Does my implant take longer to drop because I'm small? (photo)

Implants taken longer to drop?This is a really excellent question! I don’t think it’s just the fact that you’re so small and 100 to 105 pounds that is causing your implants to take a while to drop. I think the greatest risk factor for this issue, is the fact that you got 445 mL breast implants. These are very large for your tiny frame and they are just going to simply take a long time to drop.Make sure you follow up with your plastic surgeon as much as you can to be sure that your implants are dropping at the appropriate speed.

Smaller implants tend to drop faster than larger implants.   Larger implants take longer to drop, particularly in smaller women.  Larger implants are typically more prone to displace downward or outward.  Recommend that you follow up with your PS if the right implant continues to look displaced.  Massage can help, but larger implants may take 6 months or more to drop to their final levels. 

Your concerns are understandable. Your plastic surgeon, knowing the details  of your situation, will be your best resource when it comes to good assessment, advice, and/or meaningful prediction/reassurance.\
Generally speaking, breast implants will "drop" into the pocket that was created during surgery. The rate of breast implant "settling" may depend on factors such as size of breast implant pocket dissected, tightness of the overlying skin/muscle layers, and size of breast implant utilized. Normally, it takes about 3-6 months (for some patients longer) to see the final result. It is very common for one side to settle faster than the other.
Similarly, it takes a few months for the breasts to "soften" in most cases.  Most of my patients tell me that their breast implants feel "part of them" somewhere between 3 to 6 months after surgery was performed.  As the breast implants "settle", the lower breast poles will round out (generally improving shape), and the nipple/areola complexes will seem to sit higher on each breast mound.
 There is definitely a physiologic and "psychological" (body image)  adaptation process that occurs, at differing rates for every patient, for patients who undergo any type of aesthetic surgery, including breast  augmentation surgery.  Understandably, patients often experience significant emotional "ups and downs" around the time of surgery.
 
In other words: time, patience, and close followup with your plastic surgeon are your best friends here. In cases where significant breast asymmetry persists, the pros/cons associated with revisionary breast surgery (for example, capsulotomy surgery for an implant that is sitting too high or capsulorraphy for a breast implant that is too low) should be carefully considered prior to making decisions whether or not to undergo further surgery. 
 Best wishes for an outcome that you will be very pleased with longer-term.
