The Comparison Between DEDTI BR and T/E BR
Sponsor: West China Hospital
Summary
This is a national multicenter, prospective, cohort study. The study aims to compare surgical safety (e.g., surgical complication rates), surgery-related indicators (e.g., operation time, number of operations, surgery-related costs, contralateral breast adjustment operation rates), aesthetic outcomes (e.g., BREAST-Q scores, Harris scores, SCAR-Q scores, Ueda scores and QLQ-BR45 scores), and divorce rate between patients undergoing delayed endoscopic direct-to-implant breast reconstruction via an axillary approach and those undergoing the two-stage expander-to-implant breast reconstruction following simple mastectomy.

Delayed endoscopic direct-to-implant breast reconstruction
This technique allows for breast reconstruction in a single operation. Taking dual-plane breast reconstruction as an example, preoperative marking lines are drawn to indicate the contour and inframammary fold of the reconstructed breast. A 4-5 cm axillary incision is placed one finger-breadth below the axillary apex. After making the skin incision, the plane between the pectoralis major and minor muscles is identified and dissected, extending approximately 2 cm below the previous mastectomy horizontal scar. The inner and lower parts of the pectoralis major muscle were then separated. Proceed to the subcutaneous layer and continue to dissociate the flap until it reaches the pre-designed folds and the breast boundary. The use of the TiLOOP® Bra depends on the thickness of the patient's flap. Finally, the prosthesis is placed behind the pectoralis major muscle for breast reconstruction.
Two-stage expander-to-implant breast reconstruction
The two-stage expander-to-implant breast reconstruction involves initially placing a tissue expander to stretch the skin. Once the skin has sufficient capacity, a second surgery is performed to replace the expander with a breast implant. The expander can be gradually adjusted based on the patient's skin expansion progress, physical recovery, and aesthetic needs to achieve optimal reconstruction results.
