Should I be worried about having lateral displacement when lying down? (Photo)

 I am sorry to hear about your concerns after breast augmentation surgery.   Although some “falling to these sides” of breast implants is quite normal when you lie down, if this occurs “excessively”, it may be a concern to patients.  This phenomenon is called lateral displacement of the breast implant;  it may be of concern from the visual and the discomfort standpoints. Surgical correction is an option.In your case specifically, based on the photograph, I am not visualizing significant breast implant displacement.  Your breast implants seemed to be equal distance from your sternal midline and the nipple/areola complexes appear to be well centered on each breast mound.
  Best to communicate specific concerns/questions directly with your plastic surgeon.
 Best wishes.  

Thank you for your question. It is very early to know about lateral displacement in your case. It is very common breast to drift to lateral side. If it is excessive then it is called lateral displacement and it may be because dissection at the time of surgery or large implants etc. Please continue to f/u with your PS and re evaluate in 3-4 months.
