secondary to what I believe is over activity/lifting. I urge patients to keep their elbows by their sides for the 1st week after surgery and to avoid heavy lifting for at least 6 weeks. It is probably safest to avoid heavy pectoralis muscle activity for several months after surgery.

However,  surgeons'  best efforts and compliant patient activity after surgery lateral movement of the implants is not uncommon  especially with ongoing time and or life experiences such as pregnancy. Correction of the lateral implant malposition can be performed using internal sutures (capsulorraphy).

I hope this helps.

Breast implants can move with time.  There are few natural attachments out laterally to prevent lateral motion. Good support and minimizing activities which push the implants into undesired positions can help. Lateral migration is more likely with larger implants, narrower chests, more curved ribs and stomach sleeping.
