Tissue Expander Based Breast Reconstruction clinical trials at University of California Health

Infections after tissue expander breast reconstruction can lead to pain, additional surgeries, and loss of the reconstruction. This study will compare two types of antibiotic carriers used during surgery to help lower the risk of infection. One carrier is a non-absorbable PMMA disc, and the other is an absorbable antibiotic bead. Both release antibiotics directly into the breast pocket after surgery. About 100 patients will be randomly assigned to receive one of these two carriers at the time of tissue expander placement. After surgery, small samples of fluid around the tissue expander will be collected during routine clinic visits. These samples will be tested to measure how much antibiotic is present over time. The study will also track infections, tissue expander loss, and other complications during the first 90 days after surgery. The goal is to learn how much antibiotic each carrier delivers and whether one method is more effective at preventing infection.
