Thank you for the question. Keep in mind, that is much too early to evaluate and results of surgery (5 days postoperatively). Also, remember that bra cup sizes will vary from one from manufacturer to another; I suggest that patients do not base their communication and/or satisfaction with the end results of breast surgery on achieving a specific cup size.
The combination breast augmentation / mastopexy surgery differs from breast augmentation surgery alone in that it carries increased risk compared to either breast augmentation or mastopexy surgery performed separately. Furthermore, the potential need for revisionary surgery is increased with breast augmentation / mastopexy surgery done at the same time.
In my opinion, the decision to do the operation in a single or two staged fashion becomes a judgment call made by a surgeon after direct examination of the patient. For me, if I see a patient who needs a great degree of lifting, who has lost a lot of skin elasticity, or whose goal is a very large augmentation then I think it is best to do the procedures in 2 stages (in order to avoid serious complications).
However, doing the procedure in one stage does increase the risks of complications in general and the potential need for further surgery. This increased risk must be weighed against the practical benefits of a single stage procedure (which most patients would prefer).
Conversely, if I see a patient who requires minimal to moderate lifting along with a small to moderate size augmentation (and has good skin quality), then doing the procedure one stage is much safer.
Ultimately, safety and the avoidance of complications should be the first priority. In the long term, if you are not pleased with the size of the breasts a secondary operation may be necessary ( and can be performed much more safely).
I hope this helps.
