Will my breasts drop and look teardrop shape and after swelling will they be bigger? Why is there such a big gap? (photo)

Judging by your before photo you had the same gap between your breasts then and the surgeon must centre any implant on your existing breast which in many women is located more on the slop of their chest leaving quite a large gap - if you bring the implants in more you leave the nipple and you breast out to the side which would not look right. You are very slim so everything shows more and the challenge is to make things look natural - generally that means a more conservative implant choice 240-300  and under the muscle and this is the course your surgeon has followed. Things look more unnatural right now because you have a lot of spasm in your pect muscles which are swelling the upper part of your breast and making your implants look higher - I think things will settle nicely .I do not think going to a D or DD and being natural at the same time would have been possible due to how slim you are . - sometimes there is a tradeoff between size and naturalness

Your pictures suggest you are early on in your postop course. Over the next several weeks, as swelling subsides, the implants should drop and appear more and more natural. Be sure to follow up with your operating surgeon so that they may monitor your progress.

Thank you for your question and photos.

From the photos it is clear that you are early in the
recovery period as implants still need to drop.

I humbly request you to not be discouraged and know that you
are not alone in feeling this. Large number of women experience differences in
their breasts few days to few weeks after surgery and feel awful. After waiting
for a few months, they finally get the results they were hoping for.

Implants initially sit high up because the chest muscles and
surrounding breast tissues have not become accustomed to the implant resulting
in tightness. You have to allow gravity to take effect, and overtime, natural
tissue expansion will allow the implants to fall into place causing your
breasts to appear more natural, softer, and rounder. Once that happens, the
implant will sit directly behind the breast tissue in a natural 45:55 breast
ratio (tear-drop shape), and the nipples will move up higher. Currently, there
may be excessive upper pole fullness (> 55:45) in both sides, so in time,
this will change.

Please note that it is not uncommon for breasts to heal and
adapt to implants at different rates. In fact, the process I described above
can occur quicker in one breast over another.

Also note that any asymmetry that existed in breasts before
surgery will continue to exist as breast augmentation only works to increase
size of the breasts, and it does not fix asymmetry or address cleavage gaps.

You may have to wait 3-6 months for the final results. You
are early in the recovery process, so there is a lot of time for the “drop and
fluff.” If the breasts still appear different at that point in time, then you
may share your concerns with your surgeon and they should be able to fix the
problem.

With persistent inward and downward breast massaging, along
with pole wraps, the breasts drop providing the natural looks while also slightly
minimizing the cleavage gap.

Patience is key!

With regards to the cleavage gap, it can better be addressed
using the sub-glandular approach, but this was probably not used because you
are very thin and you would have risked implant visibility and palpability
making them look fake.

If you remain unsatisfied with the cleavage gap after 3-6
months, then you can have this fixed by your surgeon. It may require a new
incision in the inframammary fold, but essentially, the surgeon will have to
conservatively release some muscle attachments close to the sternum (breast
bone) to expand the pocket near the midline, while closing the implant pocket on
the outer side of the breast (near the armpit) to enhance cleavage. Your
surgeon may also use a wider implant with more volume to provide the same
projection.

For now, please continue to have regular follow-ups with
your surgeon to make sure your breasts are healing beautifully. Their recovery
instructions should take precedence over all else you read here as they are
better informed about your surgical details.

Hope this helps.
