Sensory Restoration in Abdominally Based Free Flaps for Breast Reconstruction Using Nerve Allograft.

Background: Neurotization in breast reconstruction can be performed with the aid of nerve grafts and conduits to decrease the tedious dissection and overcome size mismatch. However, there has yet to be a formal analysis of this approach. The goal of this study was to evaluate sensory recovery after neurotized abdominally based free flaps for breast reconstruction using the authors' novel technique and analyze factors that could affect sensory recovery.
