Total mastectomy with axillary dissection. A modified radical mastectomy.

A technic for total mastectomy with complete axillary dissection has been described. The procedure utilizes division of the pectoralis major muscle between its clavicular and sternal portions, perservation of its innervation, and reconstruction after completion of the dissection. The pectoralis minor muscle is resected. This modification facilitates a thorough axillary dissection, particularly at the apex, while preserving the cosmetic and functional benefits of the Patey operation.
