3D-printed Biodegradable Breast Implants for Breast Restoration

The purpose of this clinical trial is to evaluate the cosmetic effect of breast reconstruction based on 3D-printed biodegradable material breast implants in personalized breast reconstruction and the quality of life of patients, with traditional breast-conserving surgery and traditional breast reconstruction as controls. It will also explore the safety of breast reconstruction based on 3D-printed biodegradable material breast implants in personalized breast reconstruction. The main question it aims to answer is: Can breast cancer patients who are not suitable for breast-conserving surgery use 3D-printed biodegradable material breast implants for breast reconstruction? Do patients who undergo breast reconstruction based on 3D-printed biodegradable material breast implants have advantages over those who receive breast-conserving surgery or traditional silicone prosthesis breast reconstruction surgery in terms of cosmetic effects, quality of life and safety? What medical problems may occur when participants use 3D-printed biodegradable material-based breast implants for breast reconstruction? Participants will: Non-random enrollment. In the experimental group, breast reduction surgery based on 3D-printed degradable biological implants was received; In control group 1, traditional breast-conserving surgery was received; Traditional silicone prosthesis breast reconstruction was received in control Group 2.
