How can I fix no gap and possible uniboob? (Photos)

Without knowing what you looked like before surgery, it is tough to know if this is truly symmastia or simply amplification of something that was there before.  Best to talk to the Plastic Surgeon who performed your surgery and consult with him/her about thoughts and possible treatment. I hope that helps and wish you the very best!Warmest regards,-Gregory A Buford MD FACSBoard Certified Plastic Surgeon and Author

Your synmastia requires a surgical correction. The best option surgically is to create a new pocket (neosubpectoral) and to support the new pocket medially with mesh to ensure longevity. By creating new pockets, your new implants will be separated and your cleavage should be excellent. This is an operation that should be performed by a board-certified plastic surgeon, particularly one with an expertise in aesthetic revision surgery. Good luck!
