Nerve Grafting for Breast Reconstruction

This trial aims to determine if a donor nerve graft (allogeneic nerve grafting) used during breast reconstruction can help women regain sensation in their breasts and nipples after surgery. Researchers will compare sensation in the breast receiving the nerve graft with the one that does not. Women planning to undergo a nipple-sparing mastectomy with implant reconstruction, who have not had this surgery before, might be suitable candidates for this trial. Participants will undergo sensation tests and complete surveys before surgery and at several intervals over the next two years. As a Phase 4 trial, this research focuses on understanding how the already FDA-approved treatment can benefit more patients.

Previous studies have shown that using donor nerve grafts is safe. Research indicates these grafts are often well-tolerated, achieving success rates over 95% in related plastic surgery procedures. Specifically, studies on repairing peripheral nerves with processed donor nerve grafts demonstrated meaningful recovery rates, with 61% of patients in one study experiencing significant improvement. This suggests the approach is likely safe for breast reconstruction.

Researchers are excited about allogeneic nerve grafting for breast reconstruction because it has the potential to restore sensation in reconstructed breasts, which is not typically achieved with standard reconstruction methods. Unlike traditional reconstruction that often results in numbness, this approach involves using donor nerve tissue to reconnect sensory pathways. This could significantly enhance the quality of life for patients by providing a more natural feel and sensation after surgery.

Research has shown that using donated nerve tissue can improve sensation after breast reconstruction. In this trial, participants will undergo bilateral nipple-sparing mastectomy with immediate implant-based breast reconstruction. One side will receive allogeneic nerve grafting, while the other side will undergo standard reconstruction without nerve grafting, serving as a control. Studies have found that adding these nerve grafts may help restore sensation in the breast and nipple area. Patients often report improved physical and emotional well-being when they regain sensation. This improvement occurs because the grafts help nerves reconnect and grow back. While many patients experience positive results, outcomes can vary. Overall, evidence supports the potential benefits of nerve grafting in enhancing sensation after a mastectomy.⁵⁶⁷⁸⁹
