Is dual plane and biplanar the same technique?

Yes, dual plane and biplanar means the same, in that the implants are partially under the muscle and partially under the breast tissue. The lower part of the muscle is released, such that only the upper pole of the breast implant is covered by muscle. You may here it referred to as dual plane (biplanar) 1, 2 or 3 depending on the amount of muscles released.

These are very similar. Essentially, the pectoral muscle only covers the upper breast yet offers advantages.An exam and consultation with a plastic surgeon is recommended to discuss your options and expectations.

Thank you for your question.  As others have described this is a technique where the muscle is cut to either fit a very large implant or to hide an implant behind a saggy breast. I personally believe that this technique is a disservice to women because it weakens the only source of support to keep an implant in place. Women who have undergone this procedure often exhibit malposition and leteralization (implants fall to the sides of the chest) of the implants. Women often require expensive revisionary surgery where some type of alloderm is required to restore the implant back in place.  I hope this allows you to make a more informed decision. Best wishes and kind regards, 

Thank you for sharing your excellent question.  Yes, dual-plane and biplaner refer to the same implant position, with a portion of the implant resting beneath your pectoralis major muscle and the other by your natural breast tissue.  Hope this helps.

Yes, they both refer to the muscle being released from the gland during your augmentation. These are small technical points that have a place in augmentation and is ultimately determined by your plastic surgeon.
