[Renaissance of prepectoral implant-based breast reconstruction: theoretical basis and research status].

Objective: To overview the theoretical basis and research status of prepectoral implant-based breast reconstruction. Methods: The domestic and foreign researches on the application of prepectoral implant-based breast reconstruction in breast reconstruction were retrospectively analyzed. The theoretical basis, clinical advantages, and limitations of this technique were summarized and the future development trend in this field was discussed. Results: The recent advances in breast cancer oncology, the development of materials and the concept of oncology reconstruction have provided a theoretical basis for prepectoral implant-based breast reconstruction. The selection of patients and the experience of surgeons are crucial for postoperative outcomes. Ideal thickness and blood flow of flaps are the most important considerations for the selection of prepectoral implant-based breast reconstruction. However, its long-term reconstruction outcomes and clinical benefits and risks in Asian populations still need to be confirmed by more studies. Conclusion: Prepectoral implant-based breast reconstruction has a broad application prospect in breast reconstruction following mastectomy. However, the evidence is limited at present. Randomized study with long-term follow-up is urgently in need to provide sufficient evidence to evaluate the safety and reliability of prepectoral implant-based breast reconstruction.
