Modified radical mastectomy with preservation of one or both pectoral muscles is the surgical treatment of choice in stage I and II breast cancer. A surgical anatomic study has been performed, based on post-mortem and intraoperative findings, to investigate origin and course of lateral and medial pectoral nerves and their relations to pectoral muscles and axillary lymphonodes. The results suggest that Patey-Meier operation can produce, in 80 per cent of cases, atrophy and fibrosis of the costoabdominal portion of the pectoralis major muscle as lateral pectoral nerve is generally dissected. On the contrary, radical mastectomy with both pectoral muscles preservation permit also to preserve the nerves during lymphadenectomy if they are recognized.
保留一侧或双侧胸肌的改良根治性乳房切除术是Ⅰ期和Ⅱ期乳腺癌的首选手术治疗方法。基于尸检和术中发现进行了一项外科解剖学研究，以探究胸外侧神经和胸内侧神经的起源、走行及其与胸肌和腋窝淋巴结的关系。结果表明，由于胸外侧神经通常被解剖，在80%的病例中，Patey-Meier手术会导致胸大肌肋腹部部分萎缩和纤维化。相反，如果能识别出神经，保留双侧胸肌的根治性乳房切除术在淋巴结清扫过程中也能够保留这些神经。
