Implants are too wide for my frame. (photos)

I am a firm believer in dimensional planning, which includes matching implant base width to chest wall diameter.  That being said, your breasts have a nice appearance for 5 days post-op, and the ability to feel the edge is more likely due to the amount of tissue you have covering the implant, rather than the width of the implant.  The tissues will relax over the next few months, which will effect how the implants look and feel.  Assuming you have round implants, switching from moderate to high profile will add significant projection and make the upper poles of the breasts appear rounder.  If your current moderate profile implants are not significantly wider than your measured base diameter, switching to high profile may also require you to have significantly larger implants.   In general, waiting 3 months would allow time for the breast tissues to relax and heal, and for you to see your final result.  I would recommend that you discuss your concerns in detail with your surgeon at your next post-op appointment, however, including the changes in your breast size and shape you would experience if you switched your implants to high profile.  It is important that you are certain that switching to high profile implants will accomplish the changes you desire.Best wishes.

You are correct to think about base diameter and implant profile to match a narrow chest. However, because you appear to be thin it is likely that you will feel the implants on the sides with any type of implant, at least a little bit. Wait at least 3-6 months before deciding.

Most Plastic Surgeons agree that it is important to match  the size and  style of the breast implant with th patients breast size and chest width. Larger size breast implants with large implant base widths placed in a patient with a narrow chest width can result  in the implant being able to be felt in the lateral breast. Bcause there is thin tissue in the lateral aspect of the breast, it is this area that most woman often feel or sometimes see the edge of the implant.  Even with replacing the implant witha high profile style impant may not completely eliminate feeling the implant laterally. Placment of fat grafing may be a consideration.
Since it is only five day after surgery it is too early to tell what would be the best. Therefore wait about 3-6 months and then re-evaluate.. 

I'm sorry you are not  happy with your results. The breasts look fine but obviously not the look you are after. Most surgeons prefer to give the tissues about 3 months to heal before reoperating.
