What Should the Lower Pole Measurement Be for Full D and DD Breasts?

Every person and almost every breast is different.  It would be impossible to give you any one measurement that is correct.  I also am not sure to which measurement you are referring, but I assume you mean inframammary fold to nipple distance.  

In order for your surgeon to have increased your implant size from 325 cc to 550 cc, he/she had to increase the pocket size and lower the fold.  This will result in lowering of the fold and implant.  Two weeks is definitely too early to evaluate whether or not the implants will be symmetric.  Follow-up with your surgeon to discuss this in greater detail.  Good luck.

Like many aspects of plastic surgery, breast surgery is a mixture of science, surgical technique, and art.  There are no 'ideal' measurements that will fit all women's breasts.  There are certain normal ranges but these numbers vary widely from patient patient.  Many women have asymmetries between their breasts that should be noted prior to surgery.  These measurements may have changed after your second breast surgery, and two weeks after surgery is too early to determine the final result.  This result and the position of the implants can be positively altered by proper postoperative care and breast massage as directed by your surgeon.
