Regional anesthesia in breast reconstruction surgery commonly include thoracic epidurals, intercostal nerve blocks and paravertebal nerve blocks. To date, there remains no standard of care for perioperative pain management and it is usually left to the discretion of the surgeon and anesthesiologist involved to decide which pain blockade is preferable on a case by case basis. While paravertebral and intercostal nerve blocks have shown promising results, they do not provide a complete sensory block to the anterior chest wall, as innervation is supplied not only from the thoracic spinal nerves but also via medial and lateral pectoral nerves off the brachial plexus.
