In the previous breast augmentation surgery, the traditional breast prosthesis can usually be placed behind the pectoralis major and behind the breast. Posterior breast placement can have very good cleavage and correct mild breast ptosis. For some breast tissues, this can achieve very good surgical results, but the disadvantage is that it is easier to touch the prosthesis. For patients with breast dysplasia, because there is too little tissue covering the prosthesis, it is necessary to place the prosthesis under the pectoralis major muscle and cover the prosthesis with the tissue provided by the pectoralis major muscle. The activity of pectoralis major increases the chance of prosthesis displacement.

The improved biplane breast augmentation technique can place the prosthesis partly in the breast and partly under the pectoralis major muscle, which combines the advantages of the traditional two methods and has satisfactory surgical results.

Biplanar breast augmentation can reduce the occurrence of capsular contracture and the rate of secondary operation. Biplanar breast augmentation surgery, if axillary incision is used, can only be carried out with the help of endoscope. This method is the most advanced and difficult operation in breast augmentation surgery at present. Therefore, we must carefully choose experienced plastic surgery hospitals and advanced plastic surgery hospitals.
