375cc under the muscle, are they too far apart? Is that possible that the “drop and fluff” will make them come in? (photos)

The gap that you have has a lot to do with your anatomy and how your muscles are positioned as well as your chest wall.  There is some benefit to placing an implant that maximizes your base diameter to try to get as much cleavage as position.Over time as the implant drop and fluff, they do tend to increase the volume in the lower pole and may add some more fullness medially and laterally.  This will usually take about 4 months time.Once everything has settled you can use a bra to help achieve more cleavage.Hope that helps.

From the photos, it appears that you have a very nice result from your breast augmentation.  Whether or not you are going to have spacing between your breasts is primarily determined by your pre-existing anatomy.  If the medial attachments of your pectoralis muscle are far apart, then you are limited as to how close you can get the implants following surgery.  The only way to decrease this gap is to use fat grafting over the top and medial aspect to effectively fill this area in. As your implants drop it is unlikely that any major changes will occur medially and the implants will certainly not move in medially. I hope that helps and wish you the very best!Warmest regards,-Gregory A Buford MD FACS PCEOBoard Certified Plastic Surgeon and Author

Dear Generous1435,
I understand your concern and it is quite normal to be concerned about the outcome following a breast augmentation surgery. However, you are still in the very early stages of the healing process.Your will need to be patient at this moment and follow what your surgeon has instructed you to do post operatively.At the early stage of the healing process, the tissues around the implants are still swollen. Once the swelling subsides and the implants drop to their final position, you will be able to see the final result of your breast augmentation surgery.

Thank you for your question. It is very difficult to judge your outcome without preoperative photos. You are correct in stating that the end result depends on the patient's preoperative anatomy, in other words, what you get is significantly influenced by what you start with. At 8 weeks post-op, there could still be some change, "drop and fluff", that could positively affect your final outcome. You might consider wearing a very tight postoperative compression vest to try and direct your implants to the middle as much as possible. It does seem that the implant on the left side of your picture is positioned further from the middle. This could be a preexisting condition or it could improve with time. As your implants settle down, many patients perceive that they get a little bigger, especially in the lower half of the breast and in its overall projection. 375cc is a good size initial implant. While you might have been able to go a little bigger, the incidence of complications, especially implant malposition, increases significantly as implants get larger. A bigger implant could possibly make you have more fullness centrally, particularly if the diameter of the implant was bigger and there was room to make the new pocket positioned more to the middle. Again, this would be determined by your preoperative anatomy. 

Thank you for your question. It is not uncommon to have swelling. Breasts may not heal at the same rate, causing one breast to appear different than the other. It can take up to 12 weeks for the implants to settle and you to see the final result. Depending on your anatomy prior to surgery the gap may or may not change as you continue to heal. Give it a little more time to allow your body to fully heal and the implants to settle. Follow up with your board certified surgeon to address your concern. Good luck!
