of the neurovascular bundle (NVB) represents the denervation point (DP).” The NVB (thoracoacromial artery and vein, plus the lateral pectoral nerve) may be the guide for local anesthetic applications in order to achieve pectoral muscle denervation. “Routine botulinum toxin infiltration of the chest wall musculature at the time of mastectomy and immediate reconstruction… would paralyze the muscles and reduce the postoperative pain caused by muscle spasm.” Damage The lateral pectoral nerve can be damaged, particularly during surgery, by cauterisation and avulsion. Trauma to the brachial plexus can cut off innervation to the lateral pectoral nerve. See also Medial pectoral nerve References Additional images External links Photo at mun.ca Nerves of the upper limb
