Why is One Boob Bigger Than the Other?

No two breasts are ever of the same size and shape, but a significant difference means a phone call to your plastic surgeon for an appointment and a hands on evaluation.  Your pre-op pictures in your chart may show that your breasts weren't even in the first place.  Many patients do not look at their pre-op breasts closely because they really don't like what they see.  On the other hand, a complication may have developed and I am sure your plastic surgeon would want the opportunity to evaluate your breasts, and treat any complication that may have caused the asymmetry. 

Thank you for your question and for sharing your photos. During the post-operative period the breast are swollen, and the breast implants appear in a much higher position. Over time they descend and fills out the lower half of the breast. In addition, it is not uncommon for one breast to be more swollen than the other and may even out with time (unless they were asymmetric in size to begin with). It may take several months for this to happen and can be encouraged with breast massage and compression. It may appear that the breast enlarges as the lower aspect of the breast fills out (at the expense of the upper portion of the breast).At 8 months, I would revisit with your surgeon to discuss your results and assess if there are options to help improve the size/shape/nipple symmetry.

As you can imagine, without direct examination or viewing pictures it is not possible to give you precise advice. Your plastic surgeon is in the best position to rule out complications (such as capsular contracture) and to advise you.

Keep in mind, that a mild to moderate degree of breast asymmetry is to be expected ( naturally or after breast surgery).  If the asymmetry is significant and/or worsening,  revisionary surgery may be necessary to improve your situation.

Again, your plastic surgeon will be in the best position to assess your situation.

Best wishes.
