Asymmetry of scars, breast lower breasts and drain plug hole. Can I expect to gain symmetry in time?

It appears that you are very early in your post-operative healing and recovery. It takes a full year for a scar to completely heal and mature, and hopefully the scars will be minimal or close to invisible, in which case any asymmetry in the scar placement will be irrelevant.

It is best to stay in touch with your surgeon and follow his or her recommendations. If you do not feel comfortable with your surgeon then I recommend a second opinion in person. This far it appears you have a very nice result that should only get better over time. Felicitations.

Your right implant is sitting a little high which will make the scars look uneven when they may actually be fairly even. Talk to your surgeon about helping the right breast settle with oral Accolate and external ultrasound treatments unless you are still very early in the healing process. If you are still early, then wearing the chest band will be helpful.
