I'm post op 1 wk, 610 cc in right axillary under muscle & 560 in left. Will they increase in size once they drop? (Photo)

They will likely drop more but the size will not change.  Having said that, you may be happier with the apparent size once things settle and drop.  Speak with your plastic surgeon.

Usually between 5-8 days post operatively, patients go through a depression.  I find this true for all types of cosmetic surgery, but even more so with reference to breast augmentations.I believe this is a true chemical depression, post anesthesia, post taking pain pills, putting up with the discomfort due to post operative swelling all of which comes to a crescendo about the 5th or 6th day post surgery.Fortunately, most of us are not used to having surgery after surgery after surgery, therefore this feeling of depression needs to be pinned on something, and the chemicals from anesthesia rarely come to mind as the culprit.  If you were hoping for big implants, then the implants are not big enough.  If you were hoping that the implants not be too big, then the implants appear to be too big.  The good news is that this depression is very time limited, and as long as you have a good support team at home and within the plastic surgeon's office, you will get by this depression quickly.  It is not that the implants grow bigger or smaller, but your feeling about your implants will improve as you body chemistry returns to normal. 

and your results look very good at this point.  You even look a little top heavy on your photos.  What look did you have in mind when you signed up for this?  Work on healing from this and getting the absolute best results you can.  By that time that happens, you may be more accepting of your very generous size and avoid more surgery and costs.

Appears as an excellent excellent early result. Yes dropping in to pocket can help. But there will be no increase in size... 

At only 1 week after breast augmentation surgery, you cannot judge the final results. Especially with sub muscular breast augmentation, it takes 3 to 6 months for all of the soft tissue (muscle and breast) to soften and accommodate the implant. The muscle in particular takes time to stretch over the implant - early on it is swollen and compresses the implant. Over time, the muscle and your breast tissue will stretch and allow the implant to settle and to drop - this often correlates to feeling softer, and in ways feeling "bigger" because the implants fall and project a little more. Many patients initially feel depressed after breast augmentation and feel that they are too big or too small, or that the shape is not right. Give your self time to adjust, and give your body time to adjust. Follow your surgeons recommendations and wait for about 3-6 month before judging the final results.

It is not that they will get larger when they drop, but they will definitely look a bit different as they descend into the pocket. Best of luck.

 Congratulations on having undergone the breast augmentation procedure; based on your photographs, it seems like your plastic surgeon has done a very nice job for you. It may be helpful for you to know that it is not unusual for patients to feel that they are “too small” or “too big”,   early on after breast augmentation surgery.  Most patients who feel this way ultimately are pleased with the results of surgery. Yes,  in my experience, many patients who feel that they are too small immediately after surgery find, as the breast implants “drop and fluff”,  that the breasts actually appear larger to them. I routinely ask my patients  to wait at least 3-6 months before   evaluating the end results of the breast augmentation surgery.  This waiting time allows patients to (uaually) physically and psychologically adapt to the new body image.  There are both physiological and “psychological” reasons to wait on having  revisionary surgery. From the physiological standpoint, it takes many months ( and even up to one year) to see the final results of surgery. factors such as swelling,  tissue contraction,  skin redraping,  implant shifting etc. come into play.From the psychological standpoint, patients undergo an “adaptation period"  during which time they get used to the changes that the surgical procedure has brought about.  Severe emotional swings can also occur after any type of surgical procedure.
Obviously, it is best for patients not to be making important decisions ( for example about the results of surgery and/or the need for additional surgery) while they are experiencing these emotional “ups and downs”.I hope this helps.

Thank you for your question.  Your result looks excellent this early after surgery.Understand that the implants are spread out over your chest this early and has the implant drops and fills the lower pole of the breast they should look certainly more natural and possibly fuller.
