Lets see the nomenclature of various surgeries on breast

Simple or Total mastectomy

  • it removes all breast tissue, the nipple-areola complex, and skin.

Extended simple mastectomy

  • Simple mastectomy + removal of level I axillary lymph nodes.

Modified radical mastectomy

  • it removes all breast tissue, the nipple-areola complex, skin and the level I and level II axillary lymph nodes.

Halstead’s Radical mastectomy

  • removes all breast tissue and skin, the nipple areola complex, the pectoralis major and minor muscles and the level I, II and III axillary lymph nodes.

Modified Radical Mastectomy

  • Two forms of modified radical mastectomy are in use

  • Auchincloss (pronounced as ‘aushincloss’) procedure

  • Here both the pectoralis major and minor muscles are preserved with removal of level I and II axillary lymph nodes

  • Patey’s Procedure

  • here the pectoralis minor muscle is removed to allow complete dissection of level III axillary lymph nodes

  • Scanlon’s modification of Patey’s procedure

  • here the pectoralis minor muscle is divided instead of removing. Division of pectoralis minor muscle allows complete removal of level III lymph nodes

  • Halstead Radical Mastectomy

  • In this operation following structures are removed.

  • the whole breast

  • the portion of skin overlying the tumor, which includes the nipple-areola complex.

  • the subcutaneous fat and the deep fascia vertically from the lower border of the clavicle upto the upper quarter of the sheath of the rectus abdominis and horizontally from the strenum to the anterior border of lattissimus dorsi

  • pectoralis major muscle

  • pectoralis minor muscle and clavipectoral fascia

  • upper part of the aponeurosis of the external oblique and anterior parts of a few digitations of the serratus anterior muscle

  • all fatty and loose areolar tissue along with level I, II & III axillary lymph nodes Structures saved are :

  • the axillary vein and the cephalic vein

  • the long thoracic nerve of Bell (Nerve to serratus anterior). The nerve to latissimus dorsi may be sacrified if required.
