Mapping axillary sensory cutaneous nerves for enhanced analgesic approaches in axillary surgery: a cadaveric study

Innervation of the breast includes branches of thoracic intercostal nerves, the superficial cervical plexus, the brachial plexus, and the intercostobrachial nerve (ICBN). Commonly used blocks for breast surgery provide incomplete analgesia of the axillary region. This cadaveric study aims to identify and map the axillary sensory cutaneous nerves.
