Wide gap when lying down after breast augmentation. What can be done?

All breasts to the side of bit when lying on one's back. However if the gap between your breasts is too large this can be surgically corrected utilizing sutures that close the outer portion of the implant pocket. A big question is whether this is worth it to you that is should one undergo a surgical procedure with inherent risks to improve this situation. If you are happy with your breasts when you're standing upright, you may wish to thank about all your options. Discuss this with your surgeon regarding risks and possible benefits.

To have some separation in the middle of the breast after breast augmentation surgery is normal, but excessive width could be due to pocket expansion. If the pockets have expanded laterally you will need to have a surgical repair known as capsulorraphy where the surgeon will go in using an internal suture to close the pockets laterally, pushing the implants inward to minimize the gap.

Thank you for your question.  It sounds like from your description that the lateral (outer) pocket may be too large allowing the implant to displace.  This can be corrected by narrowing the pocket down, or by creating a new pocket and being mindful not to oversize it.  Good luck.
