Breast Implant Dropped Below Crease - Do I Need a Revision?

Some asymmetry in breast shape is common after breast augmentation surgery, and often this will resolve within the first 6 months of surgery. You should discuss any worries you have with your plastic surgeon, although you may prefer to wait several months before deciding to proceed with additional surgery.

You are still in the early post operative period.  While your specific condition can't be determined without a photo, your circumstance is somewhat common.  If you have an experienced board certified PS then trust his or her judgment.  He/she has likely seen thousands of breast augmentation patients and knows the normal post op routine.  However, if you are persistently unsure of his/ her opinion then seek a second opinion.
