The anatomy of the pectoral nerves and its significance in breast augmentation, axillary dissection and pectoral muscle flaps.

Background: In many plastic surgeries, a detailed understanding of the pectoral nerve anatomy is often required. However, the information available on the anatomy of pectoral nerves is sparse and unclear. The purpose of this study is to provide detailed anatomical information on the pectoral nerves to allow for their easy intra-operative localisation and to improve the understanding of the pectoral muscle innervation.
