Is it normal for my implants to shift this much when I lay down? (Photo)

Hi anna305, Thank you for the question and photos. Based on the photos, it appears that you are experiencing lateral displacement. While in some cases, this can be normal. Some women find it bothersome and uncomfortable. You should speak with your plastic surgeon to discuss your concerns and your options to correct this. Only after a thorough examination you will get more information and recommendations.

Thank you very much for your question and photographs.
From your pictures, it appears that you are experiencing mild lateral
displacement. This situation, characterized by the breast implants moving away from the median of the chest, depends on the
individual patient, size of breast skin envelope and the type of implants used.
Women with large natural breasts have their breasts fall to the side when they
lay down. If this problem continues to bother you, I suggest reaching out to
your operating surgeon for his/her advice.

Thank you for the question.  Although some “falling to the 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. Surgical correction is an option (it is certainly not a "necessity").

Generally, the lateral breast implant displacement can be corrected using an internal suture technique, decreasing the size of the pockets and moving the implants toward the midline.   In my practice, I use  a 2 layered suture technique to close off the space laterally (towards the axilla). The use of acellular dermal matrix is an option ( although not usually necessary)  especially if significant implant rippling/palpability is present.  Recurrence of the lateral breast implant displacement is a potential risk associated with the procedure.

 Ultimately, only you can decide whether or not to proceed with revisionary breast surgery:  weighing  the degree of concern you have with your current situation against the potential risks/complications associated with additional surgery will be an important part of the decision-making process.

  Best wishes.
