Outcome of pectoralis major myomammary flap for post-mastectomy breast reconstruction: extended experience

Abstract

Background: In the past decade there has been an enormously expanding interest among rural Egyptian patients, relatives, and treating oncologists in post-mastectomy reconstruction as an integral part of patient care. We introduced our technique of pectoralis major myomammary cutaneous flap for single-stage reconstruction of large breasts, nipple, and areola.

Methods: The new technique is based on performing modified radical mastectomy in the classic manner, and then using a pectoralis major myocutaneous pedicled flap from the other side in breast reconstruction. The flap is based on the pectoral branch of the thoracoacromial artery, and a sector from the medial part of the healthy breast with its overlying skin and a part of the nipple-areola complex is included with the flap. This technique was used in our center in one 118 patients, with very promising results.

Results: Major flap necrosis was not observed in patients treated with this technique, and there were no local recurrences observed during the follow-up period. Excellent cosmetic results were achieved in 49 of the 118 (41.5%) cases.

Conclusion: We recommend this new technique as a single-stage, simple solution for reconstruction of large breasts after mastectomy.
