title: The modified extended mastectomy using the trap-door method as a staging operation.
abstract: The choice of operation for breast cancer must be directed towards giving the best chance of local control of the disease. Extended radical mastectomy may be beneficial for patients with internal mammary lymph node metastases, although it has remained controversial. The anterior chest defect created by extended radical mastectomy should be avoided in patients with no metastasis in the internal mammary lymph nodes. This paper, proposes a new technique of modified extended mastectomy using the trap-door method as a staging operation and an intermediate operation between modified radical mastectomy and extended radical mastectomy. In this operation, the axillary dissection could be performed by reflecting the pectoralis major muscle and the internal mammary lymph nodes could be dissected by reflecting the parasternal chest wall in trap-door fashion. In cases in which the metastasis is histologically found in the internal mammary content, extended radical mastectomy by sternal splitting is preferred.
