Dear Lola73, I'm sorry you've had a troubling time regarding your surgery. Breast augmentation has one of the highest patient satisfaction rates and I'm sure with a minimal revision, your surgery will prove satisfactory as well. Subglandular implants tend to have a very attractive appearance with very pretty definition, however they do tend to have slightly less support than a submuscular placement. This is especially true with a larger implant, and migration can occur. The textured implants due to their frictional coefficient do tend to minimize implant mobility as long as the pocket disection for the implant has been precise. In your situation, what needs to be done is either a capsulorophy (a tightening of the pocket) along the lateral and inferior aspect, or a change to a submuscular position with a new pocket. Timing of this reoperative procedure varies greatly from surgeon to surgeon as well as in the literature. A change to a submuscular placement can be performed earlier. However for a capsuloraphy, a more mature well formed pocket lining, i.e. capsule is necessary. As you are four months out now, this procedure can likely be done now. Most cosmetic surgeons with a complication this early would perform this revisional surgery at no or minimal revisional cost. Best of luck, I'm sure in the future a more satisfactory result may be obtained.
